Creating a Site: Creating a Toposurface

Creating a Toposurface
12/20/09 9:15 - 10:15am

Import contour data to create a toposurface:

  1. Click Insert tab, then Import panel, then Import CAD.
  2. In the Import CAD Formats dialog:
  • In the left pane, click Training Files, and select Common\Site Plan.dwg.
  • For Colors, select Preserve.
  • Verify that the Current view only option located on the left side of the dialog is cleared.
    NoteIf you select the Current view only option when importing the DWG, then the drawing is added as a drafting item and is view-specific. You cannot use a drafting item to create a toposurface.
  • Click Open.
3. Zoom to fit the drawing in the view. ('ZF' is the keystroke shortcut)
The drawing must be moved to the right to ensure that the building is modeled close to the origin of the project. The elevation markers in the project template point to the origin. It is critical that you create Revit Architecture projects as close to this origin as possible.

4. In the drawing area, select the imported site plan.

5. Click Modify Site Plan.dwg tab, then Modify panel, then Move.

6. Click near the center of the building to enter the move start point.

7. Click to the right outside of the building to enter the move end point, as shown.
Position the center of the building close to the central area indicated by the elevation markers. (Exact placement is not important.)

8. Press Esc.

9. Click View tab, then Create panel, then 3D View drop-down, then Default 3D.
You can see results more clearly when creating the toposurface from a 3D view.
Note: The contours in the DWG imported file are drawn with a z value. Revit Architecture uses these values to create 3D points and generate the toposurface object.

10. Click Massing & Site tab, then Model Site panel, then Toposurface.

11. Click Create Topography Surface tab, then Tools panel, then Create from Import drop-down, then Select Import Instance.

12. In the drawing area, select the site plan.

13. In the Add Points from Selected Layers dialog:
  • Click Check None.
  • Select C-TOPO-MAJR.
  • Select C-TOPO-MINR.
  • Click OK.

The DWG site plan contains information in addition to the contour lines. Use the Add Points from Selected Layers dialog to filter out the lines you do not want to use in creating the toposurface.

14. Click Create Topography Surface tab, then Surface panel, then Finish Surface.

Note: Using an imported instance, such as a DWG file or a points file, decreases the time it takes to input points and create a toposurface. Also, you can create or add points used to define the toposurface manually. For additional information about the manual process of creating a toposurface, refer to Autodesk Revit Architecture 2010 Help.

Turn off the visibility of the DWG

  1. In the Project Browser, expand 3D Views, right-click {3D}, and click Properties.
  2. In the Instance Properties dialog, for Visibility/Graphics Overrides, click Edit.
  3. On the Imported Categories tab of the Visibility/Graphic Overrides for 3D View: {3D} dialog, under Visibility, clear Site Plan.dwg, and click OK.
  4. In the Instance Properties dialog, under Extents, select Section Box, and click OK.
    The DWG no longer displays, and a section box is drawn to the extents of the toposurface geometry.


Create a sectioned edge

  1. In the drawing area, select the section box.
  2. Drag the controls to adjust the edges of the section box to cut the toposurface with the box. (Exact placement of the edge is not important.)
    When the section box edge cuts the toposurface, a cut pattern is displayed on the edge of the toposurface, making it easier to see the topography.

View the toposurface
  1. Right-click the section box, and click Hide in View, then Elements.
  2. On the View Control Bar, click Model Graphics Style, then Shading with Edges.
  3. On the navigation bar, click the Full Navigation Wheel, and use the Orbit tool to spin the toposurface to view it at various angles.

Modifying Project Browser Organization

Modifying Project Browser Organization
12/18/09 1:45-2:00pm

In a typical project, you often produce multiple packages of related drawings. These drawings and sheets can become so numerous that navigating a lengthy Project Browser list can be cumbersome. To organize the views and sheets into sets of deliverables, you can use the Project Browser settings to instantly modify how the Project Browser groups and sorts.

In this exercise, you modify the Project Browser organization and create methods of grouping and sorting the views and sheets.

Organize the Project Browser by views

  1. In the Project Browser, expand Views (all), expand Floor Plans, and expand 3D Views.

    Notice that the views are listed alphabetically.

  2. In the Project Browser, expand Sheets (all).

    Notice that the sheets are listed alphanumerically based on the sheet number.

  3. Open each of the 3D views in the following order, and notice the progression of each view:
    • Main Bldg - Phase 1-Structure
    • East Wing - Phase 2-Structure
    • West Wing - Phase 3-Structure
    • Completed Project-Structure
    • Completed Structure w/ Roof&Floors
    • Completed Project

    Each of the 3D views varies by phase and discipline.

  4. Click View tab, then Windows panel, then User Interface drop-down, then Browser Organization.
  5. On the Views tab of the Browser Organization dialog, select Discipline, and click OK.
    In the Project Browser, notice that Views are divided into Architectural and Structural disciplines.
  6. In the Project Browser, expand both the Architectural and Structural views.
  7. On the Windows panel, click User Interface drop-down, then Browser Organization.
  8. Select Phase, and click Apply.
    In the Project Browser, notice that views are grouped by phase.
  9. In the Browser Organization dialog, select Type/Discipline, and click OK.
  10. In the Project Browser, expand each view type, and notice that each is grouped by discipline.

Specifying Units of Measurement, Temporary Dimensions, and Detail Level Options

Specifying Units of Measurement, Temporary Dimensions, and Detail Level Options
12/15/09 8:15pm-8:45pm

In this exercise, you modify 3 settings that have a broad impact on the project. In the first section, you specify the project units of measurements. Unless overridden, dimension values display using this setting. In the second section, you modify the temporary dimension settings. In the final section, you modify the detail level assignments.

Set units of measurement

  1. Click Manage tabProject Settings panelProject Units.
  2. In the Project Units dialog, for Length, click the default value.
  3. In the Format dialog, for Rounding, select To the nearest 1/16", and click OK.
  4. In the Project Units dialog, for Area, click the default value.
  5. In the Format dialog:
    • For Rounding, select 0 decimal places.
    • For Unit symbol, select SF.
    • Click OK.

    Modifications to area rounding are displayed in schedules and area tags.

  6. Click OK.

    Unless overridden, dimensions use these project settings.

Specify temporary dimension properties

  1. Click Manage tabProject Settings panelSettings drop-downTemporary Dimensions.
  2. Under Walls, select Faces.
  3. Under Doors and Windows, select Openings, and click OK.

    In this project, temporary dimensions now snap to the wall faces and to the door and window openings. The location of temporary witness lines can be changed by clicking their controls.

Specify detail levels

  1. On the Project Settings panel, click Settings drop-downDetail Level.

    When you create a new view and specify its view scale, the detail level is specified automatically according to the arrangement in the table.

    TipYou can override the detail level at any time by specifying the Detail Level parameter in the View Properties dialog or the Detail Level icon on the View Control Bar.

    In this table, you use the arrows between the columns to move view scales from one detail level to another. You do not select a view scale to move it. The view scale moves either from the bottom or the top of the column based on the direction.

  2. Between the columns Coarse and Medium, click .

    Notice the 1/4" = 1’ 0" view scale moved to the Medium column. Any new view created using this scale is automatically assigned the detail level Medium.

  3. Click OK.

Modify Snap Increments

In this exercise, you modify snap settings. Snap settings are system settings that are applied to all projects and not saved within a project file. You can turn snap settings on and off, or use the shortcut keys to force a particular snap method. In this exercise, you modify snap increments, work with snapping turned off, and use shortcut keys to control snapping on an instance basis.

Modify snap increments

1. Click the "R" button, then New, then Project to open a new Revit Architecture project.

2. In the New Project dialog, under Template file, click Browse.

3. In the left pane of the Choose Template dialog, click Training Files, and openImperial\Templates\RAC_MSS_Tutorial_Default_i.rte.

4. In the New Project dialog, click OK.

5. Click Manage tab, then Project Settings panel, then Settings drop-down, then Snaps.
Notice that you can modify both length and angular snap increments. As you zoom in and out within a view, Revit Architecture uses the largest increment that represents less than 2mm in the drawing area. You can add an increment by entering the value with a semicolon after it.

6. Under Dimension Snaps, click in the Length dimension snap increments box following the value 4’ ; and enter 1 ;.

7. Under Object Snaps, notice the 2-letter acronyms next to each object snap option.
You can use these shortcut keys at any time when working on the design. For example, if you want to snap an object to a wall midpoint, enter SM, and only midpoint snaps are recognized until you commit an action. After you click to place the object at the midpoint, snapping reverts to the system default settings.

8. In the Snaps dialog, click OK.

9. Click Home tab, then Build panel, then Wall drop-down, then Wall.

10. On the Options Bar, clear Chain.

11. Click in the center of the drawing area, and move the cursor to the right.
Notice that the listening dimension snaps at 4’ increments. If it does not, zoom out until it does so.
A listening dimension refers to the dimension that displays while you are drawing. This dimension reacts to the movement of the cursor and numerical keyboard entries.

Tip: To zoom while drawing, use the wheel button on your mouse. If you do not have a wheel button, you can right-click and select a zoom option from the shortcut menu. While drawing, you can also use the zoom shortcut keys, such as ZO to zoom out.

12. While drawing a generic straight wall, zoom in until the listening dimension snap increment shifts to 1’.
This is the increment that you added previously.

Draw without snapping

13. While drawing the wall, enter the shortcut key SO to turn snaps off.
Notice that when snapping is turned off completely, the listening dimension reflects the exact length of the wall as you move the cursor to the left or right.

14. Click to set the wall endpoint.

15. Click in the drawing area to start a second wall, and move the cursor to the right. Do not set the wall end point.
Notice that snapping is once again active. When you use shortcut keys to control snapping, the command is only active for one click of the mouse.

Use snapping shortcut keys

16. Click Modify.

17. Click Home tab, then Build panel, then Wall drop-down, then Wall.

18. Place the cursor over the horizontal wall you added previously.
Notice that the cursor snaps to various points on the wall. If you move the cursor along the wall, it will snap to the endpoints, the midpoint, and the wall edges.

19. Enter SM.
This is the snap shortcut key that restricts all snapping to midpoints.

20. Notice that the cursor now snaps only to the midpoint of the wall.

21. Click to start the wall at the midpoint.

22. Move the cursor downward, and specify the wall endpoint.

23. Click Manage tab, then Project Settings panel, then Settings drop-down, then Snaps.

24. Under Dimension Snaps, click in the Length dimension snap increments box, and delete the value 1’ ;.
Make sure you also delete the semicolon.

25. Click OK.

26. Close the file without saving it.

Create A Library

Specify library settings and create a library

This library tab will enable you to create a direct link to folders that contain files that you create. there will be a link on the left side of the open and save dialogs.

1. In the Options dialog under the File Locations tab, click Places.

2. In the Places dialog, notice the list of library names.
The list is dependent on the options that you selected during installation. Each library path points Revit Architecture to a folder of families or training files. You can modify the existing library names and path, and you can create new libraries. An icon for each library displays in the left pane of all Revit Architecture Open, Save, Load, and Import dialogs.

When you are opening, saving, or loading a Revit Architecture file, you can click on the library folder located in the left pane of the dialog. In the following illustration, notice that the libraries display as icons in the left pane of the dialog. You can scroll the left pane to access all of the library icons.

3. In the Places dialog, under Libraries, click the Plus button (Add Value).

4. Click in the Library Name field of the new library, and change the name to My Library.

5. Click in the Library Path field for My Library, and click the icon that displays on the right side of the field.

6. Navigate to C:\My Documents or a folder where you want to create a personal library of Revit Architecture projects, templates, or families, and click Open.

Tip: You may want to create a new folder first, and select it as the library path.
Note: The new library displays in the left pane of all Revit Architecture Open, Save, Load, and Import dialogs.

7. Click OK twice.

8. Click Open.

9. In the left pane of the Open dialog, click the My Library icon.
Notice that Revit Architecture navigates directly to the library path. If you work in a large office, you may want to set up an office library on a network path to increase productivity and maintain office standards.

    Revit 2010: Understanding Terms

    "Most of the terms used to identify objects in Revit Architecture are common, industry-standard terms familiar to most architects. However, some terms are unique to Revit Architecture. Understanding the following terms is crucial to understanding the software.

    Project: In Revit Architecture, the project is the single database of information for your design—the building information model. The project file contains all information for the building design, from geometry to construction data. This information includes components used to design the model, views of the project, and drawings of the design. By using a single project file, Revit Architecture makes it easy for you to alter the design and have changes reflected in all associated areas (plan views, elevation views, section views, schedules, and so forth). Having only one file to track also makes it easier to manage the project.

    Level: Levels are infinite horizontal planes that act as a reference for level-hosted elements, such as roofs, floors, and ceilings. Most often, you use levels to define a vertical height or story within a building. You create a level for each known story or other needed reference of the building; for example, first floor, top of wall, or bottom of foundation. To place levels, you must be in a section or elevation view.

    Level 2 work plane cutting through the 3D view with the corresponding floor plan next to it

    Element: When creating a project, you add Revit Architecture parametric building elements to the design. Revit Architecture classifies elements by categories, families, and types.

    Category: A category is a group of elements that you use to model or document a building design. For example, categories of model elements include walls and beams. Categories of annotation elements include tags and text notes.

    Family: Families are classes of elements in a category. A family groups elements with a common set of parameters (properties), identical use, and similar graphical representation. Different elements in a family may have different values for some or all properties, but the set of properties—their names and meaning—is the same. For example, 6-panel colonial doors could be considered one family, although the doors that compose the family come in different sizes and materials.

    There are 3 kinds of families:

    • Loadable families can be loaded into a project and created from family templates. You can determine the set of properties and the graphical representation of the family.
    • System families include walls, dimensions, ceilings, roofs, floors, and levels. They are not available for loading or creating as separate files.
      • Revit Architecture predefines the set of properties and the graphical representation of system families.
      • You can use the predefined types to generate new types that belong to this family within the project. For example, the behavior of a wall is predefined in the system. However, you can create different types of walls with different compositions.
      • System families can be transferred between projects.
    • In-place families are custom families that you create in the context of a project. Create an in-place family when your project needs unique geometry that you do not expect to reuse or geometry that must maintain one of more relationships to other project geometry.
      • Because in-place families are intended for limited use in a project, each in-place family contains only a single type. You can create multiple in-place families in your projects, and you can place copies of the same in-place family element in your projects. Unlike system and standard component families, you cannot duplicate in-place family types to create multiple types.

    Type: Each family can have several types. A type can be a specific size of a family, such as a 30” X 42” title block or a 32" x 84" door. A type can also be a style, such as default aligned or default angular style for dimensions.

    Instance: Instances are the actual items (individual elements) that are placed in the project and have specific locations in the building (model instances) or on a drawing sheet (annotation instances).

    Revit 2010: Element behavior in a parametric modeler

    "In projects, Revit Architecture uses 3 types of elements:

    • Model elements represent the actual 3D geometry of the building. They display in relevant views of the model. For example, walls, windows, doors, and roofs are model elements.
    • Datum elements help to define project context. For example, grids, levels, and reference planes are datum elements.
    • View-specific elements display only in the views in which they are placed. They help to describe or document the model. For example, dimensions, tags, and 2D detail components are view-specific elements.


    There are 2 types of model elements:

    • Hosts (or host elements) are generally built in place at the construction site. For example, walls and roofs are hosts.
    • Model components are all the other types of elements in the building model. For example, windows, doors, and cabinets are model components.

    There are 2 types of view-specific elements:

    • Annotation elements are 2D components that document the model and maintain scale on paper. For example, dimensions, tags, and keynotes are annotation elements.
    • Details are 2D items that provide details about the building model in a particular view. Examples include detail lines, filled regions, and 2D detail components.

    This implementation provides flexibility for designers. Revit Architecture elements are designed to be created and modified by you directly; programming is not required. If you can draw, you can define new parametric elements in Revit Architecture.

    In Revit Architecture, the elements determine their behavior largely from their context in the building. The context is determined by how you draw the component and the constraint relationships that are established with other components. Often, you do nothing to establish these relationships; they are implied by what you do and how you draw. In other cases, you can explicitly control them, by locking a dimension or aligning 2 walls, for example."

    Revit 2010: How does it keep things updated?

    "A fundamental characteristic of a building information modelling application is the ability to coordinate changes and maintain consistency at all times. You do not have to intervene to update drawings or links. When you change something, Revit Architecture immediately determines what is affected by the change and reflects that change to any affected elements.

    Revit Architecture uses 2 key concepts that make it especially powerful and easy to use. The first is the capturing of relationships while the designer works. The second is its approach to propagating building changes. The result of these concepts is software that works like you do, without requiring entry of data that is unimportant to your design."

    Revit 2010: What is meant by parametric?

    "The term parametric refers to the relationships among all elements of the model that enable the coordination and change management that Revit Architecture provides. These relationships are created either automatically by the software or by you as you work. In mathematics and mechanical CAD, the numbers or characteristics that define these kinds of relationships are called parameters; hence, the operation of the software is parametric. This capability delivers the fundamental coordination and productivity benefits of Revit Architecture: Change anything at any time anywhere in the project, and Revit Architecture coordinates that change through the entire project.

    The following are examples of these element relationships:

    • The outside of a door frame is a fixed dimension on the hinge side from a perpendicular partition. If you move the partition, the door retains this relationship to the partition.
    • Windows or pilasters are spaced equally across a given elevation. If the length of the elevation is changed, the relationship of equal spacing is maintained. In this case, the parameter is not a number but a proportional characteristic.
    • The edge of a floor or roof is related to the exterior wall such that when the exterior wall is moved, the floor or roof remains connected. In this case, the parameter is one of association or connection."

    What is Autodesk Revit Architecture 2010?

    Excerpts taken from the training files within the program...

    "The Revit Architecture platform for building information modelling is a design and documentation system that supports the design, drawings, and schedules required for a building project. Building information modelling (BIM) delivers information about project design, scope, quantities, and phases when you need it.

    In the Revit Architecture model, every drawing sheet, 2D and 3D view, and schedule is a presentation of information from the same underlying building model database. As you work in drawing and schedule views, Revit Architecture collects information about the building project and coordinates this information across all other representations of the project. The Revit Architecture parametric change engine automatically coordinates changes made anywhere—in model views, drawing sheets, schedules, sections, and plans."
