- Legends

"Legends
Legends...place graphic representations of elements in the model to explain the symbology used in the project. Examples...key to symbols in a site plan; typical wall, door, or window types used in a project; or demolition notes on a title block. ...legends are used for views you want to have appear on multiple sheets. ...2D elements derived from the components used in your project. Elements in a legend have no effect on scheduling quantities of elements. ...adding a door symbol to a legend view will not increase the number of instances of that door in the overall project and thus won’t be reflected in the schedule of the door totals.
To create a legend view...click the View tab. On the Create panel, click the Legends button and select Legend. ...then give the legend view a name and associated scale, and you will be presented with an empty view window. To start creating the legend and add content to this view, go to the Annotate tab, and under the Detail panel, click the Component button. Then select Legend Components and start generating the legend.

NOTE: "Legends are the only view type in Revit that can be placed on multiple sheets."

"Types of Views
Drafting Views
"

"Drafting Views
... 2D views specifically designed to show information that is not generated directly from the model....used to show standardized details or information that is typical of a certain area but doesn’t necessarily have a connection with the model. Drafting views can also be used to display detailed 2D information about something in the model."
"drafting views created separately from the model or imported can be referenced in the model and linked to a callout so your drawing sheets always maintain a parametric relationship to their associated details.
...using the Callout Detail tool allows you to create dynamic details that are generated out of the model with 2D drafting elements overlaid on top. ...these details are connected with the model elements, so any model changes are reflected in the details."
"Drafting views can be inserted onto sheets and can also be referenced to sections or elevations as a similar (SIM) condition.
To reference a drafting view to a model, follow these steps:
1. Create your new drafting view: switch to the View tab, and in the Create panel select Drafting View.
2. Import a DWG file, or use detail lines, filled regions, and other drafting tools from the Annotate tab to create the 2D detail.
3. Switch to a view where you want to indicate a callout that will reference this newly created drafting view.
4. Select the View tab again, and from the Create panel choose Callout.
5. Prior to drawing the callout bubble in the model where the detail explains the condition, from the Options bar check the Reference Other View option in the Options bar and choose the drafting view you just created. Now draw the callout bubble where you wish the drafting view to be referenced."

"Types of Views
Elevations
Sections


"Elevations
...created by placing elevation tags into your model. ...when you insert an elevation tag, it dynamically positions itself perpendicular to any wall. ...even in ...nonorthogonal floor plans. ...you can duplicate any elevation by right-clicking the view name in the Project Browser and choosing Duplicate View then Duplicate. This will make a new nondependent elevation view."
"Each elevation symbol is capable of creating four elevation views at once, each facing a different direction. ...If you place an elevation symbol in the middle of a room, by inserting...then highlighting the center of it, you see check boxes that can be used to activate the other elevations. Check or uncheck one of the boxes to turn the elevation on or off..."
"Selecting an activated elevation arrow gives you additional options and displays the
width and depth of the elevation."
"double-click any of the elevation arrows to navigate directly to the corresponding
elevation view, or you can open the elevation views from the Project Browser."
NOTE: Be sure to double click on the graphic line of the arrow, if you click on the middle of it near the number, nothing happens.

"Sections
...properties of section tags are similar to...elevation tags, except the cut plane of the section graphic cannot be moved independently from the section graphic (as with elevation symbols). The view width and depth are defined by the dashed lines when a section is selected, as in the elevation. Use the opposing arrow drag controls to adjust the crop boundary of the section"
"a jointed section cut ...the Section tool has the capability of splitting so that it allows for staggered section lines. ...first draw a section line where you need to establish a view. Next, select the section, and choose Split Segment from the Section panel of the Modify Views tab. This enables the Split tool and allows you to split the section line at any point.
...now each segment of the section cut can be adjusted for location and depth. ...A section line can be cut multiple times..."
NOTE
"For best performance, be sure to limit the depth of your section and elevation cuts only to what you really want to see. ...Revit will calculate all of the information whether or not you see it, so make your section depth as shallow as possible in order to gain in performance and not force Revit to calculate what you do not need to see." This will be one of my twitter RevitNewbie tips!

"Creating New Plan Views with Levels
...default plan view is referred to as a Level 1 view and is organized under Floor Plans in the Project Browser. A level typically represents one story in a building, but as you’ll see later, a level can also be used to reference the position or height of other elements..."

"Creating Levels
"To create a level using the Level tool, you have to be in section or elevation view."
...select the Level command from the Datum panel under the Home tab...draw a level using two mouse clicks to define the start point and endpoint...this will add a new
level and plan view to the model...note that the Level command is disabled
unless you’re actively in an elevation or section view."
"You can also create a level by copying an existing one. ...To create additional levels, open a section or elevation view; select the level line in the view; and, using the Copy command, copy the existing level, thus creating a new one.
...the copied level doesn’t automatically create a new view (you will see in the
Project Browser that no new plan has been added); it only gives you another level graphic in the project that shows in elevation or in section. ...useful when you need another benchmark in elevation to show heights or want to associate geometry to a level, but you don’t necessarily want to generate an associated plan view. A good example is the top of a parapet wall."

To change copied level to actual plan view, do the following:
"Adding a Plan View
...Go to View tab and under the Create panel, select Plan Views/Floor Plan. A dialog box opens that allows you to select a level and create a new floor plan based on that level. Check Do not duplicate existing views at the bottom of the dialog box. (This process is the same for ceiling plans.) The level symbol will then change to blue, indicating that it is a hyperlink to a plan view."


"Duplicating Views
...want to create a new view based on an existing floor plan? Say you already have a design plan of Level 1, but also need a presentation plan and a fully annotated plan for your documentation set. You can achieve this...by duplicating
views. ...right-click the view’s name in the Project Browser (Level 1 for
example), and choose Duplicate View from the context menu."

"three different ways to duplicate a view:
Duplicate - Makes a duplicated view in which only the model data of that view is copied. ...when you don’t wish to copy any tags, dimensions, or annotations from one view to the next. ...model is not copied — you’re just creating a duplicate view of the model without bringing along any 2D graphics.

Duplicate with Detailing - Makes a copy of the model data and any 2D information (such as text, dimensions, or keynotes) in the view. ...annotations and detailing that are added or edited in the original view after the duplication aren’t propagated
in the duplicated view. Only model-data modifications are propagated in the duplicated view. The copied annotations are not linked.

Duplicate as a Dependent - Not only creates a duplicate of all the model and drafting data, but also creates a dependency between the detailing information of the duplicate view and the original view. When this type of duplication is used, changes of both model (3D) and drafting (2D) elements in the original view will propagate in the duplicate view. A use case for this type of duplication would be a project with a big floor plate that you need to split into separate segments for printing."

NOTE: "Dependent views created with the third method (Duplicate as a Dependent) must always remain in the same scale as the original."


"Types of Views
Plans
Callouts (Enlarged Plan View)"

"Plans - ...To control how the plan is represented, a view range is defined."
View range settings control what you see beyond the cut plane. This applies only to floor and ceiling plans.
"View Range options ...influences the visibility and appearance of the elements in the plan or ceiling views of the project. To access ...right-click in the drawing area and choose View Properties, Edit (under Extents), View Range."

"The following list describes the Primary Range features in the View Range dialog box:
Top plane ...defines the uppermost plane above the cut plane up to which
elements will be considered. If an element is above the cut plane but still in the primary range (partially or fully), the element is visible in the plan view as if it were seen from below the element."

Cut plane ...defines the height at which the 3D elements of the model are physically cut."

"Bottom plane ...is coincident with the view depth plane, but it doesn’t have to be. If an element is below the cut plane and is wholly in the primary range, it’s still shown. Note that only a few Revit elements are considered here: windows, furniture
systems, and generic models."

"View depth ...defines the extent to which you want to view what is below the
cut plane."

"some Revit families are never cut. ...choose the Manage tab and click Project Settings, Settings, Object Styles. ...some elements are grayed out in the Cut column. These objects...are not affected by a change of cut height."

"Floor plans ...horizontal slices through the building and are associated with
levels. These views typically cut the model at 4′ (1.2 m) above the level line."

"Ceiling plans ...behave in a similar fashion to floor plans..."

"Site plans ...by default are at 1″-20′ (1:250) scale and are views from above your
model. The site plan typically shows the physical and topographic features of the model and doesn’t show certain annotations that normally would not appear at scales greater than 1⁄16″-1′ 0″ (1:200)."

"Area plans ...can be used for gross area, rentable, or Building Owners and
Managers Association (BOMA) area calculations, to name a few. To create one of these
types of plans, click the Home tab and under the Room and Area panel select Area and then Area Plan. Area plans are most effective when you have areas that span multiple rooms."

"Callout ...detail view that can be placed in plan, section, or elevation views. ...if you have a plan view...and you want to create another plan view that represents
only part...at a larger scale to show more detail, you use this command.
Callouts...show a larger-scale cutout of a view...dependent on the parent view from which it was placed. ...if the parent view is deleted, any callout view or views dependent on that parent view will also be deleted. ...two possible types of callout views for floor plans (as shown in the Type Selector when you select the Callout tool): Floor Plan and Detail View. ...the new callout will show up in the Project Browser..."

How to create a callout
(From Revit Help file)
1. In a project, click View tab, Create panel, Callout.
2. Click Callout tab, Element panel, and from the Type Selector, select the type of callout to create: a detail callout or a view callout (a callout view that has the same view type as the parent view).
3. On the Options Bar, for Scale, select a scale for the callout view.
4. To define the callout area, drag the cursor from the upper-left to the lower-right, creating a callout bubble as shown by the dashed line enclosing the upper-left corner of the grid.
5. To see the callout view, double-click the callout head to view

- Creating Views

"Creating Views
...best understood as live snapshots of the same 3D model taken from various vantage points.
...view types: plans, sections, elevations, schedule tables, lists, 3D views, and sheets.
...easily recognized and organized in the Project Browser.
...Right-clicking any view in the Project Browser lets you access the properties of that view.
...tools for view creation can be found under the View tab in the Ribbon."

"Navigating Between Views
...Double-clicking on the name of any view in the Project Browser opens that view in the drawing area and makes it active.
...An active view can be closed later using the Close button in the upper-right corner of the view. .this will not delete the view — it will just close it in the drawing area.
To delete a view, use the right-click menu when the mouse is over the view name in the Project Browser, or delete the view symbol (such as the section mark or elevation tag) in another view where the mark is available."

"...you can use view reference graphics, including section marks, elevation tags, and levels, as hyperlinks to navigate between views.
...double-click the arrow (in the case of elevations)or the flag (for sections and callouts) to open the view."
...hyperlinking of section and elevation tags via double-clicking works only when they are not selected or highlighted. If they’re selected (highlighted blue in Revit), no matter how many times you double-click, it won’t lead you to another view."
