Rise and Fall Symbols

In CADmep, you can use Rise and Fall Symbols to draw rectangular and round rise and fall symbols automatically on bends and sectioned straights in Model Space, Paper Space, or only in Sectional views.

Note: Rise/Drop symbols for fabrication elements in Revit are defined using the steps below and are reloaded into Revit during modeling. They are controlled independently of the Revit Rise Drop Symbols.

The Rise and Fall Symbols options are specified in the database as follows:

1. Click Edit Main Database Takeoff tab CAD Settings Display tab.

   The CADmep settings should now be visible.

2. In the Rise - Fall Symbols section, check the available options to show the Rise - Fall symbols in Model Space, Paper Space and Clipped Views.

   

   For more information on these settings, see the description of Display tab settings in CAD Settings.

Overriding and Enforcing Rise-Fall Symbols on Objects in a Model

The following example illustrates a duct ventilation rectangular and spiral straight item passing through a structural slab level.

Note: Any object with CADmep Service ranges can have Rise & Fall Symbols applied.

1. Select the CADmep straight for the object to become active.
2. Right click Rise-Fall Symbols > C1 End or C2 End.

   

3. To enable either End Connector (C1) or End Connector (C2), select C1 End or C2 End as required. The above example shows a duct ventilation rectangular and spiral straight item passing through a structural slab level end connector locations of C1 and C2.
4. To turn off the Rise and Fall Symbol, select Off.
