In the process of doing some research into model and symbolic graphic representation, and the various methods Revit uses to control these, I came across a feature I had forgotten about. As I refreshed my memory I thought I would share the details with you our readers since its a rather involved and obscure feature.
First the "Override Cut Line Styles" feature is located in the Visibility Graphics dialog. Since it is located here all changes are view specific.
Here you can set some controls on how Cut Edges in Host layers appear in views that cut the model (plan and section). The check box enables the behavior and the Edit... opens the Host Layer Lines Styles dialog where you can set the appearance:
The "Hosts" in the dialog title refers to walls, roofs, floors, and ceilings. These element types all have layers and each layer has an associated function. Here are some layers and their functions in the wall Type dialog:
- Select Wall
- Edit Type
- Click "Edit..." in the Structure row of the Construction group
Back in the Host Layer Lines Styles dialog you can assign line weight, color, and pattern to each of the layer functions (Structure, Substrate, Thermal/Air, ect...)
"Common Edges" refers to a line that is displayed between two host layers of differing functions. The example below comes from the wall type "Exterior - Brick and CMU on MTL. Stud".
Core Layer Cleanup
...back in the Host Layer Line Styles dialog there is a drop down at the bottom to control Core layer cleanup. This only affect the graphics where core layers come together - typically just a small line at the core boundary.
You can choose from the following Core Layer Clean-up options.
- Default. This is the current behavior.
- Use Function - Sets the style of the separating line based on the layers' functional priorities. The style of a separating line is determined by the layer of the two with the higher functional priority.
- Use Common Edge Style - Ignores the functional priorities and material settings, and always uses the "Common Edge" style.
- No Edge - Sets the separating line to invisible whenever the layers have the same fill pattern
Here is an image where "Core layer cleanup" is set to "No Edge":
Finally, here is an image that shows how the various parts come together:
- All the Non Common Edges are set to be blue in the Host Layer Line Styles dialog.
- The Common Edges for walls are set to be red in the Object styles dialog.
- The core layer cleanup is set to use the Common Edge style and so that boundary also appears red. If it were set to No edge it would be absent.
After looking at all this I have to admit its very obscure and involved. I'm curious to know who is using this and how specifically? Where are you located? Is it satisfying your needs?
