aiprenticeHow do you automate interior elevation outlines in Revit?
Use AutoCrop, a Revit add-in. In one click it outlines your interior elevations with a filled region or a crop region that follows the walls, floors, ceilings, and roofs each one cuts. When the design changes, run it again to update the outlines.

Why are interior elevation outlines so tedious?
Because Revit doesn’t trace them for you, and they go out of date every time the design changes.
- Revit crops a new interior elevation at the bottom of the floor rather than the top, so every one needs adjusting.
- A single project can have hundreds of interior elevations, each needing an outline drawn by hand.
- Users have asked for a fix since 2004. In an AUGI poll that year, over 90% of respondents wanted it in the next Revit release.
How does AutoCrop work?
It reads the geometry each interior elevation cuts and traces the outline for you, in one click.
- Outlines follow walls, floors, ceilings, roofs, sloped glazing, family instances, and in-place families.
- It reads linked models too, with a toggle to ignore them.
- Casework can be handled differently from other elements.
- Run it again after design changes, and it updates the outline instead of starting over.
Should you use a filled region or a crop region?
Most firms choose filled region, because it gives the most control over how the outline looks.
- Filled region: AutoCrop uses the filled region type and line type you name, creating them at your chosen line weight if they don’t exist yet.
- Crop region: AutoCrop shapes the view’s crop to the outline.
- Lock the method firm-wide at install, or let each user switch between the two.
What else in Revit drawing production can be automated?
Dimensioning checks, and documentation generated from the model itself.
- Dimension Assistant red-lines elements that aren’t located yet, in real time, so you can see how much dimensioning work remains.
- Artifact Build generates 2D views and completes construction documents directly from your Revit model.
What do BIM managers say?
Interior crop regions are never perfect! To make matters worse, as the design changes, the boundaries need to be updated to match. It’s a huge time waster.
