Auto outline interior elevations
Interior elevation outlines are time-consuming to create, and require care when design changes, again and again. AutoCrop Revit® add-in takes care of creating and updating it in one click.
AutoCrop outlines interior elevations in Revit automatoically using filled regions or crop regions — with full configuration control and no manual drawing required. The addin sets the line style of the filled region if you use that method, so you can easily customize its appearance. It can also read geometry from linked models, and has a toggle to ignore linked models entirely if you prefer.
AutoCrop is a lightweight add-in that runs locally on your machine. It works with Revit 2021–2026, and is available for individual purchase or volume licensing.

Installing
Download the installer and run it. The installer supports per-machine installation. We used to support per-user install in older versions — if you still need it, let us know.
Configuration
A few configurations can be set via the installer by clicking the Advanced button, which opens a configuration dialog.

Method used to outline
The default outline method is empty, and the UI will display toggle buttons to switch between the two supported methods: Filled Region and Crop Region.
You can fix the method at installation time to deploy a uniform choice across all Revit installations. The add-in looks for partial matches of “filled” vs “crop” (case-insensitive). When a choice is set here, the toggle is hidden from users. Leave the box empty to let users switch freely.

You can reverse a fixed choice by editing the .config file in the add-in's installation directory. The config file persists across upgrades and reinstalls; uninstalling does not remove it.
Other configurations for the Filled Region method
Most customers use Filled Region, so additional customizations are available for that method. These take effect only when Filled Region is active.

- Filled Region Type Name — Specify a type name for the filled regions AutoCrop creates. If a type with that name doesn't exist, it will be created.
- Line Type Name — Specify the line type for the internal curve loop. If your team already uses a dedicated line type for this purpose, set that name here. Otherwise the add-in creates a new one using the weight below.
- Line Weight — Sets the line weight when the add-in must create a new line type. Has no effect if an existing line type is found by name.
