Navigate to the add-in

To use the FORMlab Dimensionator Revit Add-In:
- Open a Revit Document.
- Navigate to the FORMlab tab.
- Click the Show/Hide button to toggle the Dimensionator panel. This panel can be docked anywhere in Revit or used as a floating window.
- If you do not have a valid license, a license window will pop up. If you're eligible for the free 30-day trial, the license will be automatically filled in.

Create Dimensions

Create one or more detail lines in a Floor Plan, Ceiling Plan, Elevation, or Section view.
Select the created detail line(s) and click Create Dimensions in the Dimensionator panel. This will generate dimension lines for each selected detail line.
Any element that intersected with a detail line and matched the configured filter will be dimensioned.

Adjust Settings

Customize the add-in's behaviour with the following settings:

Select created dimensions - Replace current selection with created dimensions.
Delete detail lines - Delete detail lines after dimensions were created.
Minimum wall width - Walls below this threshold will not be dimensioned. Fill in 0 to disable this feature.
Combine walls - Enable/disable to treat walls in proximity as a single element, dimensioning only the outermost sides.
Minimum wall distance - Walls closer than this threshold will be dimensioned as a whole when Combine walls is enabled.
Include elements in linked files - Will include elements in active linked files when enabled.
System Categories - Select which system categories should be included when dimensioning.
Generic Models - A generic model will be dimensioned if its IFC export category parameter is set to one of the below selections.

Verify Dimensions

Select one or more dimensions and click Select References to add all elements to your selection that the dimensions are attached to.
This allows for easy inspection/validation of the dimensions, regardless of whether they were created manually or with the add-in.
Tip: hide all unselected elements to make inspection easy and clear.
