Add a Masking Region to a Detail Family

When creating or modifying a detail component family, you can use masking regions to obscure lines in different views.

1. In the Family Editor, click Annotate tabDetail panel (Masking Region).
2. Click Modify | Create Masking Region Boundary tabSubcategory panel, and select a boundary line style from the Detail Items drop-down.
3. On the Properties palette, specify properties for the masking region:
   • Visible. Specify if the masking region is visible when the family is loaded into a project and placed in the drawing area.
   • Visibility/Graphics Overrides. Specify the detail levels at which the masking region is visible (coarse, medium, or fine).
4. Sketch the masking region (or regions).

   Masking region sketches must be closed loops.

5. When finished, click Finish Edit Mode.

For a sample detail family with a masking region applied, open the Nominal Cut Lumber-Section family, which resides in the following location:

%ALLUSERSPROFILE%\Autodesk\RLT 2021\Libraries\<language and locale>\Detail Items\Div 06 - Wood and Plastic\06110 - Wood Framing

After you add a masking region, you can sort the draw order.
