closest to you as you look at the view). When this option is not selected, the masking region
is drawn on the work plane on which it was sketched. For more information on using the
Draw in Foreground parameter, see
Masking Regions in Model Families on page 1148.
■ Visible . Specify whether 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).
5 Sketch the masking region (or regions). Masking region sketches must be closed loops.
For more information on sketching, see Sketching on page 303.
IMPORTANT If your model family only contains 2D elements (for example, a 2D toilet fixture) and
you want to apply a masking region to the 2D element, you must include an invisible line to represent
the Z dimension, which is where the masking region is drawn. The invisible line must be drawn above
the level and must be a minimal length (such as 1/8”) so that the masking region does not obscure
any other elements in the view.
6 When finished, click Finish Region.

IMPORTANT When a model family only contains 2D elements and you are adding a masking region
to a 2D element, you must include an invisible line to represent the Z dimension, which is where the
masking region is drawn. The invisible line must be drawn above the level and must be a minimal
length (such as 1/8”) so that the masking region does not obscure any other elements in the view.
11 Add any other 2D view representations (for example, front elevation and side elevation) and
masking regions, as necessary.
12 When finished, click on the Quick Access toolbar to save the family.
