Controlling Where Masking Regions are Drawn in Model Families
Where a masking region is drawn depends on where it is sketched in the family and the status of the Draw
in Foreground parameter. It is also important to consider other families with which the family may interact
as you determine where you want the masking region drawn. The following scenarios illustrate sample
families and the placement of their masking regions.
Scenario 1
The following images show a chair family and a table family, both with their masking region (red, dashed
line) sketched on the reference level. In the first image, the Draw in Foreground parameter is selected for
both the table and the chair. The chair masks the table, because the chair back is higher than the table.
In the second image, the Draw in Foreground parameter is cleared for the chair so that the masking region
is drawn where it was sketched. The Draw in Foreground parameter is still selected for the table. Therefore,
the table masks the chair.
Scenario 2
The following images also show the same chair and table families, but the masking regions are sketched on
different work planes. In the first image, the Draw in Foreground parameter is selected for both the table
and the chair. Again, the chair masks the table, because the chair back is higher than the table.
