Figure 19.38 Creating a Yes/No visibility parameter
7. Select the extrusion created for the pad. In the Properties palette, click
the small box at the far right of the Visible parameter and associate the
parameter to the Pad parameter created in step 6; see Figure 19.39 .
Click OK.

8. Open the Ref. Level view. Create a vertical reference plane 4″ (100 mm)
to the right of the Center (Left/Right) vertical plane. Create another
vertical plane 4″ (100 mm) to the left of the vertical reference line
drawn in step 2. Create a horizontal reference plane 4″ (100 mm) above
the Center (Front/Back) horizontal plane and another one 4″ (100 mm)
below the horizontal reference line drawn in step 2, as shown in Figure
19.40 .
You'll notice that in this step we broke a few rules. However, those rules
will be more important from a consistency standpoint and for families
that are having connectors that are hosted on the reference planes. If
you are making such a family, you should consider keeping the Center
(Left/Right) reference plane as is and creating two reference planes
(one to the left and one to the right) for the UnitLength. This way, the
name Center (Left/Right) will actually represent the reality.
