3. Open the Family Types dialog box, and for Type 2, set the Trigger Cut value to 0’-0” and
then click Apply.

4. Switch to Type 1 and set the Trigger Cut value to –0’-4” (–100 mm), and then click OK
to close the dialog box. Figure 14.36 shows the difference between the two types just
defined.

You’ll see that adding the negative value to the Horizontal Profile Offset allows you to control
whether the void cuts the solid tabletop. We simply assigned the offset value to each family
type, but you could explore methods of using formulas with logic such as this:
If Tabletop Thickness < 4” then Trigger Cut = –4” else Trigger Cut = 0”

The actual syntax of this formula to be applied in the Family Types dialog box would be:
if(Tabletop Thickness < 0’ 4”, -0’ 4”, 0’).

Creating a revolve
Let’s move on to the process of creating the legs for the table. You’ll use the Revolve tool to
create this shape; however, you will create the shape only once in a separate family that will be
loaded into the table family and placed multiple times.
