You can also link each extrusion to a condition [Condition].

Possible characters include &, |, !=, =, >, <, >=, and <=.

Example: The sketch should only be extruded if the variable H (Height) is set to a value greater than or equal to 10 .

Design steps (features) that are excluded based on the condition are displayed asdeactivated (grayed out) in the 3D history [3D History] and indicated by an "IF" next to the icon.
