Hole and Sizing
Create Hole
If you choose to create a hole in your extrude, then you need to set additional parameters which define the thickness of your “wall” (see below).
Outer Diameter/Height
Outer Diameter/Height disabled means that the width and height (in the case of rectangular shape) define the inner figure and the thickness “wall” is added to that size.
Length/Diameter
If you chose a rectangular form, then this parameter is the height of the figure. If you chose a Circular form, it is the diameter of the circle.
Width
Width is only used to define the width in a rectangular form.
Thickness
Thickness is the “width” of the wall of your extruded object and is only a valid input parameter if you have Create Hole enabled.
