"Extrude Cut" in DesignModeler 12.1

[zephyrus17]

I come from Pro/E and Solidworks usage. And making an extrusion cut is easy but I just can't find this option in DesignModeler 12.1.

For example, I want to cut a cylindrical hole halfway through a bigger cylinder. I draw the bigger cylinder then click generate. Then when I try to draw another smaller cicle concentric to the cylinder on the same plane, it automatically cuts a hole through the entire cylinder.

I know I can just draw it out then revolve it, but I just want to dig a hole.

So what am I doing wrong?

You'll need to (1) make a new sketch on the starting plane, (2) draw your circle for the hole cross section and (3) extrude as a cut (Select 'cut material' instead of 'add material')

Yeah.. I do that. but it just extrudes the central hole all the way.

Here's the result that I keep getting in the link. Either it leaves the outer part alone, or it takes out the outer part. But the inner part is always extruded through all.

Belay that. It turns out that after you click generate to make the main cylinder, any 'new' sketches don't count as 'new' so it's including the old sketch with the cut. I've just had to click the "New Sketch" button. Thanks for the help, MrMyers.

Issues solved.
