Thanks for this, Brian! I was tearing my hair out trying to figure out how to do a countersink in a hole. I'm still playing with the MoI demo (I really love this CAD software btw). I hope the developer of MoI (Michael) makes this into a proper feature in the new version as MoI is an excellent alternative to many of the other offerings available. Or perhaps someone would be so kind as to write a script that would do a countersink in a hole.

If you have a bunch to do then make a tool that cuts the hole and countersink in one shot using Boolean > Diff

Hi There

if a hole is too close to a side edge it will often not chamfer as the left block

using a cutting solid will also cut the edge out

cheers

Hi shayno.
Try using the ACIS option for chamfers in V5 - it seems to work just the same as boolean difference.

MOI isn't very intuitive for holes when you first start using it, especially if you've moved from a CAD environment

If you want to drill a partial depth hole then you can use extrude/bothsides to your correct depth and boolean it out

ado1, I trained using Solidworks, and tbd, MoI3D comes pretty close in terms of workflow. Sure, there are differences of course, as Solidworks, at least the 2001 version of SW, is a full-on industrial/mechanical CAD experience. But the overall feel of MoI3D is more Solidworks than say, Cheetah3D. I love how MoI3D is very precise when using measurements. Few other 'modelling' CAD's offer that on a budget. It's brilliant that Michael Gibson is still after all these years supporting MoI3D, and because of I'll probably buy a copy as soon as I get paid.

But back to the countersinks, thanks to all about the chamfer. I initially tried that but it didn't work. But now I understand why.
