Thanks for the feedback!

> About sweep

This looks like a meshing problem - when MoI wants to display a surface, it creates a triangle mesh for it, and if it does not put enough triangles in it, it can look wrong like this. Right now this sometimes happens in shallow curved areas like you have there. If you can post the file, I will put it on my list of meshing problems. It will probably be a couple of months before this area is improved.

You can sometimes adjust the meshing parameters to improve this - under Options try checking "Add detail to inflections", or reduce surface angle slightly to maybe 7 or 8. But don't reduce it too much or everything will get too many polygons and stuff will start to slow down.


> About chamfer

I've added this to the next beta. In the next beta release, there will be a "Straight corners" option that you can check to get the style that you want.


> Extrude - Cap Start / Cap End

There is an easy way to remove just the start or end cap after you've done an extrude - just select that face and hit delete. Extrude already has quite a few different options in it, I sort of hesitate to add another option in it for something that is pretty easy to get just with delete...

Thanks,
