Hi Tom. I may have done something here but I do not recall what or where it is.  
@prochazkao, here’s a screen grab of your part. Can you more or less sketch your desired leading edge on part of the image and I’ll give it a go.

Holy crap. I’ve been too busy with other stuff. When did they add “draft angle”? And is it in percentage too?

It’s been part of the ‘extrude’ function for some time and it is plus/minus angle only (no percentage).
