Implement hem feature

[pierreporte]

Resolves #302

This is my first code contribution to the workbench. I’m not a programmer, I just know a little bit of Python. I’ve never worked on an existing code base before.

What is needed to do, as I see it now:

• When base feature is edited, the hem object breaks somehow
• Icon
• Task panel
• Add documentation for the math (basically it’s what I posted in Feature: Simple way to make hems #302)

What I don’t want to do with this PR:

• Improving support for miter
• Improving support for corner relief

@shaise SheetMetalCmd.py is very big. Do you think that SMWall and SMHem classes (and accessories) should be in a separate file each?

It’s exactly what I had in mind, thanks!

Though is this normal to have blue inside the bend?

[maxwxyz]

ah no, will correct it

@pierreporte
Nice!!
Yes, please put smHem in a separate file.
Also, is there a task panel for that?

Thanks @maxwxyz

@shaise There is no task panel yet. I will certainly need help for it. Now I need to get the math right because I want to change the width users will enter, then I’ll split the file and try to solve issues when editing the tree. The task panel should be the last one.

@pierreporte ,

No problem, do what you can, I will deal with the task panel.
