Sheet Metal Workbench

PR https://github.com/shaise/FreeCAD_SheetMetal/pull/236

I updated the PR to include a "length specification" property. Not 100% sure how to deal with "Outer Sharp" and "Inner Sharp" and the "base" flange length. Would appreciate it if somebody could test it.

It seems more naturally to me to specify the radius in some parameter, and specify flange lengths ...

I completely agree. I hope that by putting some terms out there, and explaining how things are handled in other CAD, as well information on how this software is used in the industry, we can interest people and developers in implementing some of the things we'd like to see.

I like to define a radius and a leg length (I'm sitll not convinced that leg length is a correct term).
It is handy if you need the flat strip to have a certain length whatever radius you choose.

I think this is the designers' way to model.

The flange length approach is more for the manufacturer, but this can easily be extracted from a drawing.

For me it is no improvement to use the flange length with this tool.

I see a need for proper terms for sheet metal related task here, too. Feel free to further improve the descriptions of mainly non natives.

But I think it's less important to know how other programs handle things, unless you want to make FC a copy of program XY.

When will it be available via the Addon-Manager?

I think Shai Seger merged it already.

I think Shai Seger merged it already.

Therefore it should available right now, just re-update the workbench via the addon manager

It is available now.

Quick test gives different length for each length specification at 90°. I'll dig deeper when I find the time to update the wiki page.

I was afraid that the tool would change drastically, but now looking at the updated version I must say that I like how the new options were integrated.

This feature has to be revisited in the future I think. I'm not sure if all the permutations of "Bend Type" and "Length Spec" make that much sense. E.g. with "Outer Sharp", the flange length is from the outer sharp point, but the length of the base is not.

At the bottom of SheetMetal_Examples you can find this image now (plus a wee description):

Just had I look if I needed to document something onyl to find out that everything is done already. Thank you very much!
