Re: How can I add a bolt from Fasteners workbench in script?

Re: Fasteners Workbench thread and head scaling

Frank, Thank you for the kind words, but the big thanks are for Ulrich1a - he made the screws, I just organized it in a workbench. The screw-tap profile is made specially for inner threads, it can not be used as an outside thread (the profile is different - the ends are rounded rather then flat) So ...

Re: Fasteners Workbench thread and head scaling

Where do i find out how to do a tool with a counterpart?

When using the 3D printed mode, this "...

after I run it, there was no error hint, so it should run well, but nothing is displayed on the screen, could you please give me some more advise?

Add the following line:

Code: Select all

Part.show(NURBS_Cubic_surf.toShape())

jaisejames,

can you please look into issue #89 on sheetmetal. It looks like there is a problem: When you set a gap of X mm, you get a gap of 2X mm. It looks like the miter function returns the gap doubled
