Threads in TechDraw

Postby Michael_HH » Fri Oct 16, 2020 4:53 pm

I found the Last entriss concerning ISO thread visualization from March 2020. Are there any news
or easy way how to do this?
What will be perfect will be an option to mark the hole (top view) or rectanguar field (cut view)
and mark it as thread. In such case the correct marking should be inserted similar to a simple middle
line, that can already be inserted.

Hello @Michael_HH per our guidelines please remove your FC version info from your signature. It will be confusing for posterity if you keep it the same or alter it. Thank you for your comprehension.

Edit:
also if you choose to run v0.19 please keep up to date with it (you are using an old revision of 0.19)

I started with a macro: https://forum.freecadweb.org/viewtopic. ... ds#p397091

however the hard part is still to link the information from PD into TD...

@reox
Thank you very much for the posted link to the created macro.
It was completely new for me, that you apparently already started im May working on a solution for thread representation in TD.

I tried the macro on a simple cube with tapped hole and as far as I understood the functionality, according to current state it creates the correct thread representation according to ISO 6410-1 in TD for the top view. I think this is a very huge and considerable progress in solving the thread representation issue in TD.

The thread representation in the cross section is not developed yet. Especially the representation of a partial thread will be a challenge for development.

Unfortunately I read also in the TD forum about the absence of Developer Wandererfan absence for the foreseeable future https://forum.freecadweb.org/viewtopic.php?f=8&t=51233. :cry:

In your last thread posting you wrote

I also believe that it will not be easy, although I cannot really evaluate this. My current Python programming skills are rather poor. :cry:
But that need not to remain so...
Maybe for a final stage the implementation in PartDesign workbench feature hole https://wiki.freecadweb.org/PartDesign_Hole
will be a very distant goal...
How could one perhaps support you and your efforts?

Kind regards
