Excessive response times using transforms

[DrC]

Can I add a real life user experience of multi-transform please on the current Windows version?

It is attached. Even editing the transform parameters is excruciating. It's a tribute to Freecad that it's worth doing anyway because I love the way Freecad works, but I suspect there's something in the code that recomputes unnecessarily often.

Thanks for a fantastic product - I hope this helps you to make it even better.

Hi DrC, I've moved your post because you replied to a 5 year topic that doesn't seem to have anything to do with what you've posted. Please update the title at your convenience to something that makes sense.

Thanks for picking it up.

70 sec recompute here. There was some work to use multithreading for those transforms but still uses single core here.
It would be better and faster to model it in a single sketch.

Edit: sorry, forgot that version is relevant here

The version of FreeCAD that you show is old. It is 0.17 which was released early in 2018. You should try the newest version 0.18, which was released this year. There are improvements in the base system that will probably solve some issues.

Yes, that was performance-wise a regression in v0.17. There are a few threads where this was discussed. So, as the others said it's best to go to v0.18 where this is fixed.

There are 8x12 and 8x4 multitransform grids in that file. Changing length of MultiTransform001.LinearPattern002 from 63 to 64 and recomputing took 65 sec here so dont think that unneeded recomputes is the problem here.

Thanks - I missed the notification of 0.18 so it's downloading now.

Cheers
