Spreading your factical wrong opinion around, to work unparametric in a parametric CAD, does not help, it just confuses new users.thomas-neemann wrote: ↑Sat Apr 01, 2023 11:54 am that's right, it's just meant to show a quick (non-parametric) alternative

Re: What makes this model so slow?
if @euphi77 wishes, i can try to rebuild his model in partdesign in this quick method
Re: What makes this model so slow?
One of the show stoppers is "Pocket - Counterpart001":
When I remove it, the recompute time sinks from 100s to 2. The problem seems to come from the (some?) tangents. I replaced some of them with a 1° angle and it works well now. Further investigation should include:
- is it really the tangent
- how small can the angle be (now 1°)
I attach the file 2.FCStd; its name comes from teh time to recompute.

Re: What makes this model so slow?
indeed...
There is malformed constraint(14) in Sketch027
deleting constraint(14) moves the issue to Sketch030 which shows overconstrained (9,10)
deleting (9,10) moves the issue to Sketch-Counterpart which shows malformed constraints(73)
and it carries on
Re: What makes this model so slow?
Thanks for taking your time. Removing the unecessary datum plane and attaching the "Height T-RGB" datum plane to XY_Plane speeds up things again. It still takes some time, but at least it's usable againimm wrote: ↑Sat Apr 01, 2023 11:39 am 1. Turn off 'Boden002' Body. (space bar to hide)
2. Expand Deckel Body.
3. Go to Part Workbench.
4. Select Aussenform in your Model tree. Go to Part | Check Geometry. It will check OK.
5. Work your way down through the other objects. You start to see problems at Box - akku.
The problems relate to the way you are using datum planes, especially the definition of their 'support'.
By linking the datum plane support to faces in your model you are bound to have issues with TNP.
To avoid this create datum planes that are not linked to any object at the support level. You can still change their placement using formulas.
As shown below.
I will also have a look at the "Counterpart" Sketch later this afternoon (as stated in other posts that the sketch solves very slowly).
What I still don't get is why recomputing took so long (and still takes ~ 10 seconds) even if I change features that are "last". All the previous features/sketches don't need a recompute?
Re: What makes this model so slow?
There are several "holes" that are threaded. Unless you intend to use the model file directly for some sort of CAM operation (3D printing, milling, etc) it is faster to leave the threads out.

Re: What makes this model so slow?
It is slow on Body Deckel on Pocket014. There is a Pocket in a seam. Per se not bad, but the seam is invalid. It is created due Pocket - Schalterbohrung. Could be a OCCT bug, but this must be verified a MWE.
The second slowdown comes from Pad - Ausparung Gegenpart. From them the Shapebinder imported shape, that pad gets almost co-tangential, known for that it can take long and can fail (as other suggested, there are better and faster ways to model it).
