Documentationn or explanation of the App::Document::recompute() function

Hello devs, I'm digging into the code and trying to understand what does the App::Document::recompute() function actually do and why it is so slow for my models. Came here from Assembly3 trying to create an assembly with moving part. Came to conclusion that a part with many-many holes in it will slo...

Re: Assembly3: Solver speed debug

Hi, Have you thought about freezing assemblies and sub-assemblies to gain speed? From all the parts there maybe 2-3 sub-assemblies with 4-5 parts in them (similar to bearings sub-assemblies), but I'm in doubt those are causing the delays. Besides that, the freeze option is very confusing... Logical...

Assembly3: Solver speed debug

Hi all and especially @realthunder, I wonder is someone invested work in debugging the solver speed recently. I tried to build an assembly for my project, for now it's a slider with some parts attached to it. As far as I understand the attachment is the "cheapest" computational constraint,...

Re: Assembly3: Pre-Alignment before Attachment constraint

[Sure if all holes are used that sounds complicated manually. maybe some tricks with a python script select the face, then add a LCS on each circle of the face. It will create hundreds of LCSs, which is not sane as well. Adding few major LCSs and offsetting is the only sane workflow I found usefull...

Re: Assembly3 preview

taking in account the simplicity of the part I would redo it in partdesign to get consistent constraints during assembly Want to stick to vendor's files as much as possible, there are too many of them to change. At the end I found the solution: I used the screw (on the bottom) faces to align SameOr...

Re: Assembly3: Pre-Alignment before Attachment constraint

5 - add offset attachment When do you add the attachment constraint? Before or after the coincident? Adding it after deleting the coincident moves the part... an alternative less-time-consuming-solution (not sure) is maybe asssembly4, for this case. once all the Lcs are in position, the part is in ...

Re: Assembly3 preview

Thanks! After playing with it for some time I guess there is no full circle on the wheels. When I select a side, only half of it is highlighted. But it gave me a direction to try PointOnLine for the bottoms wheels on one side. Since there is a bit of freedom between the wheel and the channel, I can'...

Re: Assembly3 preview

Which point do you mean?
I'm trying to align the point that exist on the radius of the wheel:

Assembly3: Pre-Alignment before Attachment constraint

Hi, The attachment constraint will probably be the most used function for my assemblies, but I find it hard to align the parts to the proper place with that constraint. Try attaching a part on a grid panel like the following in the proper place: 1.jpg I had thoughts that it will be great to use the ...

Re: Assembly3 preview

And additional question: How would you constrain the wheels like those: Screenshot from 2022-10-22 21-41-12.png On a channel like that: Screenshot from 2022-10-22 21-41-53.png I can't find a proper constraint that will allow movement between plane/line on the channel and a cylindrical parts of the w...
