Re: Multibody Part: Unknown C++ exeption when saving

OK, I found 1 workaround: To model the other part in a separate file and then copy&paste it into the target file. Then there are no troubles.

I am still interested in comments regarding a proper recommended procedure.

Multibody Part: Unknown C++ exeption when saving

Hello, this is related to development version 0.17 and it's new topology. Perhaps I am doing something incorrectly with my attempts of multibody part. The reason for a multibody part is, that I need to process it with FEM later and it should be easier to model it in one part, do a boolean fusion and...

Applying force to portion of surface

Hi, I would like to know, what's the best practice/trick/workaround for applying a force only to a portion of the surface area of the part . It is easy to apply the force to whole surface area of a selected face and works great. However, what I need (and is needed quite often in general), is to appl...

Re: Assembly3 preview

@RealThunder: There's one thing I came across during the testing lately, it's the naming of the constraints. They're all grouped in 1 folder and have generic names (like PlaneCoincident1). Very soon one gets lost in the names, even with small assemblies, and all the time searches for the right const...

Re: Assembly3 preview

Yes that would definitely explain the results i am getting. When using most of "the standard" relations. I had a feeling SolveSpace shouldn't have an issue with robustness to such extent. PlaneAlignment is a composite constraint and it removes 3 DOF. When used on a two cube example above. When addi...

Re: color scale with the values is missing

- select the result object in tree view - Menue Results --> Post pipeline from result --> new object pipeline in tree view - double click on new object in tree view --> mode surface --> field displacement - double clicke on the scale to change values - you should enable back light in FreeCADs displ...

Re: color scale with the values is missing

...and it works there. I don't think it's the "user-friendliness" issue you've described, it simply doesn't work on that other machine and build. Strange enough, it's apparently the same build 0.17.13408 (but W7 vs W10). I never heard someone had that problem. Just to be sure it really is some prob...

Re: Assembly3 preview

asm3 composite constraints are actually modeled after Assembly2. In asm3, this plane-plane constraint is called PlaneAlignment. I originally wanted to use Assembly2's solver, so I checked its code. It is a while back, but I do remember that it is doing similar thing like I described, that is, to ke...
