Wo ist der Fehler zu finden?
Wilfried oder A2plus?
Weder noch. Direktes bewegen der Teile mit Autosolving ist in A2plus nicht vorgesehen. Man muss dann halt den Solve button drücken.

Re: Beginner help with assembly of cupboard

Hi @_cyclops_, At first, you should have a look at this video: https://www.youtube.com/watch?v=vDcaFq6IEJM , for having a good introduction to A2plus. Assembly is show at the end of it. As the mentioned video is working with an older Version of A2plus, you should have later a look at this one, whic...

Re: Call for team! Reimplementing constraint solver

. Crosspost... Well, I don't think they can be joined, if the systems aren't decoupled. So, while it is possible, the usefullness is questionable. I assumed, that is what you wanted when you asked "Is it possible to calculate a placement operation for each constraint and then calculate an resulting ...

Re: Call for team! Reimplementing constraint solver

. Thank you for all the information. That is not how sketcher solver is working. Sketcher solver is a completely algebraic construct. Its job is to figure out a values for parameters, given a set of error functions, by zeroing out the error functions. It has no idea what is a placement, what is a ve...

Re: Call for team! Reimplementing constraint solver

The primary goal is to have a standalone solver decoupled from Sketcher, ready for 3d assembly solving, and with full python bindings. Hi @DeepSOIC, thank you for taking the initative and doing this call. My special respect to you... I am also not quite sure, whether a new stand alone solver will b...

Re: Another approach to assembly solver (A2plus)

Hi @GlouGlou, usually it is no good idea to mix up work with A2plus and other workbenches in one file. Problem 1 here: After cloning, the clone get's an independent (decoupled) placement of its original. If the original is moved, the clone is not. As the A2plus constraints are only operating at the...

Re: Adventure of fixing sketcher solver for large sketches

Back then when I tried to write a 3d solver for assemblies I failed for that very reason: standard numeric solvers are unable to cope with the fact that rotational and transitional degrees of freedom have different sensitivities, a unit change in the parameter leads to to massively different change...

Re: Another approach to assembly solver (A2plus)

I would like to know, if is it possible to add an assembly do with A2plus, to a body of Part Design, and then to use this assembly like a part of FreeCAD. My problem is to do and hole between all the assembly. Hi jbe, In standard mode this will probably cause problems. A2+ tries to generate solids....

Re: Assembly4 and TechDraw

This is the first time I've encountered a Part that has a Shape. Usually I hunt through the Group (and children) for objects with a Shape. Is this Shape added by Assembly4? Does it represent the whole assembly? Do "Model" objects always have a Shape? Is objectName == "Model" a reliable indicator th...
