Another approach to assembly solver (A2plus)

[Jee-Bee]

I like to follow this topic!!
Keep up the good work. Great to see another assembly tool in FC

Your nr. 5) idea, what I think you mean works the same in SolidWorks ('Width'): http://help.solidworks.com/2017/english ... SWassy.htm

Yes it is

Hi Klaus,
please just don't feel any time pressure!
Like @Turro75 said yesterday or so,
"it's ready, when it's ready." Period.
I like him for this expression!

Hi Manuel,
the recompute issue is fixed, your icon for DOF printouts is within the toolbar.

this is working if I switch the WB to A2p before opening the FC file.
If I open it without having loaded A2p WB before, the icons are not displayed.

I get the same result:

Our resources are loaded in InitGui.py so they are not available until A2p is initialized. Maybe there is a better place to put the Resources?

Hi all,
issue is now really fixed. The ressource-files are now imported instantly at head of InitGui.py. I now can see the correct icons even when other WB is activated and A2plus has not been started before.

For tests, you have to update your A2Plus files from github. (master or devel)

Edit: Please test with the file attached...

Hi Klaus,
thank you for your work... But can you please check your latest commit for the recompute issue? After editing the first angledPlanes constraint (from 0° to 120°) after inserting in my crankshaft I get the following Error:

Code: Select all

Traceback (most recent call last):
  File "/home/manuel/.FreeCAD/Mod/A2plus/a2p_viewProviderProxies.py", line 253, in execute
    self.callSolveConstraints()
  File "/home/manuel/.FreeCAD/Mod/A2plus/a2p_viewProviderProxies.py", line 282, in callSolveConstraints
    autoSolveConstraints( FreeCAD.activeDocument(), cache = None )
  File "/home/manuel/.FreeCAD/Mod/A2plus/a2p_solversystem.py", line 554, in autoSolveConstraints
    FreeCAD.activeDocument().recompute() # perhaps a constraint was inserted or edited

Thanks!

Hi Manuel,

I faced the same, this happens because the value changes from 0 to 1 to 12 to 120, so with autosolve active there are "overlapped" solving processes which leads in multiple recomputes.

Maybe the autosolve could be optimized in a way to avoid multiple solving and /or a filter of some seconds letting the editing completed.

Oh, then I need to add, that I had "autosolve" off!

AND EDIT:
...and that the part doesn't get rotated although the value is in.

Hi Turro, hi Manuel
i am working on this topic. The nested recomputes are more complicated than i thougt. Tomorrow i have more time, i hope that there will be a solution!

Just nice to read that you're working on it.

On here, btw, formerly just a click on FC recompute did the job. But one needs to do it each time, from time to time.

You'd get it!

Hi Manuel,
i just committed my last work and switched back to old recompute strategy. (Manually to do from time to time)
Some small things changed towards going to release...
- New button to create visual hierarchy. Automatic mode was messing my disk with not needed files... (We need a better icon)
- several new message boxes if user is doing something wrong (what leads to a lot of error printouts)

Mainly, it should work as before.
