Need help on A2Plus
I have been Doing some assembly on A2plus, and I am hitting roadblocks.
1. I make corrections on the Part while it is inserted in assembly, and when i hit refresh in A2plus the part scrambles and after that i cannot insert any part as it gives out this message : Constraints Inconsistant. Cannot solve system. Please delete your last created constraint!.
I checked but no constraint has been there in any part of insertion, can you help me please to solve this.
Rgds,
Ash.

Re: Need help on A2Plus
Hello, there's a thread called Assembly that raises questions of this kind. See https://forum.freecadweb.org/viewforum.php?f=20
Tip, update A2Plus (0.2.4) from Addons Manager and start using FreeCAD version 0.18 from here https://github.com/FreeCAD/FreeCAD/releases as it will be available very soon.
In the latest version of A2Plus, when you remove a part, the restrictions on other parts on which it depends are removed. It also has icons with functions to see the restrictions that are causing the problem.
Greetings

probably you are facing the topological naming problem of FreeCAD.
After editing a part, the numbers of vertexes/edges/faces often get mixed up by FC. This can lead to constraints which refer to wrong geometry and the system gets not solvable.
In your case, i would try to delete all constraints of the part, which has been edited. (select the part and hit the button with the red X)
After doing this, the message "System not solvable" should disappear.
Now you have to constraint this part newly again.

This is how the page looks
Re: Need help on A2Plus
Hi Ash,
in newer A2p versions, the constraint buttons are selection sensitive. Select what you want to constraint, then appropiate buttons geht activated. Please see screenshot:
