Hi @Klaus,
any news on Datum Plane in A2+?
Hi Maurice,
nothing new at moment. I am bound to some big projects at job and there will be not any time at all within next 2-3 month. I hope the situation will improve after that.

Greetings,
Klaus

Can the mates that fail be highlighted in the tree or perhaps a list of the mates be made so that we can easily see which mates we need to fix?
Hi Dan,
IMHO this is not possible. A2plus only detects numerical value divergation summed up over all constraints. So it is extremly difficult to say which constraint is failing.

Thanks for the response Kbwbe.

Bundle of thanks for all.
I am working on several CADs from last 19 years. In some CADs its never happened and in some others we need to redefine constraint and/or just re select the geometry associated with constraint.
I know you all working so hard to make FC workable and I appreciate your efforts. I am trying but I have to learn C++ and Python fist that I am failing to manage right now.
Let see what happened next.

I try to make datum points to use for constraints but those are not visible in a2plus. Even LCS are not visible. Any approach to create constraints that I can make features after that? I am starting a new project and want to use FC but Its required huge assembly. Any solution???

This is not possible yet and it requires a heavy rebuild of A2plus. So this will not come soon.

As told some post before: Activate the option "use experimental topological naming" within the preferences page. This reduces the number of broken constraints after applying new features to parts.

How big is your assembly going to be ? In the assembly below there are ~300 parts, in sub-assemblies and sub-sub-assembies, all positioned according to LCS:

My assembly will remains to 100 or 120 parts so far. I will try what you told me. What assembly WB you are using???

I am using it but no luck.
