Hi, I attempted to assemble some aluminum profiles created using Maker Workbench. I converted them into A2plus parts and tried to apply the Add planecoinsident constraint. However, I encountered the following error: The highlighted parts were not moved. They are not constrained (also over constraint chains) to a fixed part!. So I searched online and found(From here):

A2plus is designed to import parts, each one been designed in a separate file. If you import your single parts into a assemby file, you can apply constraints and this will work.

I also tried to set fixed Position to true, but only the warning window disappeared, the aluminum profiles still didn't move.

What's the difference between the part that was converted and the part that was imported? Can we fix that?
