Hi all,
I am having issues trying to assemble these two parts. Basically trying to constrain the hinge part to the wall bracket using the PlaneCoincident and the wall bracket is locked. Any experts that could have a look and let me know if I am doing something wrong
thanks Andrew

Haven't downloaded your file but ..... using one of asm3 mover tools move the hinge part as close as possible to the wall bracket while still leaving space to select the intended matching geometry. This will help the solver figure out your intentions.

If those two components are to be bolted together (0 degrees of freedom between them), it is advisable to use the asm3 attachment constraint as it saves on computational time.

Select first the the edge on the geometry that is already fixed in some way then the edge on the geometry that needs to snap in to place then hit the attachment constraint. The geometry should snap in to place. If it is rotated wrong expand the "attachment" entry in the tree view -> select (usually) the second "element" then EITHER right click on it -> flip element .....OR using the properties tab manipulate its rotation by changing the angle value.

In this simple case that should work. Let us know if it solved your problem.

this is the solution,
Hope it was helpful. It is so late, but I just passed away and find your post. Looks like you are familiar with SW. You made the assembly with the same logic of SW. Just Think FreeCAD, and you will feel the power of CAD.
I just removed the last constraint that you made. and moved the hinge part near to the hole of Wall.

Have a nice day.
