Hi Guys,

I am not able to assemble any part with reference to the Assembly reference planes. The assembly reference planes do not get highlighted for selection when I try to assemble any part with reference to them (e.g. Mate or Planar Align). However I am able to assemble the first part in the assembly, taking assembly planes as reference. Please let me know if there is any option settings to be done to enable assembling any part with respect to the assembly reference planes.
