I could read it now.
I go thru your valuable tips, thanks.
As you said I have controlled the mates mostly using the PLANES.
I will explain more about my case now,
- Layout part (LAY.SLDPRT) having many reference planes to controll the TIE beams.
- tie beam (TIE.SLDPRT) length will vary for every insatance.
- In new assembly (ASSY.SLDASY) i have inserted the LAY first.
Cond 1: I need various instances of TIE part in ASSY with different lengths.
Cond 2: I don't like to have more than one TIE part file.
Cond 3: Lengths should in-context with the LAY dimensions in ASSY.
Hope this will helps to get deep in to my case.
