Loss of Expression in the Parameter box

[arfa]

Hello IronCad Community,

I have a little problem where when I drag the top cover from the catalog, I find that I lose the expression in the parameter box for that part, is it because my expression is wrong?

 

* Fyi , X put at X axis , Y put at Y Axis , and for the Top Cover please drag to the Y Pallet.
  For the Pallet base Handle , Length put value 1150 + (always 1050 ) to make it better and for the Width put value 1100 + ( 500 )

* The file below is a catalog file

Pallet.icc

That's all, thank you.

Parameters need to be self contained or they will be lost when placed in a catalog. Meaning, you are referring to Len/Wid that do not exist in the Top Cover Assembly. That is why they get the ???. You would need to use something like the Smart Attachment Points to Set that parameter on Drop to pick up a value from a different object on drop.
