Drag Chain model problems

John Wayman Oct 1, 2018 10:10 AM

I am trying to model a drag chain that moves with the assembly it is mated to using the chain mate.

I followed the instructions in the Youtube video SOLIDWORKS 2015 - Chain Component Pattern - YouTube

I can get the chain to work if I select the Distance Method for Pitch, but, if I select either Distance Linkage or Connected Linkage, all the instances of the chain links pile on top of each other.

What am I doing wrong?

Assembly model is attached.

SW2018, SP4

I have tried lots of times, with different options, and even starting again from scratch, but I am coming to the conclusion that this must be a bug.
I can't see why it shouldn't work.

  Hi.
  Take look at this (attachement). I think that you have done some errors when matting components.

    I must say that I also was confused about this pattern function. The pattern function also acts as a mate upon the to be patterned part, seemed strange at first; on second thought more or less logical though.
    
    Never used this pattern function in real life though. Will give it more time when a design challenge rears its a head :-)
    
    Nice find Krzystof!

    Thanks, Krzystof.
    
    It's still not obvious, but at least I can get it to work now!
