  Hello guys,
  I would like to create a spider-web structure, I draw the web on Spaceclaim and set the SYS Share Topology to "Share".
  I set 12 fixed supports on the end of each line and a remote force on the center of the web. But I don't know why it is not working?
  I also watched this tutorial (https://www.youtube.com/watch?v=QF-NLcLZLFw), but does that mean I will have to add many Fixed Rotations to each lines?

  The error message indicates that you have free ROTX DOF. Can you try applying displacement instead of force?

  Hi,
  
  Thank you for your reply, I tried to use Displacement and put 0.00005m on z direction displacement on the center of the web. But it still show the error, could you help me with this?

  Hi
  I suppose you use shared topology so te beams share nodes at their common vertex?

  If not use that or use the merge nodes to merge nodes at their common vertex.

  Finally one way to check that all is connected use a modal analysis and that will show any disconnected lines/beams/nodes.
  
  All the best
