  Add a Modal analysis to your Model cell. Drag and drop the Fixed Support on the Modal analysis. You will find that the lines are not all connected.nGo back to SpaceClaim and use Shared Topology to connect the beams together.nAnother way to do this is to Insert a Node Merge Group and merge the coincident nodes to connect the beam.nn

  nYes, each line can have its own profile using either method.nThere are many free courses under the Courses section at the top of this page.n
