We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi David,

It appears that the ends of your beams are not sharing a node. Please check if this helps: Once you have created all the line bodies in SpaceClaim, highlight selected parts under the part tree, right-click and select Move to New Component. After specifying a cross-section for the line bodies (in the Prepare tab), go to the Workbench tab, and select the Share object. The nodes at the coincident regions should be merged (shared topology).

You can also try creating Bonded contact within Mechanical but you may try the approach above first.
