Reply To: Need help with understanding meshing procedures

[peteroznewman]

The spars and ribs should be surface geometry, not solid geometry. Use the SpaceClaim Midsurface tool to create surface geometry from the solid geometry. Some cleanup may be required since the hole in the rib will be larger than the midsurface on the spar, but SpaceClaim has ways to extend edges to close gaps. Then you can use the Share button and meshing will be easy in Mechanical.
