I have an orphan mesh consisting of mainly 2D CQUAD elements and a few CBEAM elements.
I want to create a geometry from mesh which I can export so that it can be read inside a CAD package.
I am aware of the Femap's Surface->From Mesh function. Trouble is, its giving me errors. Not sure what to do next.
Create Surface From Mesh 554 Element(s) Selected... UnAssociated Nodes and Elements No geometry associated with 394 Nodes. No Geometry associated with 454 Elements.
I see no surfaces created. Please help me resolve this issue.
The command "Geometry > Surface > From Mesh" runs OK if you select the mesh by patches, not full. It is best to select elements that will create a single surface instead of selecting all of the elements in the model. It is also better to select only one half of any “closed boundary” (for example, a cylindrical shape), instead of trying to have it create a surface all at once.
But if command fails is very easy to recreate geometry manually: simply use nodes as keypoints for the geometry, for instance:
Attached is an API I created to help stream line creating surface from mesh. When the API is run for the first time, it will initilize a face picking dialog with a low tolerance. For best results, use this tool for surfaces that are not highly curved. With this API, you can create surfaces from ANY type of element, not just shells. There are also some geometry extrusion options included to help jump between creation and modificaton.
