To calculate weights, you must have previously meshed a model. The mesh name appears on the project tree on the left side of the screen, as shown below:
To perform a weight calculation, highlight the mesh name and select Mesh…Weights. The following window will appear:
Note: To obtain a highly accurate weight estimate for a casting, you can create a mesh with no mold material and a high number of nodes. This may often be the first step in developing a cost estimate for a casting. Once you have gotten the weight information, you can delete the mesh to save space on the hard drive.
