Managing solid geometry

MishalMishal
Hi Guys

With regard to the use of surface geometry it is pretty easy to modify thicknesses to perform iterations on designs.
However, when it comes to solid geometry, how are you guys managing the models?

Say there is a plate and the thickness needs to be increased, since Mecway does not link to a modelling interface directly (like Discovery from Ansys) you need to modify this on your CAD model and then basically rebuild a new model. Have I lost the plot or is there an easier way to manage this?

    I do this a lot. Just make the change in my CAD files, export a new STEP file and update the reference in Mecway. If it is a small change like a dimension or a move face command, that doesn't change the topology or number of faces of the model, the ID of the faces should be the same and any assignments of loads and boundary conditions will still be the correct place after meshing the new file. The ID of the face is not an explicitly assigned identification number but is just the order that they are listed in the STEP file. STEP files are clear-text readable, if you open it in notepad. Try it with a simple cube to get an idea of what a STEP file looks like.
    If you have added faces or deleted features, then the algorithm for STEP file export in your CAD program may define the faces in a different order than before, so then you have to reselect the faces for boundary conditions and loads after importing the STEP file to Mecway.
