Is there a user guide manual for geometry modeling?

Hi, is there a user guide manual for geometry modeling? The example of the "How to geometry modeling" in the introduction manual of comsol multiphysics is simple and not enough.

That's a good question! It's straightforward enough to paste together geometric primitives, but when you get to best practices for creating global geometric entities, multiple instances, boolean combinations, adjustments like filleting and rounding, it would be nice to have simple examples, at least. The example library is great but it tends to be on the complex side, like the complicated comb structure from Steve Senturia's book.

I was creating structures with Sentaurus Structure Editor, which exports AutoCAD-compatible SAT files which can be imported with the CAD import module. This is nice if you're good with the Sentaurus Structure Editor, because it's script-driven and you can thus (if you can deal with ELK/SCHEME) do relatively complex structures like (in my example) a lumpy surface characterized by a particular autocorrelation function and randomized Fourier coefficients, but the parameterization provided by COMSOL's built-in structure model is really attractive for structure optimization.

Hello Gaoteng,
I would recommend Chapter 7 in the Reference Manual (page 371-479 in version 5.1 of that manual), accessed through File>Help>Documentation. It is quite detailed and includes examples.
Best regards,
Jeff
