Frequently Asked Questions (FAQ)

Posted by in CGM

How do I build CGM from scratch? I get warnings about “Attribute type -1 not recognized”? CGM has a “geometry attributes” capability which allows applications to define their own attributes, and write those attributes to the geometric model when the model is saved to a file. Attribute types are registered with the attribute manager upon instantiation of CGM, and are...

Prerequisites: Since CGM is mostly just an interface to various geometry engines, you’ll need one of those engines for CGM to use. There are various options: * Facet-engine: CGM is distributed natively with a Facet-based geometry engine that can be used to reconstruct a continuous geometry from faceted surface mesh representations. While such a mechanism may not yield very accurate...

What is CGM ?

Posted by in CGM

The Common Geometry Module (CGM) is a code library which provides geometry functionality used for mesh generation and other applications. This functionality includes that commonly found in solid modeling engines, like geometry creation, query and modification; CGMA also includes capabilities not commonly found in solid modeling engines, like geometry decomposition tools and support for shared...
