Convert CGR to STP

QUICK ANSWER
Is it possible to convert CGR to STP?
Yes - CGR converts to STP.

Possible but limited: converters can wrap the CGR mesh into a STEP file, but because a CGR holds only tessellated graphics (no exact B-rep surfaces), the result is mesh-quality geometry, not precise solids. Good enough for visualization, not for parametric editing.
