remus (esaueng)VerificationConfidence: Medium

The Remus STEP writer wrapped every non-line edge in a TRIMMED_CURVE, which ISO 10303-42 advanced B-reps don't allow; FreeCAD 1.1 imported a Remus cylinder with 0-edge caps, bounds of plus or minus 1e100, and solid volume 0, so every export with circles or splines was affected. Remus's own round-trip test only read the file back with Remus, so nothing caught it.
