| Summary | 0030961: HLRBRep_Algo/HLRBRep_HLRToShape return empty compound | ||||
| Description | Valid shape produces empty result when passed through HLRBREP_Algo. Same shape produces good result when passed through HLRBRep_PolyAlgo. DRAWEXE fails with message "Error: AIS_Shape::Compute() HLR Algorithm has failed ()" | ||||
