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 ()"

Steps To Reproduce

execute DRAWEXE bulletShape.brep as follows:

wandererfan@huxley ~ $ occDraw.sh
OCCT DRAWEXE v7.3.0
Hint: use "pload ALL" command to load standard commands
Draw[1]> Draw[2]> pload ALL
1
Draw[3]> restore bulletShape.brep
bulletShape
Draw[4]> vinit
Driver1/Viewer1/View1
Draw[5]> vdisplay bulletShape
Draw[6]> vfront
Draw[7]> vfit
Draw[8]> vhlrtype algo
Draw[9]> vhlr on
Error: AIS_Shape::Compute() HLR Algorithm has failed ()

Draw[10]> vhlr off
Draw[11]> vhlrtype polyalgo
Draw[12]> vhlr on
Draw[13]> exit
OCCT DRAWEXE v7.3.0 finished
