Summary0031708: HLRBRep_Algo hangs on certain models and produces out-of-bounds lines
DescriptionOn a certain model, HLR takes a long time (around 1 minute) and then produces an incorrect result with some edges stretching far outside model area.

On another model HLR hangs completely and never finishes (I am not therefore sure it is the same issue, but provide the model in case it helps the first issue).
Steps To ReproduceDraw[1]> pload ALL
Draw[2]> stepread UCDV2000X5CV.stp stp *
Draw[3]> vdisplay stp_1
Draw[4]> vviewparams -eye 0 -1 0 -at 0 0 0 -up 1 0 0 -scale 10
Draw[5]> vhlrtype algo
Draw[6]> vhlr on
--- this hangs for a minute then produces incorrect result

Draw[1]> pload ALL
Draw[2]> stepread assembly.stp asm *
Draw[3]> vdisplay asm_1
Draw[4]> vviewparams -up 0.26 0.96 0 -at 0 0 -60 -eye 0.96 -0.26 -60 -scale 3
Draw[5]> vhlrtype algo
Draw[6]> vhlr on
