Summary | 0029121: Iges-reader reads invalid shape | ||||||||||||
Description | Test de iges_1 R8 ffirst.bin attached file contains the face read before ShapeFix_Shape calling. Result shape (after fixshape) is res_1. Indeed, both shapes are invalid (at least, contain not-closed oriented - only FORWARD/REVERSED edges - wires). Finally, BRepTools_WireExplorer works incorrectly with the read face. The face res_1_364 contains 14 edges. But BRepTools_WireExplorer finds 6 ones only. | ||||||||||||
Steps To Reproduce | binrestore ffirst.bin test de iges_1 R8 explode res_1 f don res_1_364 fit vori res_1_364 # Maybe, some edges must be marked as INTERNAL or must not be read. However, we have only oriented edges. nbshapes res_1_364 # EDGE : 14 explode res_1_364 w # res_1_364_1 res_1_364_2 wexplo res_1_364_1 res_1_364 set n1 [llength [directory WEDGE_*]] # Remove all variables "WEDGE_*" foreach x [directory WEDGE_*] { unset $x } wexplo res_1_364_2 res_1_364 set n2 [llength [directory WEDGE_*]] puts [expr $n1+$n2] # 6 | ||||||||||||
