| Summary | 0025829: Instability: bfuse produces bad shape on 32-bit and good on 64-bit | ||||||||||||
| Description | There is difference in results of tests on 32- and 64-bit Windows on current development version, the following tests are BAD on 32-bit and OK on 64-bit: bugs modalg_4 bug697_2 bug697_4 bug697_7 bug697_8 The difference is in result of bfuse command: on 54-bit it produces valid shape while on 32-bit it produces shape without some faces (see attached image) and checkshape reports "BRepCheck_BadOrientationOfSubshape" I run on i7-4790 CPU, 16 Gb RAM, Windows 7, vc10 SP1 | ||||||||||||

It's seems that there is a some problem with face-face intersector (inside BOPAlgo). I extracted two faces from initial shape - f1.brep + f2.brep. The following script can be used to reproduce this issue: restore f1.brep restore f2.brep bopcurve f1 f2 That script produce the following results: 32bit: Tolerance Reached=0.05492097931250408 2 curve(s) found. c_1 c_2 (out32.jpg) 64bit: Tolerance Reached=9.0623070963573101e-005 2 curve(s) found. c_1 c_2 (out64.jpg) |
