| Summary | 0027033: Modeling -- ensure stable result of area calculation | ||||
| Description | The results of sprops command are unstable on some shapes, yielding different values from time to time for exactly the same shape. This should be fixed so that results are always the same. Note that similar problem has been reported in 0025945, but in that issue the differences were explained by differences in argument shapes (tolerances). The instability has been discovered on shape produced during test bugs step bug11856 | ||||
| Steps To Reproduce | pload TOPTEST XDE stepread [locate_data_file OCC11856.stp] a * ;# just to generate shape, too large to attach here # "sprops result -eps 0.1" in most cases yields 611185, but sometimes (about 1 per 10 runs) 61173, 577943, or other for {set i 1} {$i < 1000} {incr i} {checkprops result -s 611185 -eps 0.1} | ||||
