| Summary | 0033570: Modeling Algorithms - Incorrect result of cutting spheres | ||||
| Description | I found there might be a problem of the BRepAlgoAPI_Cut algorithm. For 2 spheres,s1 and s2: s1=BRepPrimAPI_MakeSphere(gp_Pnt(0,5.5,18),4.0).Shape() s2=BRepPrimAPI_MakeSphere(gp_Pnt(0,4.5,14),1.0).Shape() as shown in pict1. when I cut the s2 from s1 using the BRepAlgoAPI_Cut and got the shape s3: s3=BRepAlgoAPI_Cut(s1,s2).Shape() The result is shown in pict2. It seems the result is wrong. But when I change the radius of sphere s2 from 1.0 to 0.99, I got the right shape as shown in pict3. | ||||
| Steps To Reproduce | psphere s1 4 psphere s2 1 ttranslate s1 0 5.5 18 ttranslate s2 0 4.5 14 bcut result s1 s2 | ||||

Incorrect checking of placement on summit of the sphere was fixed. |
