 View Revisions: Issue #31835 Summary 0031835: Modeling Algorithms - step by step Boolean common produces bad shape on given three cylinders Revision 2020-10-12 03:53 by Vico Liang Description There are three cylinders with same size which are perpendicular with each other. 1. Load the given file three_cylinder.brep there are three cylinders: cylinder1, cylinder2, cylinder3. 2. do boolean common with any two shapes: common1 = cylinder1 x cylinder2 3. do bollean common between common1 and cylinder3. The final shape is bad from the result view. It maybe a modeling problem or meshing problem. Test environment is occt 7.5.0 beta. It works well in occt 7.4.0.
