I'm developing an application that imports a STEP file, tessellates shapes in the STEP file, and exports an X3D file.
I'm using OCCT 7.5.0.
I've got the wrong tessellation for pipe-alike geometries as shown in the attached PNG file.
The STEP file shown in the picture can be downloaded from the link: https://grabcad.com/library/gtcp85-98d-1
I failed to directly upload the STEP file because it is too big (over 100 MB). I'm sorry for the inconvenience.
I tessellated each shape by using "BRepMesh_IncrementalMesh" while setting "isRelative" to "TRUE".
The angular deflection was set to the default value.
Is it a bug?
