Cylinders/Drillings/Taps Generated in Half Cylinders - Catia v5

3D Design

Hello 

When I create a cylinder, a hole with the pocket or hole option or a thread under catia v5 the shape generated is composed of two half-cylinders (see photo) separated by a line. I would like to be able to use these functions and generate smooth cylinders, because when I export to IGS these half-cylinder shapes create problems for the CAM that follows (it does not recognize the holes /holes). I dug into the options but couldn't find anything that solves my problem at this point. 

Thank you in advance.

Hello

No, no options, that's how it is with CATIA.

For exchanges with other software, the STEP format is more recommended than IGS.

Also look at the IGS settings if you export (surface representation mode) the result gives unconnected surfaces I have better results with (Volume-Shell)

Another idea, if you have other software than CATIA, some reinterpret the two half-cylinders  (this is the case for SW and Spaceclaim).
