Intersection between mesh and CAD surface

[[Er...]]

Hello everyone,

I need to produce a section that can be exported in IGS by intersecting a mesh with a CAD section which is neither a plane, nor a cylinder or cone. 

This seems to be impossible for a reason that I don't really understand. Does anyone have some intel on this problem?

I tried sections, curve and mesh editing options without any success in my quest. 

Thank you for reading me.

I have a problem with understanding what you want to achieve.

There is an option to intersect a mesh with a curve as i remember, but i was looking for something another and this wasn't working for me.
If you can try to explain it more deeply with a reason what for would be that IGES.

Thanks

Hi, 

there is no dedicated function for this. 

There is one iterative approach using a projected curve Construct Projected Curve:

• create curve on CAD
• project curve on mesh (shortest distance)
• project this curve back to CAD (shortest distance)
• project curve on mesh (shortest distance)
• ...

It is also possible to create a surface comparison/surface distance between CAD and this mesh area. Then use a defect element to filter point with positive deviation (points above CAD) ZEISS Quality Tech Guide

 wrote, intersection points between curve and mesh can be created directly. Many Curves or Section on the CAD perpendicular to the mesh/CAD intersection could be used to create intersection points, then use these points for a curve.
