How to get trail/trace/line between a workingplane and a body that cut eachother

[a.wassum]

Hey togehter,

I have a curved body (exteriorplate) that cuts a working plane. I want the trail/trace/line where these to things cut eachother. Im new at Inventor but already used Catia V5 for a longer time.

Im thankfull for every advise ,

Greetings Alex

Start a new 3D Sketch.

Invoke the include intersection.

Attach your assembly (or a simplified dummy assembly) if you can’t figure it out.

Or start a new 2D sketch on your workplane and use "project cut edges"?

Depending on what exactly you have, if you start a 3D sketch and choose "Intersection Curve". You should be able to choose the surface and the plane > OK. Now you should have a curve that is the intersection of the 2 entities.

Thanks to all of you, appreciate it a lot. At the end I managed to do it with blandb´s solution. The problem was that I tried to do it in an assembly, so I created a simplified part out of my two parts that cut eachother.

Can you post a simplified example? Maybe there is another alternative for what you are trying to do. My approach was just based on a part, but if you are trying to find a common intersection of 2 parts for example, then there is another way.

Hi! I guess you would like to find the intersection between multiple parts. You can still do it within a part.

Open the assembly and edit a part in place. Go to Modify section -> expand the panel -> Copy Objects -> pick the geometry from another part -> set output = Surface -> check "Associative." Then the geometry will be linked to the edit target part. Then you can create 3D Intersection Curve within the editing part.

Many thanks!

Hi, thanks for your Idea. I wanted to find the intersection between a part and a workingplane, so at that point I couldnt manage to do it with your Idea. But I think the tool you mentioned might be usefull at other problems, thanks!

I have an assembly with assemblies in it. So used one of these assemblies (a frame with tubes) and I made a workingplane based on this frame. Afterwards I wanted to get the intersection between this workingplane and another assembly (a exteriorcover of a car). I managed to get the intersection/trail/trace/line with a 3d-Sketch when I combined the frame and the cover to one part. For me the best solution is an intersection between these to assemblies straight in the whole assembly.
