Sorry my friend you can not do this in part. You have to use assembly feature of Inventor for this.
Actually there is way but i don't know will it work or not.
Provide more detail.
Hi, Thanks for your reply. I found out the way.
1) Created Plane by using option "Tangent to the surface and parallel to the plane"
2) Created "Point" by selecting plane and perpendicual - axis
3) Used 3d Sketch to draw line between two component
4) Created Frame using Frame Generator
5) Extended the Frame Created and Trimmed to the surface by using option available in the Frame
6) And finally used normal sketch & extrude option in assembly to remove protruding elements. and made my day go......
if u feel some other option to do this.....do ping me.........
