Curve on surface

[wilmath]

I created two surfaces by copying the sketch of the first and then extruding it at 90 degrees and then trimming.


I wanted to create a curve that would run across the diagonal at the top so that I would be able to use VSS. I was able to create a datum plane at the diagonal and then use "create entity from edge" to get that trajectory.


but I was curious if it would be possible to use the curves command from the style tool. I tried it but could not get the points to follow that crease even when I was using the shift key to snap. It was like ordering a chicken dinner and then having to chase the bird around the restaurant!


The picture shows how far I got. I couldn't get the curve-on-surface to follow that crease across the top.

Sorry here is the picture

You can get the trajectory by copying if that works for you. Depending on your version the key selections may be different and you may need to set the selection filter to geometry. In WF3 you can select the first end of the curve, hold the SHIFT key and select the other end, then Copy, and Paste.

Thanks Kdem, that is an easy way to do it.


I am still interested in using the curve-on-surface command. Will that command work in this application? I felt like I was fighting the tool and obviously doing something wrong.

I went back and tried and yes you can. I assume you used the curve command in style. Instead of using that use the Create COS by intersecting surfaces command (see pic 1).
