It seems to me that before, if one displaced a surface and then used the sketch on surface tool, the curve would follow the ‘displaced’ surface and not the original non-displaced surface. It’s not doing that now and I could swear I did it before and don’t think I’m doing anything differently. Does/did this work or am I being delusional?
TIA
I guess displacement is render-only. I really thought it effected the surface…feature request for V6.
Maybe last time you used the HeightField command, and not the displace?
Not unless HeightFeild allows the use of procedurals.
Good point, and I have to say I didn’t check the name of the poster here Paul 
Maybe you extracted the displaced mesh and used sketch on mesh?
