Is there something simialr to OrientOnCrv that just moves an object along a curve? I have an object already positioned on a curve and just want to move/slide it based on the curve’s normals.
I get lost a lot of times with OrientOnCrv, trying two or three different cplanes or even moving the object off the curve and positioning on the cplane to get it to work.
Hi Eric,
Would that functionality be described by :Sliding an object over a curve?
See if the attached script functions like you want.
SlideOnCurve.rvb(1.5 KB)
.
Note that it is a little hacky so escaping will leave you with the objects oriented somewhere on the Cplane.
An Undo will get you back where you started.
@Pascal I think such functionality would be good to have as a genuine Rhino Command:MoveAlongCrv
Drag and drop the script over Rhino; it will register the alias “SlideOnCurve” and it references the script file so you need to keep that script file in the folder you drag/dropped it from.

Hi Willem- you should take the call into the sub out, if I follow what you are doing, or comment it:
Call SlideOnCurve()
otherwise the script will try to run every time Rhino starts.
But. yeah, something like this would be nice, I’ll add it to the pile. Thanks.

@Pascal_G I was just hoping there was a command like this, it would be great to be able to move clipping planes along a curve easily, maybe using the gumball?
Speaking of clipping planes, it would be handy to be able to intersect the clipping plane with objects to get section outlines. Am I just doing it wrong?
Hi Pascal,
The problem was with another script, I accidentally mixed a few lines of your script with mine.
Where you add a startup script and create an alias for the sub,
I just create an alias that loads the script. This to prevent a large list of startup scripts.
However I have no idea what happens behind the scenes when multiple scripts are loaded that contain same-named subs and functions? I guess my thinking was that an alias for Loadscript would isolate all subs and functions in that script file, yet from other experiences I know that is probably not true.

Would this be different than what Section Tools does: SectionTools Plugin for Rhino [McNeel Wiki]
Rhino definitely should have movealongcrv as a default command. Have been wanting this more and more lately.
