Linies between two curves

I am sooo doomed... I have to model an array of lines which have a constant spacing between two curves. of course perpendicular....
Any idea how I can do that in MoI?

Hi Lemo : some easy :D
menu Transform / Array / Curve -( Flat,None...);)
Twice crossing! And enter your number or your measures for a regular interval!
A by B, then B by A ;) (or the inverse of course
Or just A by B depending of what you want :)

Hi Rainer,

Well, one problem is that what you are asking for there is actually impossible for the general case, since any 2 random curves do not necessarily even have any perpendicular in common between them.

For example here are 2 curves that have no shared perpendiculars between them:




The case where you do have perpendiculars at every point is when one curve is the offset of the other one, like this:




In a case like that, you can draw in one line and use Transform / Array / Curve to replicate the line at a constant distance along one curve (the distance along the other curve will vary where things bunch together when going around bends, but it will be all perpendicular), like this:




But maybe I don't understand what you are trying to do, could you maybe post the model file with the 2 curves in it that you are trying to work with? That would help to clarify it.

Yes, the further I got into it I understood more and more that I did not really know what I was asking for....
What I ended up doing is a projection of a grid onto a plane I made between the curves, then I (rhino..) made a median curve and moved the line segments to equal spacing with snapping. I'll make a photo of the job once it's done.... Crazy table legs....
Cheers
