hey mitch… thanks! that works great… (i like that i can just pick which end of the curve to measure from as opposed to using _Divide where sometimes the curve is drawn in the direction i need and other times requires me to reverse the arrows).
anyway, if it’s not too much trouble, the ability to pick surface edges would be great as that’s generally the type of situation i need this for.
I think this would be a good feature to include in the One Shot Persistent On Crv Onsnap. To be able to specify either a parameter t or a (normalized) Length value would be great. You get prompted for location and as it’s constrained to the curve a typed value leaves no ambiguity.
The attached script from my library is in vb (so no Mac compatible version right now), it offsets a series of points along a curve from a start point at a user-entered value for each offset. You can stop after placing just one point, so it does more or less what you want. It doesn’t work on surface edges.
I might be able to add a “From first point” option to the python script posted above, I’ll look into it.
from point is obviously a good one… another one i personally would use is divide between points…
i’ll upload an example a little later of a section from my last project in which i need to divide surfaces up according to my material dimension prior to splitting/smashing…
it’s all possible to do currently in rhino but yeah, there’s a lot of dup_ing/splitting/subCrv_ing/copying/pasting/undoing etc… it would be nice if there was a specific command (i.e.- not sure if i should all be tied into _Divide?) which has multiple ways to measure along a curve… the one in the original post was ,to me, the one which was most obviously missing but yeah, there are operations i have to do further down the line after placing that first point and it would be nice to be able to continue placing points/laying out a surface without needing to start cutting up the surface and/or edges.
