Arraycrv roadlike problem

I am having some difficulties with the array along curve command and i am hoping someone will be able to help me out.

I am trying to array object along curve and i want to have consistent up direction, but i somehow don’t see the results i am expecting.

I use arraycrv command, type roadlike and this is what i get:

this is not right, is it?

i can only get it to work whe i use vertical helix:

the command definition states:
Objects follow the curve but maintain a consistent up-direction relative to the construction plane.

so? any ideas?

Hi Jakub- here’s a script to do that for now- it is, I think, on the pile for V6, no promises or anything…

To use the script, extract and save the .rvb file from the attached zip archive, then drag and drop the saved rvb over an open Rhino V4 or v5 window. This will load the script, set it up to load on startup in the future and register the alias


that will run the script much like a regular command. An alias can be typed or added to a toolbar button or keyboard shortcut (F-key).
