thanks, looks pretty good. yes, I would like to rotate the profile based on the curvature of a second curve at a point which corresponds to the divison point on the first curve (where the profile gets placed)
can you you attach the definition file ? thanks, Peter On Oct 18, 1:52 am, visose <[EMAIL PROTECTED]> wrote: > Sorry, the explanation is not exactly right since the copy and > orientation happen at the same time and in the same component. > New explanation: > First divide rail curve in the number of desired points. > Then calculate tangent direction in the "rotation curve" at the same > parameter of the rail curve. > Then place profile curve in the rail curve a number of times using the > previously acquired points and at the same time make them face the > previously acquired direction. > > On Oct 18, 2:35 am, visose <[EMAIL PROTECTED]> wrote: > > > I tried to replicate what I think you are trying to > > achieve:http://grasshopper3d.googlegroups.com/web/arrayrotate.jpg.
