algorithmic modeling for Rhino
My first post here.
I made a simple open-curve in rhino and made copies in Gh... moved it in z, scaled it.
Probably it's because of the different path input from "Scale" component.
You can fix this by checking "Principal" option from the I/O Modifiers of input "G".(right click on the "G"(Geometry)input of Scale component's context menu and choose "Principal")
It would be easy to explain if you post your definition with internalised your referenced curve or along with your rhino file.
I would say your problem is likely a data structure issue. The control point (CP) function modifies the branch indices as you can see in the param viewer in the top right corner of the image. The loft will only loft data items which are in the same list, so in order to ensure that all items are being fed into the loft in the correct order and the correct branch, we flatten each input in a merge.
As you can see, the second loft gives you the desired output.
