how do you sweep one curve to another? Like a square to a circle that is above it along a curve. Every time I try I can only input one curve into the 'S' input. The same problem happens for lofting. There must be a something really simple I am missing. Thanks.
if you hold shift you can input multiple objects. The inputs are singular as they are a group activity. If it where say 2 inputs or any definite number it would limit the functions to that number of items. Also you can have a list of many curves and just input that and generally GH built in data manager does the job from there.
