I started learning Rhino and Grasshopper a week ago so I am still a total newbie.
The reason I am posting this is because I find it hard to grasp how Rhino and Grasshopper
communicate and since I have a history with 3ds max I naturally tend to look for ways to emulate
familiar workflows in Rhino and GH.
I could not find simple and I mean really simple tutorials on Grasshopper which would help me with my problem hence I hope you guys will help me.
I drew a little diagram for better understanding.
What I am trying to do is to generate sweep profiles from curves (rectangles /w fillets) which I can then manipulate any time to try out different iterations
once they are incorporated in 5 different sweep 1 rail functions.
I set up a “sweep profile” at position 0,0,0 in 3d space and would like make an instance of it and move and rotate that instance of that sweep
profile to/at another position in 3d space (at the beginning of a rail curve).
There is however no “block” function in Grasshopper and I can not select the curve primitive rectangle in the Rhino viewport to “block”/instance it.
Ok, and when I draw the rectangle in the Rhino viewport and define it as such in GH I am not able to procedurally define width and height… :-/
Please, what am I doing wrong? How would you go about it?
This is my GH so far:
