i am very new to Grashopper and Rhino, and i think i do something wrong.
I have downlaoded and install all the programms and the files i need to create a (couple of) gyroid from the youtube tutorial.
everything works fine and i can change my gyroid how i want , thicknes etc…
when i save as step-file, every step file is empty. If i try to read the step-file with other programs , there is nothing, Inventor/eDrawings etc…
