Beginner help – Simple parametric tower (Grasshopper, Rhino 8)

Hi everyone,

I am an architecture student and a beginner in Grasshopper.
I’m using Rhino 8.

For a university project, I need to create a very simple parametric high-rise building (tower) in Grasshopper.

The requirements are:

  • Base curve set from Rhino
  • Parametric number of floors (slider)
  • Parametric floor height (slider)
  • Simple straight vertical tower (no twist needed)
  • Loft or extrude solution is perfectly fine
  • No need to bake geometry

The goal is only to clearly demonstrate parametric control, not a complex design.

I’ve just started and my Grasshopper canvas is still empty (see screenshot).
Any advice, example definition, or basic setup would be greatly appreciated.

Thank you very much for your help.

Best regards,
Endi

Generally, you won’t get help here without a demonstration that you’ve attempted something yourself first. If that is too daunting, try creating the tower in Rhino first, or writing down the steps you imagine yourself taking in creating the tower.

Hello
I think you can begin by looking at the examples

And like advised by Volker, you must understand how making something in Rhino first and understanding that all the decision you take with the mouse or the keyboard are most of the time a parameter in Grasshopper.
When you draw a line you begin at a point then go at a certain distance in a direction => 3 parameters (start, length, direction) …
