How do I create a ramp which is blendet into stairs, while I can adjust the incline of the ramp ?

Hi guys,

im really really really a newbie on Rhino an on GH, so i do not have many experience in both programms because i started to learn them 1 week ago.

So the thing I tried to create for my architecture studies this semester is a ramp, which is blendet into stairs. I tried it very hard manually and I even succeeded a little bit, but its all a mess and it took me so long to get this result, but even then I have no controll on how to change something without to redraw everything new. I have attached the file im working on in Rhino.

The thing is I need an incline of the ramp from 6% -10% max. to guarantee an disability access. I just want to know a way where i can adjust the incline of the ramp and the ramp is still blendet in the stairs while adjusting it. If that isnt possible i hope you can help me to figure out a way to just adjust the incline of the ramp when the top and/or the bottom ends are fixed.

I hope anyone knows what i mean an can help me.

Thanks a lot,

Greg Moody

It's always difficult to ensure that some shape adheres to a set of rules, that almost always requires some sort of iterative process which,

Validates the current state,
finds problem areas,
attempt to fix those areas,
repeat until no problem areas remain.

Grasshopper is not suited for such a process, though some plugins (most notably Kangaroo) are.

It would be fairly trivial to build a real-time analysis mode for your shape that will at least highlight where the slope is too steep or too shallow. The attached file will show too shallow parts in white, too steep parts in black, and a yellow->green->blue gradient between 6 and 10 degrees slope.

Hi David,

thank you for your fast reply. This script helps me a lot thanks!

The only drouble im now into is, that when i apply the points to my curve, the generated surface is going to spin into it self.Do you have any idea how i can fix that?
