Grasshopper

algorithmic modeling for Rhino

Hey there,

Could any one help me solve this issue...please see attached images, and if your feeling really helpful I've attached the files too!

So I have a site model and I want to contour the layers to laser cut.


Can anyone identify where I'm gong wrong and why I'm not getting the correct results?

When I put the model through grasshopper it doesn't cut the site, sometimes it cuts the voids...I think the photos should explain the issue better...

Thanks! A

OK so the Rhino file is 14mb! So I've uploaded it on dropbox...https://www.dropbox.com/s/7vm7qi15jk0bszi/Contour%20model.3dm?dl=0

And here's the grasshopper one... Thank you

Hi Anna, your brep has 831 naked edges, which is the why the contours will not be closed curves (to make the planar surfaces from). You need to fix the edges first, then try this:

Notice: you can also use "save small", that will eliminate the render meshes from your file (which will be recomputed when you open the file)

Hi Luca Anna,

You are on the right track.

The problem is not your definition, but the geometry inside rhino.

Try to remodel this to get a valid closed polysurface and you will be fine.

Best,

Phillip
