Issue adding thickness to organic shape

Hi there,

For my project I am creating a cantilevered pavilion, which follows an organic design and shape. I have created the shape I am wanting for my building in Rhino, however when I attempt to add thickness it doesn’t display properly and the final product ends up have gaps.

I have tried multiple ways to add thickness and the only command which is currently working to an extent is OffSet surface. This is giving the thickness I want in some areas, but fails in others. I understand that the shape I have created is fairly irregular and complex which may be causing this issue but I wanted to reach out and see if there was an alternative way to add 20cm worth of thickness, so I have a “roof” and “walls” rather than a skeleton.

I have uploaded 2 screen shots demonstrating my issue, as well as the rhino file.

Thanks, Louisa

Shrinkwrap it :slight_smile:

This model is modeled in Meters but with only a .01 meter tolerance. I expect the detailed required here is smaller then that.

I would shift this to mm units to there is some tolerance to play with.

Also, the surfaces to twisted up, this will lead to a mess in the offset. Setting how the surfaces need to flow from one to the new would help in this case.

Cleaning all that up will get a much better chance of this working.

Adding cross sections and using 2 rail sweep will give Rhino more information to sweep those surfaces correctly:

Rhino 8 with surface offset will make a solid if the surfaces mark sense in the offset:

Hi Scott,

Thanks so much for your reply. I’m very new to rhino and this is my first time using the software for a project like this, how would I best approach setting how the surfaces need to flow from one to the other? I am also unsure what you mean by 2 rail sweep.

I also changed the file to mm, however it didn’t give me the option to scale the building up when I changed it, therefore it is now only 80mm long.

Thanks Louisa

Changing the Units under Tools pulldown > Options > units will give the option to keep the objects the same size.

Here are some pointers on 2 rail sweep:
