Creating Solid/Surface From 2 Circles

Hi, I’m new at Dynamo and got a question.

I am having a problem about creating a solid/surface from 2 different radius circles. Is there any way to do it? I tried to list.create and making solid but it doesn’t worked. I will be glad if you help.

Have a healthy day.!


To make a circle into a surface use Curve.Patch
To make a solid use Solid.ByLoft

Thanks. I used same thing but I guess I am having this trouble because there are many circles. I expected that using line as a guide will solve the problem but it didn’t.

So it giving the error of Unable to loft! : BAD_UV_SKIN_DIR – Surface U and V derivatives are in the same or opposite direction.

Thank you @Marcel_Rijsmus :slight_smile:

I you can attach a picture of the script, there are lots of people here that would want to dive in and help you.

So, here is the complete script and dyn file.

Dont mind the bottom warning, i was trying to find a way to do it. @Marcel_Rijsmus thanks again.

Edit: I removed other circles. So, just 1 pair of it left. It still giving the Warning: Solid.ByLoft operation failed. Unable to set the sections or the centerline! : TOO_FEW_COEDGE_LISTS – Too few distinct profiles where supplied error.

Edit2: I’m really getting confused. I took out “sequence” command. and solid.byloft worked for 1 pair of circles.

Try to rearrange your lists
now you have this

Make it into 2 (corresponding per solid) circles in a list, and 1 line per list (the line that connects both circles).

Hi @canberkkavuncuoglu

Transpose your circles lists along with Flatten to create loft:

thanks @Kulkul and @Marcel_Rijsmus. It worked great. Since I’m a newbie, i didn’t heard of transpose node. Thank you!!
