Hi

I’m Practicing my little Knowledge in Dynamo trying to model a 3D Moebius Solid, when i thought i have finish it, i saw that the loft i apply to the geometries is open when its supposed to be a closed shape, i have tried several solutions but none of them works correctly, does any one know how to solve this?

Can you post a camera export of your Dynamo workspace?

Hi @rodolfo.francozamudi

Please show complete graph with all the values. If your graph doesn’t fit in the screenshot use camera export as @jacob.small mentioned above.
