Cannot Create Surface from Planar Closed Curve

Hello all. I hope someone is able to help me. I’m trying to create a surface from this closed curve in Rhino 7 and it will not do it. The curve is closed and is also planar (checked with SelPlanarCrv) and I don’t understand why it will not fill the shape. I often encounter this type of issue with hatching as well. Have attached file here.

Hello. I used the Patch command to create a surface. it seems to work better when scaling the model up. Could it have somthing to do with the template being used her?

Hi Magnus, thank you. I think you’re right and it’s the template and tolerances! I changed this and this has been fixed.

Glad it was resolved, happy to help.

Hi Monica -

Yes, for modeling something this small in a meters template, you’d better set the absolute tolerance to 0.0001. The alternative would be to use a default template in centimeter or millimeter.
