Hi, I am new to shapr but I am trying to make this so that the cylinders are holes and then the rest of the body is solid however when I try to extrude the other face separately it just says extrusion failed. This is prob a very dumb question and I apologize if it is. Thank you for your help!

The extrusion failed because you have your cylinder surface tangent to the edge of the body you wish to extrude. Either enlarge the sketch you wish to extrude or move the cylinders away so they are not tangent or make the cylinder diameters a little smaller.

BTW, it’s easier to extrude the desired body without the need to start with cylinders and then have to subtract them.
