I’m pretty new to this software, so apologies if the answer to this is obvious. I sent off a file to a 3D printer, and they said my model was unprintable due to “cracks” in the surface. I see fine lines created where surfaces intersect the back of my object - I’m not sure what else they could be referring to. Could someone tell me if this would prevent printing, and if there is any way to fix this?
