I know this has been posted before but I am still unable to get my model to extrude. I have attached my model. Hoping someone can point me in the right direction to fix my model so that I can finally get this extrusion done. I am doing a 3D topography of a person's property. The model consists of several stacked plates with tree geometry extruded into the surface. The model attached is one of the plates with the tree engraving geometry included. All 9 other plates in the work piece have worked flawlessly. On this plate all but the large left grouping of trees extruded as expected. The geometry for the extrudes was created in Adobe Illustrator and exported as dxf and imported into Fusion 360.
