I am new to this program and I am trying to learn how to extrude three perpendicular cylinders along the three axes. I have followed the first tutorial and learned some of the basic operations.
I try sketching a circle on each of the three planes. Then I extrude each of the circles perpendicularly to each their plane. However, they do not appear to render as solids. They just result in a whole bunch of lines and points, effectively making up three intersecting wireframe cubes with circles at their corners.
I attach a screenshot of it in isometric view. I simply cannot figure out what is going on here. How should I do this? I am clearly doing it very wrong.
