I'm a clueless newbie here. I'm kind of stuck. I'm trying to reverse engineer this part and stuck on how to model the flat. Do you guys have any ideas? Any help would be much appreciated.
Sketch on a plane at center of cylinder.
Extrude cut.
Just use a extruded cut on one of the construction planes and cut in both directions so it goes through both sides, if the other cut is the same just mirror it. If this cut needs to be at an angle to around the pin create a new plane at an angle to one of the standard planes.
Speaking of planes. The planes present in a part model exist and don't change no matter what you do to the part in the future. So using those planes for mates in an assembly makes for a much more robust assembly. I use this a lot when I model a part by eyeball before I have the real part. When I get one I can adjust the model and the assembly doesn't fall apart as a result of the changes. If it does though it will always be one surface that I had to use.
Hope this helps
Create a plane that bi-sects the cylinder and like the others above me has stated, create your sketch. You can do an extrude cut through the part
Alternatively you can sketch the area on top of the cylinder and extrude it to surface to get the geometry you want.
Since you are new to SW, I'll give you a couple of pointers. Whenever possible take advantage of symmetry. Also, it is better to use the primary geometry (origin, top, front, right planes) to make your features, if possible (for instance, I'd put Rubén Rodolfo Balderrama's extrude cut on a primary plane). Then always add your fillets and holes last.
Following those simple rules reduces parent/child relationships and makes it easier to make changes later.
Thank you everyone! With your help I think I figured it out.
