Hey guys, I'm having difficulties extruding this sprocket. I'm not sure why its doing this can some help? I've been trying to figure this out for a while now...
Check your sketch, it's has open edges at these 2 places
Open the sketch and right click. Choose select chain and then click towards the top of the profile. You'll see it selects everything but a section on the bottom right. Zoom into the area where the selection stops and you will see that the endpoints are not coincident in two areas. As soon as you make the problem endpoints coincident, you should see the sketch turn blue. I am using 2018, but i believe the sketch shading color has been around since 2006. Either way, once you complete the broken profile, you should be able to extrude.
Thanks guys for pointing out the errors, I am now able to extrude the part successfully
For the future, instead of trying to do that all in one sketch you might model one section of it first, then finish with a circular pattern (7 instances in this case).
Yes, what Glenn said. In fact, I'd model half a section, mirror it, then make the circular pattern.
Add in I would start it on the Origin that would make it a lot easier to fully define your sketch.
I am aware of those methods, I just jumped the bridge and converted the 2D autocad drawing to solidworks entities which is why all I had to do was extrude the part..
