A cad software is only as good as the basic sketching is

...or am I missing out on something?
I cannot find that it's possible to snap along an edge, corner, midpoint or anything else on an extruded model when sketching on a face.
Also when you are transforming some line or anything on a sketch, snapping doesn't seems to work.

Hit construct before use to make them constrution geometry.
I agree with the title and that makes Onshape pretty awesome piece of software.

chris_8 OS Professional Posts: 102 PROI agree OS sketching lacks in usable "live" points from background sketches or other entities. You can make a point, then tell that point to be coincident with a corner from something in the background, then use that new point to start a line. But you can't simply compress all these tedious steps by starting a line at the corner of something in the background.

3dcad Member, OS Professional, Mentor Posts: 2,472 PROIt can be also good thing if you have a lot of background stuff.
I have often cases where new line begins 1mm from something in the back, I hate when cad tries to be smarter than me and snap onto things I don't want.
But we do have shift -function to disable snapping so we could also have button to wake up everything in background?//rami5 -

mahir Member, Developers Posts: 1,301 ✭✭✭✭✭I've always seen the benefit of both camps (auto vs manual inferencing). I actually like the OS method the best. It's a nice compromise between the two.5

emmett_weeks Onshape Employees Posts: 29For the purposes of stable model regeneration, it's best to avoid projecting model edges into a sketch. The reason is that we don't allow projected edges to change geometry types, so if an edge that projects into a circle becomes tilted with respect to the sketch, the projection will break since it is now projecting as an ellipse. Adding a constraint directly to the model edge is better since it is more likely to continue to work when the model is changed.8

I'm using Firefox and Safari.
Creo way sounds interesting. I am used to SW where snapping is easy.
I hope people aren't projecting a lot of edges just for trimming in a sketch!!! One thing I like about Onshape, is that it will automatically trim the sketch with the part during the feature creation:
