trying to do a sweep. what am i doing wrong?
i created a profile to sweep as well as a path but all i get is a red shape that will not work. no idea why.
I made a simple project file to illustrate the problem.
first i tried using the path that is the basis of the pocket. that didn't work so I created a redundant path to sweep along. also did not work.
what am i thinking? why is what i am thinking wrong?
edit: ok, i'm using sweep wrongly, i should be using 'revolve' but i didn't know it existed until now
Re: trying to do a sweep. what am i doing wrong?
You used the subtractive pipe instead of the yellow additive.
It is recommended to use the simplest tool possible. Which in this case would be a revolve, not a sweep (Pad is simpler than Revolve is simpler than Sweep and Loft).
It looks to me as if this feature should rather belong to the first body?

Re: trying to do a sweep. what am i doing wrong?
your initial idea is good, like chrisb said you have to addpipe
rotating will pose the problem of the center of rotation which is not Y

Re: trying to do a sweep. what am i doing wrong?
thanks
got it with rotate, but will try pipe later.
here's the freecad file i've been pecking at for several days now: i was able to make one raised circle of 2 that i need because it was at a 90 degree axis. but i have another donut to draw that is on an angled face. best practice to draw a 3d feature on to an angled face? I will search in the meantime. i want the angled face to become a plane that i can use in my geometry to draw at a 90 degree z axis to the plane of that flat face. I can draw on it at a bird's eye view but i don't know how to get a side view of that in order to draw a profile that i can subsequently rotate or pipe. I struggled quite a bit to make a sketch that is kind of in the right place, but i closed the green constrained sketch and now it's missing. any idea why that might be? (in the attached file, it says "profile to rotate but it's missing) and even if i do get the round thing made, i have no idea how to get it to align so it sits precisely over the hole in that part, which is why i would like to treat the angled face as if it is a plane that i can use as a reference.
also, with regard to the terribly intimidating tree view, the only way i can work with FC right now is if i ignore the tree view as much as possible, and work by clicking on the graphics instead and hoping the operations work and that freecad will automatically put the tree view together. Anything else and I break the model and have to start over.

My best Yoda: "Tree view your friend is."
If it distracts you, you should ask more about it because it is essential to understanding what is going on I your model.
Please discuss what you find confusing so we can help.

Re: trying to do a sweep. what am i doing wrong?
Right now I'm looking for a way to build perpendicularly from a face in a model that is at an angle. The only thing I can think of is to rotate the model so that the face is coplanar to the original xy plane and then working on it. also in my previous post, I made a green sketch and when I closed the sketcher, the green sketch i made apparently disappeared and I was wondering what that means.
Re: trying to do a sweep. what am i doing wrong?
Hmm...the way to do that at this point is with techniques discussed here: https://wiki.freecadweb.org/Basic_Attachment_Tutorial
In general you create the sketch on a base plane and adjust it's attachment to the desired position.
You can also select the face you wish to work on and create a sketch. The sketch will automatically be attached perpendicularly to the face.
But, at this time, this is not a recommended workflow because of a modelling issue called Topological Naming Problem.
See these for more details:

Advice for creating stable models
It probably means you used construction lines (blue) in the sketch. They are invisible outside the Sketcher.also in my previous post, I made a green sketch and when I closed the sketcher, the green sketch i made apparently disappeared and I was wondering what that means.

Re: trying to do a sweep. what am i doing wrong?
the problem with just selecting a face and working on it is that i can make a sketch that i can turn into a pad, but i don't know how to put something perpendicular from that face.
i could make a pad and then chamfer it to look like the simple profile i made, but i will look into those links to see what they say, thanks.
and the sketch i made showed up after reopening my project, it must have been some kind of rendering issue.
thanks for the tips, tips are great.

With a master sketch.
