I need to use this in an assembly so I'm going to need coincident and cocentric mates between the loop and a hole in another part, but it's not a face so i can't use a coincident or cocentric mate with it. How do I make that loop (sweep 2) be able to handle the mates I want?
I made the perimeter circle, but it won't appear unless I'm in edit sketch mode. So I can't use it as a mate reference.
Expand the feature and make its sketch visible. Then go to View -> Hide/Show and make the sketch visible. Then you can pick anything in the sketch to use for mates.

Simply turn on the visibility and you can see the sketch anywhere anytime.
But I recommend that you first ask questions about how to model the geometry correctly before moving on to Assemblies.
I would avoid using 3D sketches for planar 2D sketches.
You have modeled something that will be very difficult to model and very expensive to manufacture.
I assume this is a school project, but why not make it as if it was real?
In general (not this specific case) think about axis. Turn on temporary axis and mate them. Also think about the planes in your parts. Depending on how you constructed this, you may be able to use a plane.
Christian gave you the best advice, and you can also add a point that you can mate to.
What makes it expensive to manufacture? The way I modeled it or that's just how it is?
I fixed that part. I needed to make the loop bigger and it's also not overlapping anymore.
Much better. The end not being perpendicular to the shaft will require a special cut and orientating the cut will be challenging unless you are making this part on a 4-slide, then, never mind.
I'm just wondering why you need a loop for compression spirng? doesn't seem to have correct function???
This is the entire assembly. It's a bottle opener. The spring is a corkscrew. The loop is to attach it to the handle.
That's some looooong-ass skinny teeth on them gears. And a really fine thread with skinny wire on that corkscrew.
I must say, overall, Very Nice Job!
Thanks. That's how it told me to make the gears and corkscrew in the blueprints I got.
I would love it if you take a picture of that bluepint and post it.
There is much I can learn.
Not in this case. No one will profit (except in knowledge) from the posting and the posting is for educational purposes only. That makes it Okay.
This has been confirmed by the firm of Dewy, Cheatum & Howe.
No offense meant here at all Eric but those gear teeth are just gonna bend or break the first time you ever try using that thing!
Yes, I'm aware that it was probably only a modelling exercise but surely they could have given you something slightly more accurate than that?
But, if that's what you was given to do, then well done!
Dave.
Dave,
I think it'd be ok - similar as the one I have - see below image - one arm was pop out and now I use it for beer opener
Sorry Christian I still disagree, there's a big difference between his gears (teeth) and yours. His are narrow (weaker) at base and thicker at the top, whereas your version are thicker at the base (as they should be).
Dave.
Ok .. I think you're right - The tooth looks skinny - not sure how thick it is - hope it wouldn't be bent the very first time
Erik,
I would look at manufacturing the gear part, as well as the corkscrew itself from Adamantium or Vibranium. Anything less may bend.
Christian, did you type this is the wrong thread? Where is a compression spring mentioned? Who were you replying to?
One thing to keep in mind when you design is how to make it and make it cheap
Many things look nice but it can't or is super hard to make
the guys on the floors might laugh at you when they see the design
Eric,
the spring body is ok, but it will need a secondary operation to make the leg with a loop at the end as shown on your model - this would be done but it's hard so it's expensive
...if you turn on the axis visablity you can use the center axis... or, pick the center and add a plane normal to your axis..add a circle sketch and extrude a surface ...or,.. revolve ball to apply tangency..? (geez... look at all the responses!!!!)
