I'm having difficulties with the sweep feature, can anyone help?

tyler_vandewal

I'm going through the Part Design tutorial creating a paperclip, and the sweep feature doesn't seem to be working. The figure I'm using to sweep is a 5 mm circle, and the path is a simple paperclip design that isn't an actual part yet, just some lines. The sweep path is on the top plane, while the profile sketch is on the right plane. At first it goes well.

However, after this, it just seems to break.

I tried selecting the whole figure anyways to try and have it fix itself, and it worked to an extent, but the size is all wrong and it's just off for some reason.

Can anyone help? I'm not sure what's going on here. I followed the directions, all the dimensions are correct and they're all on the correct planes. All arcs are tangent to all lines. I don't have a clue.

Can you post an ISO view of the interaction between the 2 sketches - the profile and the path - is the circle centered at the endpoint of the path?

In your first image, there is a warning - this indicates what @Jenny_Johnson is saying

@Jenny_Johnson
Yeah, the tutorial said to apply the coincident constraint to the center of the circle and the endpoint of the path sketch

It looks like the center point of your circle isn't quite on the end point of the line (the plane is slightly too far). For your path sketch, is that endpoint coincident with the right plane? It might be slightly to the left of where it should be. However, I can't tell 100% from the screenshot

Make it public and share the URL - would save a lot of effort and second guessing.

Ah, that's a good idea. Here it is https://cad.onshape.com/documents/5ae69fc455ac8762ac999cba/w/1ae31d2470f62e2ee0342a94/e/1b43d1d755a867e6b631172f

@alnis_smidchens is correct about the gap between your profile and your path:


If you make sure the profile sketch is touching the start of the path, everything will behave more nicely.  That is what the info message at the top of the page "For best results ensure that the path intersects each profile or its plane" is trying to tell you, as well.

Jake_Rosenfeld

You are probably missing a constraint on the path: 

If the sketch were fully constrained, it would be black instead of blue.  Maybe the start or end point of the path is supposed to be coincident with the origin?  I am not familiar with the lesson, but I could look if you posted a link.

Okay, thanks for bringing those to my attention, I'll see if it works out. Here's the link to the lesson:

The paperclip part is the second or third part of the lesson, though.
