Using the "Sweep" command over multiple line segments.

robert_melascaglia

Greetings All

I have created a multi-line segment to ultimately use to sweep a profile across it.  I created the sweep profile at one of the line segments and everything works just fine.

However, when sweeping the profile it creates "one part" although you can see the demarcation lines of the individual line segments.

Question:  How do I change the "one part" to the "multiple parts" that it really is (and should be)?  I realize I can create the "sweep profile" with its own "normal plane" at each line segment, then sweep, and have all the unique parts - but is there an easier way?

Thanks,
Robert

Why “should it be” multiple parts?

one sweep = one part

if you create a sweep along the first segment you can create the next sweep using the end face of the previous one and select “New” to create a new part. No extra sketches required.

Why “should it be” multiple parts?  Because I want to define "certain segments" in an assembly and not the entire "one part."

You have a few options. You could sweep the entire profile as one part and split the part at the desired segments. Or you can sweep an individual profile, use the face of the last sweep as the next profile and so on.  Feel free to post a link to your Document for us to take a look at.

Good Luck!

John, very interesting in lieu of creating the three-parts I desired with three sweep commands.  Splitting the "one part" into three - that is what I am after.

Below is a simple wrought iron top rail that I want to "split" into three parts - thanks you for the advise.

Thank you John - it worked beautifully, and with just one sweep command.  Something I will not forget.

I have a strange project I'm working on. It's a barrel cam that will eventually move a pen, and the radius is mapped to the y coordinate on paper. Anyways, I have a 3d spline for the sweep I want to make, but the sweep always makes some weird orientations of the original shape, and trying to sweep between two faces only prompts onshape to try and make multiple sweeps. I can't split a 3d spline.

Any Idea how to split the 3d spline or to fix the rotation of the sweeping face?

did you try playing with the 'orientation' dropdown?

If that doesn't work (yet), consider making a face to aid in directing the profile direction like in this marble track example i made for someone a while back that was struggling with someting similar.

this is from when routing curve was still in beta, and edit curve did not yet exist.
