sewing extruded solid with a swept edge

[ilovedividends]

I attached a prt file. This is a simple exercise that I don't understand.

I have an extruded semi-circle to which I added a nice bridge curve contour by a sweep function. At this point I unsew one face of the solid, then sew it all back up but there is always a surface in the middle of the part.

Thanks.

The Unsew turns the solid into a sheet body. The surface in the middle is the surface you unsewed from the solid to make it a sheet.
What's the issue with having that sheet?

Thanks for the reply.

The sheet that was created from the unswew is relaxing with it's feet up inside the body...see the attached file. How do I get it to take a hike so the inside of the part is clean if I were to do some subtractive modeling?

Use 'Delete Body' on it.

however I would try and avoid creating the sweep in the first place, see attached for one way of doing something like the end result.

Thanks, I like that approach. I may need to sweep the bridge curves b/c the part has contour. see attached.

It appears just deleting the body worked nicely.

To me this is a very backward way of working, ( on the other hand i have never understood the use of the unsew feature...)
If you wish to copy a face for other purposes, the command name is "Extract Geometry".
Why don't you include the vertical edge of the extrude such that you have a closed section to sweep, (+ Preserve Shape to keep the logical face division.)
See attached.

- Bridge Curve4 is suppressed since it's not used. delete ?

The semi-circle I am dealing with is contoured so I was under the impression that I needed to use both guides and therefor the sweep had to be a sheet not a solid.

There's still no reason why you couldn't have created your 'sweep' as a Solid to start with and then simply Unite it with the central 'core' part of the model, as I've done in the attached modified version of your model.

yes, thanks, I was only selecting the bridge curve and not the edge of body, therefor, I was only getting sheets from the sweep. Originally I was doing this with all sheets and no bodies so I completely missed that detail. thank you.
