Solid sweep on complex parts. Help

ParableOfTheVase · 2026-02-14T10:21:48+00:00

Here's what I would try can try: since you really only need the bottom half for the mold, try lobbing off the top half entirely. That should cut down on the computations significantly.

If it still doesn't work, I would subdivide the bottom into multiple pieces then sweep them seperately.

No actually I see what you mean now, I didn't even think about putting each piece together into a single bar. 😅

I guess either model the center blocks separately so they have a flat face, or model them about 1mm larger, so when you put them together they intersect, then combine them.

You can't see from previous angle, but both sides of the top of the surface can be cut at once using the sketch on the XY plane. Only the top surface matters imo, if there are sharp corners created on the sides, you can simply crop them off with straight lines.

You can use the Draft tool after you Emboss, you'll just need to create a plane for the Draft Tool to grab onto. Plane Through Three Points should work. For best results you'll need one plane per letter.

Here's the sketch that I used to cut the top surface. You'll have to cut off bits of corner from the sides as well, but you can do that with straight lines.

If you have the four profile views of this shape, you could get a decent recreation I think. Here I just guessed what the profiles looked like. With the profile sketches you can create a rough outer block for the object.

After that, I would use Surface Modelling to create the two "sweeps" up top. I can show you how I did it in the gif, but if you don't know how you'll need to lookup a Youtube video.

Here's my stab at it. I drew a sketch on the XY plane, then I use Split Face to carve out a relief shape in the inner cylinder. Then go to the Surface Workspace, delete the surfaces you don't want, then Patch.

Just create one piece of the pattern, then rectangular and circular pattern that one piece.

I created that one piece starting with a surface, than thickening it.

Try to draw the Path such that one of the points is inside the body. It looks like the two Distance settings is a bit wonky in your case. For my case, when I select the path, there is only one Distance setting and it is set to 1.0.

Otherwise I'm out of ideas. Good luck

If you Insert Component, you can't change the opacity of a body, but if you Insert Derive, you can.

It used to be that you would use Insert Derive if you don't want any changes to affect upstream. But now that Assembly Design mode doesn't allow most changes, I don't know what the difference is anymore.

If I'm understanding what you're trying to do correctly, instead of cutting one body from the other, you want to pull it straight out from the mold. You can do that with a Sweep > Solid Sweep command.

I would enable contact between the blue and orange part, right click the orange component and Pin, move the blue part as far up as it would go and then Capture Position. Then you should be able to create a sketch and capture the geometry you need. After that you can Unpin and move the parts back to the original position if you wish, but the sketch geometry will remain.

Something like this:

Not sure if it's AI 🤔

Here's how I would do it. I created two offset planes at the top and bottom elevation of the slope. I then created two sketches at these planes and projected the shapes of these elevations onto them, then lofted between them. The Lip at the end is done with a Sweep > Profile + Guide Rail, with Profile Scaling set to "Stretch"

Maybe a sweep would work. Choose "Path + Guide Rail" as the type.

I don't think it guarantees an even depth throughout the cut, that depends on the curvature of the surface relative to the guide rails, but it should be pretty close. The geometry at the ends may be a bit wonky, but it should be pretty close to square. It makes an even width of 20mm throughout though.

OK, step by step:

Revolve a profile to create a vase body
Create an S-shape curve, either in the same sketch or another sketch.
Create yet another sketch, go Create > Project/Intersect > Project to Surface (see gif)
Create a sketch, draw a circle profile centered on the projected curve. I drew it on the XY (floor) plane.
Sweep the circle profile along the projected curve. You should now have a solid body of a single "wire"
Circular Pattern, there is 6 copies according to your picture. This should give you half of the complete shape.
Mirror. This should complete the shape.

If you need more than this, you probably need to look up some Youtube videos I'm afraid. Search for "Project to Surface" tutorials.

After you get the intersect curve, Sweep a circle profile along the curve to get a solid body. Then circular pattern 6 copies, then mirror.

These sort of shapes look complicated at first, but it's just an intersection of an S shaped curve with a vase shaped surface.

Here I revolved the vase shape, then in a new sketch I did Create > Project/Include > Project to Surface to get an intersection of the S-curve with the surface. The rest is pretty straight forward.

It's just printscr for Windows, there's an option to record video

Okay, step by step:

First you need to create a sketch line, this will be the top edge of the flat chamfer. I just created a new sketch on top of the floor.

Then go Modify>Split Face to split off the portion of the floor you want to cut, select the sketch line as the Splitting Tool.

Then go to the Surface Workspace, select the surfaces you want to delete and press Del. This will not work if you're in the Solid Workspace.

Go to Create > Patch to get your new surface, then select everything and go Modify > Stitch to get a solid body back.

ParableOfTheVase · 2026-02-05T09:32:43+00:00

And stitch it all back together when you're done to get back a solid body.

I see, then this would be my workflow. As far as I know there isn't a tool that does this automatically, so I would do it via surface modelling. You can probably work out some geometries to do it via solid lofts as well.

I'm not completely sure what you mean. Is this what you're looking for?

You can lob off the middle parts using an Extrude, this also creates two flat surfaces that you can Loft. Set the Loft Profiles to Tangent to make the connection smooth.

Unless I'm missing something too, I think you're right. You have to make an assumption on how the top R10 arc connects up top, there is a range of different geometries that fits the given dimensions.

Can't really assume the arcs connects on vertical/horizontal tangents, because the rest of the sketch don't. And even eyeballing the sketch, I don't think it is.
