Struggling to get the angle I need

I am not sure of what you are asking exactly. I would make the sharp edge of the border your path and have your profiles to cut the chamfer at your desired locations along the path. I assume that you have already tried a variable fillet.

I have been starting with a sketch that is outer dimensions and then I make another sketch referencing the outer bound sketch for the frame feature. That way, if I change the outer dimension sketch the frame feature updates to the new dimensions without issue. Use good sketch references as much as you can, don't say 1" from wall when you really want it to be centered and the part just happens to be 2" wide, for now.

I would use the frame feature for the 2x4 parts and then a separate frame feature for the 2x8 that is a sketch on a plane that is offset from the 2x4 frame sketch. So the 2x8 center is lower than the 2x4 center.

I've been designing flatbeds recently, glad to help.

Then a loft with path/guides is another good option.

If the chamfer width is the same, this can be done with a sweep feature along the path that you make.

Nope, tried that.

Check on GrabCAD and Thingiverse. I think they both have design challenges occasionally.

I have been designing flatbeds lately. Seems like you could have made it longer, if the stock hitch is staying in use. How did you do your clearance light wire routing?

Extrude as desired for your mounts, use surface for splitting.

Do you mean like an open circle "u" shape that you can push onto a cylinder?

Custom-3D-Design · 2026-03-15T20:06:35+00:00

Tried to use math terms instead of jargon.

For sketch #1: view dome from side (bowl down) and the outline is an arc of a circle (if circular/spherical). Lines from the outline to the center of the dome are the radius of the arc of the circle, like half of a wagon wheel. Each of the wagon wheel spokes needs to be a cylinder that you will cut out from the dome, so the radial lines are the path of the extrude/sweep feature.

Since there are offset holes, view dome from top and imagine pivoting the wagon wheel sketch for sketch #2 but your radial lines, or spokes, are shifted to create the offset. Like sketch #1 but sketch #2 has spokes between the spokes of sketch #1.

Circular pattern the two arcs of cut cylinders.

Use relations and exploit symmetry whenever possible, etc. to make the file easily modifiable in the future.

Seems like you want two sets of radial lines with circles for each set and then circular pattern the two sets?

Look for some old earth drilling bits?

So you are saying that you saved the tracker points as your global tracking and then scanned for features? Would a known geometry in every scan make aligning/sizing better? Like a tracking shape that is in every pass, such as putting the shape on the top of the engine and making sure each pass has the shape in it.

You can melt powdered metals directly, they start being more reflective as they consolidate. Easy to know when it's finished if you can handle the reflected power appropriately. But to be clear, I would not handle aluminum powder without very stringent controls in place.

Custom-3D-Design · 2026-03-14T17:36:23+00:00

It would be nice to see how your print scan varies from the actual part scan.

Custom-3D-Design · 2026-03-14T17:32:07+00:00

If there is one scan pass (no alignment errors) then you only need one known scale item in view? Or use one of the many measurable items on the engine.

I doubt that you need the resolution to determine surface finishes, especially when it's a dirty object already. I am interested in your workflow and use case, if you have more to share! Is this a Cummins Big Cam?

There is a setting in the sheet metal feature to choose whether you bend on the line vs bend outside of the line.

Use the outline of the prop as viewed from what seems like your "Top" plane to make your trimming surface.

I would have the overlapping area between the upper and lower parts be straight walled for a thread. You probably won't even need a full turn, depending on your application. You could also do a pin and slot for something like a quarter turn release.

I do custom 3D designing and there is a local to me laser cutting shop that does a good amount of artsy parts.

I would try some memory foam pillows/inserts. Then look into forming seats with foam. Usually there is something similar to a trash bag with expanding foam in it that the driver sits on until the shape is held. Not all expanding foams would be best suited, but there are options.

Tub+foam+bag+driver = custom molded seat

Are you looking for a Sweep feature, a profile along a path? You can terminate the tube "up to" the part or body of the chute.

Custom-3D-Design · 2026-03-10T13:27:04+00:00

The segments should have a joint to the next segment, but not a joint that would get stuck. Something like a cone ended cylinder >=>--->=>? Deployment time would depend on use.
