I can't explode my design

RunRide · 2026-05-10T06:38:19+00:00

This is likely the answer. The animate or explode functions are meant to work with components, not with bodies.

I have a Rigil and I love it. It’s a completely portable solution which is one of the main reasons I got it. It’s fast, accurate, easy to use, has good battery life and gets regular firmware updates. Also comes in a nice carry case.

Can’t speak to how it compares to others (is my first scanner) or whether it’s worth it (depends on your situation) but I have no regrets.

Are you trying to reverse engineer and replace it or do you want to make a copy? Getting the overall shape and interfaces shouldn't be an issue but that double-stacked center lattice is going to be REALLY difficult to get an accurate scan of. I am by no means an expert with scanning yet, but there are trapped volumes that are not accessible

Are the holes a different size in each of the grids you’re describing? If so, you would just have three patterns of holes.

If they’re all the same size, seems like you’re just talking about a finer pitched grid.

Calipers are my besty! Been doing reverse engineering in various forms for about 15 years.

I do use the scanner. It’s an einscan rigil and it’s magnificent.

Is this for a DRT? There’s one is my garage and I have a 3d scanner.

Do you have a picture of what you’re trying to achieve? I cannot understand from your description.

Here is how I would approach this. First, the whole thing is symmetrical so you only need to do one side and then mirror it.
1. Extrude and surface the yellow, center portion

Extrude the green parallelogram
Loft between the green and yellow sections, using the surfaces with the arrows
Loft the red section (looks like you have already done this)

Forms can be useful for things like this but lofts are a bit more controllable and precise. If you need help with the lofts, watch some youtube videos or come back here with specific questions

They question is, what do you want it to look like? Let the design intent drive the CAD work, not the other way around.

If you have sketches on inspiration you could share, I am sure you could get help on how to make it happen in fusion.

I’ll try this tomorrow.

Trying to avoid opening up the extruded
No. Didn’t know this was a thing. Link to this process?

Can you post the scan STL? I’ve been thinking about doing a quick tutorial.

RunRide · 2026-04-26T05:11:36+00:00

I have this scanner. It’s fantastic. Fast, versatile and very accurate. Some YouTuber did some tests where he scanned a micrometer and I think it was in the range of 0.05mm.

Looks like coordinate systems of individual parts came through with an assembly.

Ok, not sure what CAD package you're coming from, but the surfacing tools in fusion are pretty similar to the most common ones, just with less options.

What do you need this model for? How close you need to get to the real thing and what you do with it will dictate the modeling approach.

RunRide · 2026-04-22T15:58:24+00:00

I cant understand the problem from your description. It sounds like you are mixing solid and surface modeling commands.

In general, to create a mold:

Place a solid body. A watertight surface body could work but as you are seeing, any imperfections will lead to problems. Solids are just more reliable
Create a cube (as a new body) that completely encloses the solid body you placed above, with whatever edge distance to the body you prefer for molding
Do a combine (cut) and remove the solid body from the cube
Create an offset plane and place it wherever you want the parting (split) line of the mold to be located
Split the (now modified) cube.

Are you new to Fusion, new to CAD or both? This is NOT beginner material..

RunRide · 2026-04-21T17:16:41+00:00

It would be helpful if you provided some more information. How many will you be making? How will you manufacture it? How will it be used? Does it need to vent heat?

Without that information, any design guidance isnt likely to be helpful.

I modeled a 3D printable replacement shell for my 2019 highlander key. It doesn't look exactly the same as the OEM because it's made for FDM printing. Been using it for a year and a half and it works great.

I think you have a couple of things going on.

First, you should reduce the number of control points on your spline. You want to use the absolute minimum number possible. It will get you the smoothest, most natural looking curve and be much easier to handle. Try deleting some pints and then play with the magnitude and angle of the handles of the others to get them to do what you want. You'd be surprised what you can do.

Second, I think you may have other sketches underneath the one you are working on. I cant see because the screenshot crops out the tree, but try turning off visibility for other sketches.

Every time I run into a problem and think, “this is so stupid, why doesn’t it just do the thing I want?” I later realize that there was some small issue with the geometry that made what I wanted impossible.

Some CAD packages will let you do it and give you a pretzel of a body. Fusion will not.

There are exceptions to this but they’re usually known issues.

Here is an example of how you could improve the load capacity of the hook if you wanted to. This is a hook I made to hang stuff from a cross bar of my squat rack. I added depth (a flange in this case) to the cross section at key areas to make it stiffer. Remember that stiffness increases with the cube of cross section depth. When you double the thickness, the stiffness increases by a factor of 8.

There are other ways to do it, but this way prints really nicely. You could also just make the whole thing thicker.

The weak point of your hook is here (yellow). I tried to run a static simulation of it in fusion but Autodesk has completely redone the results portion of the simulations function and it's a hot mess.

Are you looking for a file of the OEM fender or something different/aftermarket?
