Create a shell around an imported 3D object

Anonymous — Tue, 08 Jan 2019 01:01:17 GMT

Hi,

I am a hobbyist trying to import a 3D scanned object into fusion from the MSoft scanning software. I would like to then create a shell design around that object that can be taken on and off. . Can someone help me with this process. Thank you!

What is the nature of the object after you have imported it? Is it a solid, a mesh, surfaces? I’m not sure what you mean by shell- do you mean you want to make something like a mold for the object? Or just a design that would fit around the object? If the latter, the tools and workflow would be very dependent on the nature of the shape you are trying to wrap around. There are tools in the Sculpt environment that enable fitting sculpted shapes to objects, for instance.

A screenshot or better yet a file posted here (export as .f3d and attach) would enable better suggestions.

Oceanconcepts thank you for your time. I am importing a solid 3D image of a forearm and trying to create a cast that goes around it. I have a friend who needs one and wanted to try this solution. I'm guessing I just need to figure out how to get the 3D images file in that .f3d format? I didn't know if there was a process that would auto wrap or adjust to the 3d image or if I had to manipulate the planes to fit around the forearm. Thanks again!

This is something Fusion is well suited for.

Look at tutorials for the Sculpt environment for how to develop and modify complex organic shapes. If you are in history based modeling environment you access this through the “edit form” option. In direct modeling select Sculpt from the top left pull down.

I'm assuming your son data is coming in as an imported mesh. You can import an organic shape and snap t-spline (sculpt) shapes to it, then thicken or modify at will. They can then be converted to solids for machining, to meshes for 3D printing, etc.

Search in the learning section for working with meshes.

The .f3d file type is just native Fusion, that will provide the file as you have it on your system. It's useful if you are seeking help so others can see exactly what you are working with.

If you post your model or even better the scanned data (zip it first) then I am sure we can help you.

Scanned data is usually only available in dense triangulated data. There are a few hurdles to take to get this data into usable format, but we can help with that.
