Workflow for reverse engineering scanned part

jordy_keller — Thu, 30 Jan 2025 17:47:37 GMT

EDIT:

I attached the STL file. In fusion I use place mesh to import it.

I don't have a post-worthy result in fusion yet so just the STL for now

/EDIT

Hi,

This is my first time trying to use Fusion to model a clean part from a 3D scan. I would like to your opinions on which workflow / tool to use. Forms, surface modelling, creating cross sections and lofting... I know there are a lot of videos on these topics but I'm not sure what tool is best suited.

I think I'd rather not use forms though, compared to blender it seems a bit limited, but that might be just a first impression.

I want to use the created part to use as a reference, model upon and perform boolean or cut operations.

This is my scan:

Hi,

I would strongly recommend that you do the embedded tutorials in the Fusion Documentation and also some of the

Self-Paced Learning to help you to learn fusion faster and better. They can be found here:

It is also much easier for the forum to help you if you attach your file AND a screenshot of what you want to achieve

and what the problem is. You can create a file to export like this:

Time spent on the tutorials and self paced learning will not be wasted. Also check out the three RULES that are pinned to the forum for further guidance. (credit : @Drewpan )

If your also planning on using Fusion for the forseeable future I would advice watching "learning Fusion in 30 days" which can be quickly watched in a few hours with full conceptual knowledge, and there are also people on the forum who have youtube channels who can guide you like TheCadWhisperer, and Peter Doering.

For this project of yours, forms would be the right option, and while it is generally more limited than blender in my opinion, this could probably be created using the form tool (T-spline) a starting rectangle with maybe 10 faces up and 2 side, and edit as neccessary with the edit edge tool to create wanted shape.

If you don't want to go through the pain of using forms as your new to Fusion, would be to use surface modelling, as it primarily uses sketches, which if you have prior CAD knowledge, you should be famuliar with. You can sketch the shape of the object, and use the surface modelling tool to patch the sides and thicken to make the desired object.

If your require help or assistance, please don't hesitate to ask questions, and if so can you please give some measurements to your piece and a few more screenshots to see the whole model, so other people in the forum can also assist to a better extent

Sleepy Regards

Ricky

Ricky, thanks for your elaborate reply, good info.

Just a quick reply for now but I will look into your suggestions.

Thnx

No problem, is there any way that the 3d scan can be attatched to the forum for further inspection, as this may also be a model that can just be lofted quickly instead of spending quite a while using surface modelling with patch tool or T-splining for someone new to Fusion.

Just a suggestion...

Please attach your model? If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

This would be a relatively simple surface modeling exercise. I would use the mesh only as a visual aid.

Can you share the scan data? If so, zip and attach to a post.

I just attached the STL file in the opening post.

Thanks for the feedback so far
