Change thickness on sections of solid model - help

[anisamariam180]

Hi Everyone,

Hoping an expert can explain how to change thickness of individual sections of a solid model in  Fusion 360.  The model has flat areas & some curved/beveled areas. The flat areas are connected with some curved surfaces for transition,  so I need to and adjust the flat surfaces and curved areas that connect them. There is also some text engraving on the flat areas that needs to have its depth remain unchanged.  Appreciate any help!  Step file attached here.  Thank you!

No file is attached.  Please attach your model as a standard Fusion format.  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.

THANKS !  Here is the file in correct format.  I am working with a solid model file (STEP), when making the edits it Fusion.

I attached the f3d file.  Note, in a program like Tinkercad its easy to change thickness of a flat section that has a bevel.  The section appears as one piece and I simply change the thickness of it, and the whole section gets adjusted (including the bevel).  But as a solid model in Fusion, the section is separated into a few  faces (the flat area is a separate section from the bevel).  I can change the thickness of the flat areas by using extrude.  But I don't know how to select the whole section (flat plus bevel) and adjust its total thickness like I did in Tinkercad.  I would think Fusion has a simple way to do this.  (Change thickness of sections that have a mix of flat and curved / beveled areas).  Appreciate any expertise you can share!

Quick update:  I have tried several methods to change the thickness of individual sections in my solid model.  This includes Press Pull, Offset Face, and Extrude.  The Extrude only worked for flat portions, but did not work on beveled/curved areas.  As simple as this sounds, I am not able to figure out how to make these thickness changes to the solid model. As far as I can tell, my solid model is a clean stp file (no-mesh), and should be changeable in Fusion 360.  I have attached a section of the f3d drawing here, which may be easier to work with than the prior file I sent.  Also attached is an image describing the changes I am trying to make.  Mr. Hackney, I'd greatly appreciate any guidance from you or others in the community who have expertise in Fusion.  Thanks!

Hi all, I'm guessing its not feasible to edit this solid model stp file in Fusion, and that it would need to be re-created in Fusion instead in order to make a variation of it.  I was trying to avoid this.  Any suggestions are welcome.  Thanks!

I recommend that you recreate in Fusion and then attach that model here.

Perhaps then someone can explain how you would edit the original file to get to the same condition, as it is, I am not sure of your true Design Intent.

Thanks!  I would need to spend time improving my Fusion skills to create this type of solid model from scratch.  I did the original design in Tinkercad and exported as an STL mesh file.  Someone else took this STL and created the non-mesh solid model STP file. I'm not sure what program they used or how they did it.  To modify that non-mesh solid model, I assumed it could be imported easily into Fusion (regardless of what program created it) and that it could be easily modified for basic things like thickness changes.  Probably more involved than I thought.  I also tried several times to convert my original STL mesh to 3D solid model STEP file (non-mesh) in Fusion, but got many errors, I think due to the complexity of the mesh.  Thanks again for your reply!
