Editing FBX file

[l.cariouVF6EP]

Hi everyone,

I bought from Turbosquid a 3D model (crane). I have 2 versions FBX and OBJ.

I am facing the same issue with both formats.

I import it in Fusion.

I have a tri mesh file of the complete crane. With mesh palette tool by clicking a triagle and expand button I am able to separate the crane in different components.

Component attached is composed of 2086 triangles.

Then I convert each component from Mesh to BRep. It appears as not closed. I repair with 'stitch' and 'face' operations.

Object is now a solid (body).

In 'Path' mode i merged triangles to get nice faces to work with. I did it on 1 side only on file enclosed.

My issue is that in 'Model' mode I cannot create sketch on that merged faces.

Can you tell me if I do something wrong.

If I cannot have an editable model with FBX file which file type I should look for? My need is to modify the model ( create shell, add features like extrusion and so).

Thanks

Hi,

I have exactly the same problem.

I bought a 3d car design from Highend3D to make edit, variations but no chance at all to edit either .obj or .fbx file with Fusion360.

I would love to know how to edit. Please help...

Best

Both of you should have done some basic research before downloading and particularly paying for data. Data comes in different formats and might contain different types.

@l.cariouVF6EP The crane part is a triangulated mesh and not really a proper CAD model. There is not much you can do with it in Fuiosn 360. You can convert it into a solid body BRep as you've already done, but it's still very low quality triangulated data. There's really not much you can do with it in Fusion 360 or in general as real CAD goes. To make the edits you are likely looking for this should have been available in a CAD exchange format e.e. IGES, STEP or SAT to name a few. Al of the later contain BRep and NURBS data.

Both .fbx and .obj files can contain meshes but not al meshes are equal. The holy grail of meshes are the quad meshes that constitute the control cage of the objects designed in Maya, Blender, 3DS Max, Cinema 4D, Modo etc. Those can be converted in Fusion 360 into a T-Spine and then edited with the aT-Spline tools

@Anonymous you might have more luck with the car. Vehicles are often modeled in Sub-D modelers ad your model mach come as a quad mesh.

Hi,

Thanks for you feedback TrippyLighting. In definitive I will have to do some reverse engineering and use current mesh body as a template.

Lot of work in perspective...

Any site to download correct CAD files to propose (free or not)?

Yes, Grabcad.
