Importing FBX files to convert to Solid

Enes.Erdem — Thu, 06 Feb 2020 21:42:03 GMT

Hi guys,

I have an DWG file within an navisworks export (FBX).

I would like to convert all the meshes to 3D solid for smoother work and for creating 2D drawing (FLATSHOT).

Now if you can see in the attached DWG file, i have a lot of lines and faces. Is there an option to convert the model to 3D blocks.

Thank you for your help.

Hi,

even if you would be able to convert it to solids, you would not get smooth/round objects, these are all segmented.

I would strongly recommend to get the source geometry/the original files before they landed in NavisWorks.

Hi alfred,

Thanks for your reply,

I've added the source file. That is the FBX export from navisworks. You can see that the surfaces there are smooth and solid. Converting / importing in Autocad is the problem i think. Is there any solution for converting to smooth 3D faces or maybe some converting between navisworks and autocad.

Hi,

FBX is already an export of some other software, it's really necessary to get the source, not a file that is already converted from another software.

>> You can see that the surfaces there are smooth and solid

Why do you think they are solid?

If an object is displayed smooth it can be a simple setting of the shader (to show neighbored faces in a smooth way so you can't see the edge between the faces, but that does not mean it's not segmented)

Thanks i understand it now.

So.. there is no solution for this i think. Because the files (Navisworks) is recieved from the client. I've to work with that kind of information/files. There is no option to recieve the source file.

How to reduce the file size and optimize the (faced 3D model) dwg drawing in my first post. Is there any option.

Hi,

And you can't ask the client to get the original geometry?

Anyway, what is the real goal you have to do with this geometry?

Just to create views does not mean you have to convert the mesh.

You might also use command _CONVTOSURFACE (make sure first to first set SMOOTHMESHCONVERT to 3), then you can activate a layout and use the _VIEWBASE command (and it's options to get different views and sections of your objects.

Hi again,

well, not sure if CONVTOSURFACE is the way you really should go.

I tried to convert the meshes to surfaces, the dwg-file has now >1GB ... creating _VIEWBASE objects was possible (was really surprised about this), but I guess it's really hard to handle this file size with AutoCAD.

Let's see what you really have to do with this geometry...

That's how it currently looks like 😉
