FBX generating issue
« on: September 26, 2019, 02:48:05 PM »
Hey there !
I'm using a 1.5.4 Metashape professionnal version and I try to generate meshes in fbx format in order to be opened with AutoCAD 2018 (v. O.49.0.0).

My export settings are, local coordinates, no shifting. No cameras, neither markers or normals. Textures in jpeg and the raster encoded in binary encoding.
Because I tryed to open the generated file on CloudCompare or Blender and it worked fine, I wonder if the issue can from Metashape or AutoCAD.

I anyone had a similar problem ?

Hello GGR,

What is the problem when you load the file to AutoCAD? How many polygons are there in the mesh model and what is the resolution of the texture atlas?

Hello Alexey,

Thanks for your reply.

When I import my fbx in AutoCAD, the message "The file cannot be imported because his format isn't supported" pops.
My mesh is not that much big cause it is a 1300k vertices one with a 30k, 4 bands and uint8 texture.
If it may help, I tried to export other meshes in fbx and the result is exactly the same, the format seems to be unsupported.

Thanks by advance.

Hello GGR,

Do you have same problems both with binary and plain text export options?

Do you have any tool that may convert an existing FBX to the older FBX format?

Hello Alexey,

Sorry for the delay.

I followed your advice which was to export my fbx in differents versions (6.1 ascii/binary and 7.5 ascii/binary). The soft I used to do so is FME 2019.1. I also tried to export it with or without local coordinates, but in my opinion it's a deadend. What I noticed so far is 7.5 binary version is not supported on AutoCAD 2018. The 3 others versions are readable, but there is kind of a visualisation problem.

I'm going to contact the AutoCAD support to figure it out. I'll let you know as soon as I'll get info about this.

Regards
Gabriel

Hello Gabriel,

If you have any feedback from AutoCAD support regarding the FBX format specifications that are readable by their application, let me know. We could try to implement the related changes in our export.
