Much thanks for your reply, the article is really helpful, first time to know there’re two type formats of fbx file.
Due to 3dsMax can read .skp directly, I save skp file to skecthup 8 (my 3dsMax is 2013, the version of skp must lower than max), import to 3dsMax, then export as fbx file (Max can choose binary or ASCII format).
However, neither export ASCII nor binary format, console always shows material export failed.
Our engineer is using FBX SDK for web page dev, so I have to export fbx format.
Cleaning up and correcting model is really cost lots of time and frustrating, especially only have one night to find out where the problem is.
Hope Trimble team can improve these issues in next two or three version.
I was sent a PM asking about my discussion which you linked to above?
Yes, they promised to look at it. No, they didn’t so far as I can tell. SketchUp “Pro” as of 2020.02 still thinks that a cube has 72 vertices, if you export to FBX.
I’m afraid that SketchUp simply doesn’t have the precision needed in a professional engineering tool, so we stopped recommending it to our clients a year or two ago. I was also very disappointed with the quality of responses on the forum. A very poor understanding of basic computer science was displayed. I expected better for a “Pro” non-free tool.
Just to clarify, when I said “72 vertices” I mean 72 values in the vertices list. The actual number of 3D vertices is that number /3, i.e. 24 3D vertices.
Basically it exports the cube as 6 quad faces, polygon soup style, every bit as bad as STL, being too dumb to recognize common vertices. The OBJ exporter does it correctly: a cube has 6 3D vertices, each one shared by three connected faces.
