it woks when you only use "texture" for the 3d model (doesn't work if you change a color)
Thanks for all

in this line for example :
"v -60.698318 69.639313 141.979401 0 0 0"
how many values and wich numbers can i remove ?
how did you found the wrong lines in my 3d model ?

thanks

Ah... how can i check my 3d model with a text format ?

it seems that the problem arises as soon as you add colors to the model in 3D builder.
A simple shape without color does not pose a problem and is imported without error into 3D sweethome.

Thanks for your help.
I send you a 3d model wich it makes an import error in sweethome

Impossible to import a 3d furniture created with 3D BUILDER (windows 10) en .OBJ, it worked well before, but now the import only works with a 3d .DAE model that removes colors and textures ....

Thanks for your help
