Thanks. I did write a function cuboid, then 3dLine for joining two points, then 3dLines for more points.
I do create an asy file with your function saveTrianglesAsASY, then I include the scene.pre in the LaTeX file. So far, everything works fine. My last problem is that I did not manage to get the starting view I want. It seems very simple, but it does not work. To find what is wrong, I simply draw a cube from point (0,0,0) to (1,1,1), all edge 1. I want the center of the rotation to be at the center of the object, so I set 3Dcoo = 0.5 0.5 0.5 Then I want the camera to be at point 3 -1 2, so I set 3Dc2c = 2.5 -1.5 1.5 to set the axe of the vector ; and 3Droo=3 for the distance between 3Dcoo and 3Dc2c. But I guess that I did not understand something since it does not work at all... Any idea of what is wrong ?
