How do I do to draw a box or a rectangular section pipe of length l?
Hello everyone!
I would like to draw the attached graph in 3D with Mathcad 15. It seems to me that this problem has already been addressed in the community but I cannot find it. In fact, it is a rather arduous job although from the geometric point of view it is a question of tracing flat surfaces orthogonal two by two. To do this, I downloaded and installed "images14.exe" and also the list of the functions contained, but I don't know how to use it. How can I avoid using these functions? Could anyone help me? I thank him infinitely.
