   Creating coordinates for 2D / 3D objects
  I imagine this is a stupid question, but is there software available which allows one to draw 2D / 3D objects and figure out the coordinates of points.Making them up one by one is extremely tedious.   
  You could use 3D modelling software such as Blender or Maya to model a 3D object, and then export it as a simple 3D file type such as .obj. Then, simply read in the vertex data from your .obj file.
