Tutorial in 3D modelling in Bricscad?

Is there a tutorial for starting a new person to use BricsCad 3D symbol drawing?

It is not needed for advanced use of the 3D, but just the basic functions, mainly cube and cylinder objects.

Joining and subtracting entities are going to be used.

It is for a college of mine who has no 3D experience ....

NB: We are using BricsCad V13 for the training.
