Since I am tempted, I'll just open my fat mouth.
Since neither you nor the kids has C3D at your disposal, then teach them the long way of finding/recognizing PCs and PTs and how to determine all the data and draft and label it properly. Then just tell them that C3D can label it all automatically. DO NOT write something for them! I don't know how you learned to ride a bike, but I skinned my knees plenty. Ya can't leave the training wheels on; they're for little kids.
Plus, if you know your C3D well enough to teach it, then get your department head to subscribe; you teach it; you will be worth more, and so will the kids.
