With manual drawing you have to picture the views, correctly, and then put
that on paper. Again, if you do that wrong, the drawing is wrong and that
translates to your project being wrong.

That is a good argument for drawing by hand... you've built the object
already in your head so when you move to the shop and materials it's the 2nd
time you've built it.

So you have to spend more time playing 3-D chess that in the shop
doing? ;-)
