J. de Waal has redrawn several of my drawings to put them into his format, and make them metric.
I don't care for the holes in the flywheel that he sometimes adds, but I am sure many like that sort of thing.
I don't like his extremely crowded drawing format either, but others like that too.
I sent de Waal an email and asked him to please stop coying my drawings, and make his own drawings and engines.
I have not seen him copy any of my material since I sent that email (perhaps a year ago), so perhaps he will stop.
de Waal has a big following in the hobby community, and I respect that, but a lot of it is not his original material, but rather drawings that someone else has gone to great lengths to produce.
There are many models on Grabcad that were built using de Waal's drawings, but actually they are drawings de Waal got from me.
The problem is that the credit always goes to de Waal, as if he had created the drawings originally.
So whether intentional or not, de Waal coop's my drawings and designs for his own purposes.
I am ignoring what de Waal has copied to date as far as my drawings, but he should not use any more of my drawings, since I have a copyright on my drawings that states "for non-commercial use only", and he advertises his drafting service on his drawings which he creates from mine, which is a commercial purpose, and a direct violation of my copyright.
The "designer drafter unknown" on his drawings would be me.
It is very disturbing for me to go to Grabcad, type in "steam engine", and see so many of my engine designs attributed to de Waal; its just not right.
