This led me to think about what we have today in terms of drawing aids and tools. take for example the Grid Technique. It has been used by Rubens, as evidenced in his drawings.

All of the above tools help us with our drawing and painting. But these tools are not new, we are talking hundreds of years.
The romantic notion that true artists just sit there in a kind of trance and deliver outstanding drawing and paintings is just not true. Ask an artist! This perception by the general public makes many new comers and seasoned artists think that they are "cheating" if they use any kind of tool to help them with their artwork.
Creating art is not about the tools, but about what the artist is trying to communicate, their joy with the colours or form of a subject, texture etc. If the tools exist which could help the artist in the process of their artwork, there should be no reason why they cannot be employed.
Don't be put off by what people might think about how you created you artwork. If you enjoyed creating it then the creation process has achieved its aim.
Enjoy your art however you do it because it doesn't matter how you create it!
