A very detailed grid should cover the entirety of your document now.Ĭhoose the one you want based on your needs! If none of these are good for what you want, there’s even a ‘Custom’ option! Simply choose it and enter the exact point where you want the Original point of the ruler to be.
Now you have to put up a grid! To do so, go to ‘View -> Grid’. The other document should have the same size and be blank right next to the one with a picture of the painting. Have two opened documents, then choose a painting you like and want to copy. But, it is very possible and even simpler to do digitally! I remember doing this in high school, except it was with traditional art. This is a very common exercise when studying art and how to draw. For example, it is also useful if you’re practicing from paintings and drawing a representation of it! It can be really useful if you’re doing a very big work with a lot of objects and details.
