Adjust paper size to selection
This function allows you to resize the paper visually. This feature makes it easier to crop your drawing.
To change the crop:
•With the Selection tool select the rectangular area that will be the new crop.
•On the Edit menu, click Adjust paper size to selection.
Important notes:
This function does not remove the drawing from the new cropping area, but simply changes the rectangle of the paper. You can change this area again and find all or part of the drawing that you have hidden.
In the same way, the brush strokes carried out outside the area of the paper are still recorded by the application. This makes it possible to reveal these drawings when the area of the paper is enlarged.
So in summary, you do not have to worry about the initial framing of your drawing. The final framing and dimension of the drawing are decisions you can take a posteriori.
