I drew this trackside junction box from a photograph in Adobe Illustrator. There’s a lot more planning involved in the process and mapping out shapes with the pen tool seems more like cutting shapes for a collage than drawing.
So far manipulating anchor points on the outlines of shapes seems rather random to me. I find it easy to inadvertently delete an anchor point and lose a section of the shape. Converting between an anchor that results in a straight line and one that results in a curve seems equally obscure.
The only way that I’ll learn is to keep practising.
