Ruler issue. Potential Aid.
My students are using Autodesk Sketchbook pro to create freehand sketches, isometric and orthographic projection drawings. This is the only software on the Windows 10 platform that is similar to drawing on paper, is free of charge and not computer resource hungry.
The lack of a ruler was/is a pain in the neck. However, if you have a problem, you don't stop, you improvise, adapt and overcome it.
An A3 sized paper is 420mm in length and 297mm in height. It will have 4956 pixels wide by 3504 pixels in height. This is based on a canvas that has 300dpi. Every 10mm will equal 118 pixels.
If you set your canvas anchor point in the bottom left hand side, that will be set at 0,0.
You have two options - create a layer and draw a ruler onto it (it will be rough). Or find an image of a ruler on the internet and insert it into another layer and ensure it fits correctly. You can use it to create a drawing with some degree of accuracy.
However, this can take time to set up. Ensure you save the drawing as a template.
Hope its helps.
