Patent Drawings are extremely easy in Sketchup Layout compared to other applications. A quick example can be seen here: How To Make Patent Drawings In Sketchup
Sketchup already supports the process of making patent drawings. Document Size, Margins, Text, Arrows, Lead Lines etc. Why not add some basic features to make it even easier?
1. Add additional document ‘margin options’ specifically for patent drawings. So a user can check a box for Patent Margins and the margin dimensions automatically apply to the document.
2. Add additional Layout Style called “Shade Lines”. This is the same as the ‘Hidden Line’ style, but it automatically adds the shade lines to an object.
