Following design instruction serves the standardized creation of symbols, usable in different scales.

Create single symbols with a size of 100x100 mm up to 150x150 mm as symbol's outer frame.

Then symbols are clearly visible when using scales up to 1:100.

Create groups of symbols or combined symbols accordingly to their outer frame, which is up to ten times greater, with 1000x1000 to 1500x1500 mm.

Keep the line thickness as small as possible, so that the symbols are clearly visible with a scale of 1:1 and in addition do not blur in a single spot.
