Hi!

Has anybody got any suggestions I can try for making my new circuit diagrams a bit smaller but still readable please?

I tried to draw out the circuit of the Vertical Channel of the Russian C1-112A Oscilloscope/Multimeter combination using my sPlan 7 and it still sprawled out to over 550 mm long, far too inconvenient to print cheaply !

To take an example, how do SE Labs/EMI do it – I think they can get a Vertical Oscilloscope Channel on one A4 sheet, including attenuator circuits, but I certainly can't !

Is it my symbol sizes are possibly too large, or am I using too large a lettering size, resulting in symbols having to be spaced too far apart?

I letter my diagrams in UNO Stencil Alphabet Upright BU for the component References, 3 mm high, Uno Stencil Alphabet Condensed BC, 3 mm high, for the component values, text notes are Uno BC, 3 mm high, and voltage readings/PCB external connections are Uno Stencil Alphabet Sloping BS, 2.5 mm high.

(These standards were adopted from Thorn/BRC service manuals as a standard for British commercial good practice).
