Footleg This was one of my early challenges shortly after discovering Therion, and it crops up from time to time on this forum. I have decided that with 'draw once, use many times' I am limited to about half an order of magnitude difference in scales (ie 1:500 to 1:2000) to get label spacing and symbol placement that is more or less OK at a range of scales. Personally, once I get to 1:5000 I pretty much turn off all symbols. http://therion.speleo.sk/wiki/doku.php/templates Judicious use of text scales xs, s, m, l, xl allows one to crudely hide minor text at smaller scales. You can use base-scale to globally reduce all text and symbol sizes. Thomas Holders examples show how symbols can be made to plot to suit the scale. Ie hide smaller symbols. http://therion.speleo.sk/wiki/doku.php/metapost?s[]=thomas#scale_dependant_v isualization_of_symbols <http://therion.speleo.sk/wiki/doku.php/metapost?s%5b%5d=thomas#scale_depend ant_visualization_of_symbols> People have proposed various 'dual scrap' scenarios, but it seems to defeat what simplicity Therion has :) You could use 'revise' for each symbol, but I think madness would lie down that route. Check the wiki.

I want to be able to produce a very detailed survey (using a scale of around 1:500) but also to output a complete system drawing at a scale more suited to a large map (say 1:5000). I find symbols getting rendered larger than the passage widths (which seems odd as unless people have much larger passages than me in their caves, I would expect symbols to be limited to a sensible scale for a typical large passage, or omitted?). But also text labels are so large that they obscure entire areas of the cave at the 1:5000 scale. Any tips and tricks for how to draw once, use twice? Or do I really need to maintain two copies of every scrap? Is there a way to draw some detail on a scrap for 1:5000 type scale, and then augment it with fine details for rendering at 1:500 by adding a second scrap for the labels and symbols? Footleg
