lanvin Posted October 9, 2008 Share Posted October 9, 2008 Hello, i'm new here and desparately in need of advice. i have plotted a 1 to 1 scale longitudinal section view of a river tributary of 3000m and the total difference from headwater to confluence is 17m in elevation. So i need to 'squeeze' the 3000m into a drawing, which means scaling it down. However, i would like to maintain the elevation so that the profile is clearer. Is there anyway of doin' this? i mean maintaining a Y of 1 to 1 scale, and X for example 1 to 10 or 1 to 100 scale. I know the easiest way is to redraw, but i do not want to waste the time for the sake of one drawing, since i still need the 1to 1 scale drawing for my hydraulic modelling. Please advice and thanks in advance. Quote Link to comment Share on other sites More sharing options...
ReMark Posted October 9, 2008 Share Posted October 9, 2008 You could WBlock out the profile(?) then Insert it into a new drawing specifying a different X, Y or Z scale. I think that would work. Not sure if you would actually be pleased with the results. Quote Link to comment Share on other sites More sharing options...
Tiger Posted October 9, 2008 Share Posted October 9, 2008 It works with the simple BLOCK command as well; I do it like this, step by step Select all the entities Ctrl+Shift+C - select basepoint Ctrl+Shift+V - select insertion point Mark the new block - Open up Properties and change the Y-scale in there. The only thing I have found that messes this up is that the original Polylines are all converted to Lines when I explode the block again...

Patrick Hughes Posted October 9, 2008 Share Posted October 9, 2008 Here is a totally novel approach if the other methods are not satisfactory: Set your view "on edge" so you are looking at the "front elevation" of the 2d section - do this by the command sequence: UCS X 90 PLAN Now you are looking "on edge" and you should see only a line. Rotate your geometry to produce the "x" scale you need 1:10 = 84.2608 %%d 1:100 = 89.4270%%d Set your ucs back to world, view PLAN, now issue the "Flatten" command Quote Link to comment Share on other sites More sharing options...
