WagglyFawn Posted April 24, 2008 Share Posted April 24, 2008 Can you give us more details? Quote Link to comment Share on other sites More sharing options...
Julie@Integra Posted April 24, 2008 Share Posted April 24, 2008 What, specifically, are you not understanding? What should be shown? Or what "cross-section" means? Can we see a plan view... or whatever you've got to represent what you're needing a cross-section of? Do you need a crude line representation, or a [semi-]realistic rendering? Not sure I can be of assistance but even if I can't, this is the kind of info anyone would need in order to help you. Quote Link to comment Share on other sites More sharing options...
fresh Posted April 24, 2008 Author Share Posted April 24, 2008 hiya, 2.zip is the section ive been given. on another drawing i also have the heights of the river bed and the heights of the tube lines running beneath it. i have just been told to come up with a cross section of these drawings. what i dont understand tho is, the other drawing, (tube lines) have the same heights so the lines on the section showing them would effectively be overlapping! is this right? sorry for being a doughnut! (dumb) thank you 2.zip tube.dwg Quote Link to comment Share on other sites More sharing options...
Guest Alan Cullen Posted April 24, 2008 Share Posted April 24, 2008 Without looking at your drawings. Cross sections are normaly drawn at a 1:1 distortion, so if this is a one off job, then very easy. you say the crossing strings are 3D, I hope so, because this will not work if they are not. Draw a line (line A) "through a footpath, stairs, bank of a river, river bed and a few tube lines underneath" Then go and ID each elevation of the lines that are crossed, this will be your elevation (level) of the relevant points. Then go back and measure along the line A to each of those points, that will be your distance. Why am I doing this???? The sun is about to come up...... anyway, you now have a distance and a level for each point. now...go to acad, and draw a polyline. enter the fist point as the first point, i.e. X,Y, where the X = distance and Y = level. then keep going and enter the next distance,level.... then the next distance,level. And when you finish, you will have your cross section. Quote Link to comment Share on other sites More sharing options...
rustysilo Posted April 24, 2008 Share Posted April 24, 2008 I suppose the first order of business would be to figure out what units you are to be working in. The 2.dwg is set up unitless, but dims appear to be metric units. The tube drawing is set up for inches, but isn't called out in the dwg. Secondly, be sure everything is to proper scale. Then you can move forward with the rest. Quote Link to comment Share on other sites More sharing options...
