Showing results for tags 'contour z value'.
Well i have a homework for the university , im working in AutoCAD 2006 , so the project is that, i have a pdf with contours of an area, i have to rasterize it as a jpg picture, pass it to AutoCAD (i have done this so far..) and then i have to find the X , Y and Z coordinates of some points in the picture. Well with the "ID" command, i found the X and Y coordinates but as Z it gives me 0,0000.. How can i pick a point in the jpg and find the Z? I have to find the altitude! (Does i have to make something called georeference?) help!!!! Please guys help!!! (((
Could someone help point me in the right direction here? I want to filter a selection of polylines (contour lines) by their Z value (ie filter to get only 10' or 5' or 2' contours). I assume I need to test the Z value to see if it is a muliple of 10, 5 or 2, etc... Any hints on hhow to get this sarted? Thanks
