Here is a screenshot of part of a construction document which has what I would like to do with the mesh tools contour lines. This page has existing contours and new contours. The new contours are in solid lines and the existing contours are in dashed lines. Take notice how the new contour 375 is bolder than the new contour lines above it. Then, at the 380 new contour line, the line is bold again. So, 376-379 are set to a 95 pen weight and 375 and 380 are set to a 97 pen weight.
In this section of the page, you can see how the new contours kill into the existing contours off to the right of the red text. The existing, in dashes, follow the same idea but instead of a 95, they use a 94 and instead of a 97, they use a 96.
This is drawn in 2D in ArchiCAD, but I would like to get the same effect with the contour lines from the Mesh tool if possible. My question just pertained to getting different line weights with the contour lines, but if you know how I would also get two sets of contour lines, one for existing and one for new, that would be helpful too.
