I am in the process of modeling a FM road project for some dirt quantities. Since we don’t have much for the side slope transitions. I was going to CAD Cross Section the side slopes. First, I should have verified that the cross sections had the right elevations and they don’t. I verified after I created the slopes from CAD PDF. I was then verifying my converted 3D linestring offset from my alignment. My right side matches my offsets. The left side does not. I would have said o well, cause I can not use them since elevations are wrong. I still want to know why the linestrings are on the wrong offset.
To verify the cross section I went ahead and import a few sheets to digitize and yup, the CAD linestrings are wrong on the left side. The blue lines are the CAD and the white is the digitize lines.
ICAD PDF Cross Sections.vce (15.7 MB) deas why they are wrong?
