Hello Lisp Nerds. could anyone help me find Distances from Shuttering plate to Tendon Outer Lines. my requiremtns are Dist 1 & Dist 2. Center line of WEB & shuttering will be polyline & it may has curves as the bridge goes. i wish to take C/L of WEB as reference line and make DIST 1 & DIST 2 at every 1meter intervals. we have a lisp that gives vertical distance between Shuttering and Tendon Outer lines. but we want it Perpendicular to shuttering.. Could anyone help me? i have attached that Lisp too.

I am fairly new to 3D and am having problems with a curved overpass. It begins at ground level and curves both in plan but also elevation to reach 9m at its highest point. I just cant work out the concept of creating such a form. Anny help would be much appreciated You can see the plan of the bridge in front of the 3D structure. Thank you Bridge.dwg
