the cadtools manual is very specific in most cases. please refer to the manual for further description of the functions and their options. These are the basic steps of using cadtools. use surface profile and surface cross-sections by loading existing and design surfaces and choosing the alignment create a contour polyline from the embankment line and use the function delete triangles with centroid outside polygon from the edit surface menuġ5. create a surface from the design lines : axle, carriageway and embankment line and be sure to check use polylines as break linesġ3. use create longitudinal features to create the intersection with the terrain ditches can be created automatically for cut zones and with offset 3d polyline for fill sectionsġ2. use offset 3dpolyline from lines menu to create the carriageway ġ1. choose "create 3d alignment" form lines menu and you create the 3d axle of the road ġ0. design your vertical alignment on the profile ( the one with no vertical exaggeration)ĩ. profile 3d polyline : function found in lines menu tip: plot the profile with 10 vertical exaggeration for guidance and 1 for work ħ. drape polyline : open edit surface, load saved triangulation (tsd file) and use drape polyline function Ħ. join the alignments segments into a polyline tip: check for the direction of the polyline and if it's not the right way use reverse polyline from the lines menu ĥ. PSAS LMS is a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create. create your alignment with lines and fillets ģ. tip: verify the triangulation result and just then export to. create "existing" surface from your data (check for the type of data you can use) -> create surface. but I can give you a short list of things to be done (I'll assume that you can find the functions and that you have knowledge about road working with 3d design software):ġ. and unfortunately it's going to be stuck there for a long time. Creating a video tutorial for road design in cadtools has been on my agenda for a very long time.
