kob Posted February 29, 2012 Share Posted February 29, 2012 Need help doing road profiles and cross sections. Can anyone suggest where I might find instructions or book explaining. Thank you. Quote Link to comment Share on other sites More sharing options...
ScribbleJ Posted February 29, 2012 Share Posted February 29, 2012 For AutoCad 2004; would be to use LandDevelopement Desktop (or LDD). To do it in vanilla AutoCad would be a task that is very time consuming and tedious. I have never seen any books explaining how to do so outside of LDD. There are quite a few elements that would go into determining all of the known parts (and unknown parts) to generate profiles and cross-sections. You're horizontal alignment is the very beginning point. Then you must determine all the elevations at the various points of the existing grade to start working on the profile. The cross-sections would come afterwards once you determined the interval of each one. Then the elevation process for each cross-section would have to be determined based on the elevation at that point on the profile and then carrying your cross slopes along the cross-section in each direction (left and right of the alignment) to determine what the elevations would be for each cardinal point of the cross-section. I could go on but you get the gist of it I hope. This is why LDD or Civil 3D would be necessary to keep it from becoming a monumental task. Come to think of it; it is amazing to think that this is how it was done before the advent of CADD. Each part was thought out on paper and was all done by hand; calculations and drawing or each part. By the way; Welcome to CADTutor. Quote Link to comment Share on other sites More sharing options...

BIGAL Posted March 1, 2012 Share Posted March 1, 2012 Before CIV3d and LDDthere was alternative dedicated software at least 20+ years ago now and even then in some cases was smarter and lees complicated than autocad is now ! Quote Link to comment Share on other sites More sharing options...
