I have had limited success with modelling a site plan. Many times, I do not have a survey, so I "wing it" estimating contour lines and trying to get something "close enough" for a 3-D presentation. I inform my clients that I am not responsible for site improvements, unless they get a topo survey. Most opt out.
I now have a high end client on a very steep site and he did commission a topo survey. I have modelled the site (a laborious process) but have many questions as to how SP users use the site in their model?
Right away I see a challenge as the building's "plan north" is about 15 degrees off of true north. Not sure if I have to rotate the entire site? Or is there a way to reconcile the floor plans with the site plan and show the floor plans oriented at "plan North" and the site plan oriented at "True North".
So, what methods have users found to best utilize the site plan in 3-D?
