anyone know how to stretch a aerial to points in LDD? Z wise
I'm not sure, but I don't think anyone does this in Autocad. It requires stereoscopic image analysis, which is way, way beyond the scope of Autocad. The only people I know who do this use some software package or other specifically designed for this task. It can then output information in a form that can be loaded into Autocad.
Warning: I haven't ever done any aerial stuff myself, so what I'm saying here is kind of off-the-cuff...
BTW, what exactly do you mean in your original question? Are you looking specifically for help in using that Delorme stuff, or did you have something more general in mind?
