Any sketchup users?

Quick answer, no.
Long answer, using some sFm software and terrestrial photogrammetry you could extract a nadir ortho-photo, import that into Sketchup then draw your linework. But if you have gone that far, you could just import the ortho photo into a CAD package and get the same results.

sFm software to check out - visualSFM, photoscan, photomodeler, photosynth, catch 123d, pix4d, datumate.

wow

My sketchup workflow is simple: Measure the building, measure to a ridge or two. Photograph everything as close to orthogonal as possible. Bring the images into CAD and align them to the dimensions obtained. Rough out some measurements and draw them in sketchup. Then pull the photos into the sketchup model and tweak as necessary. Not looking for perfection, just a nice representation.
