I am advising on modus operandi for a client with an unusual need. They want to place photomaps in CAD and then draw detail on it for their race structures etc. I have found that when I scale-up an inserted photomap (derived from Google Maps) to life size, there are many problems of zooming in and panning. Very often the image area becomes just a white rectangle or other times a black solid rectangle. Regen has no effect. A bit of a nudge with the mouse wheel to zoom out a bit sometimes makes it appear. But it is not good enough to do work with.
A possible remedy might be to go for less than 1:1 life size in Modelspace but that brings difficulties measuring features.
This behaviour might depend on the computer of course. Mine is Win7 32-bit with 4Gb RAM and Nvidia Geforce graphics with 128Mb dedicated graphics RAM.
The inserted image needs to be scaled-up around 100,000 times or so and is quite large in area to start with. My try-out job is a map covering from Frankston to St Kilda.
Any advice?
