You can do the same thing with Sketchup, and can even paste your own photos onto stuff.

Or you can take a picture of a building, then use an add on program to calculate where the picture was taken from, and actually draw the building from that, no need to enter the dimensions.

There's a lot more Sketchup models out that you can download than there are for Solidworks, I daresay Solidwiorks is ultimately better but usually it is very expensive too, so the user base is much smaller.
