Scaling multiple imported images


I’m hoping someone can help me out with scaling multiple imported images. I’m working on a 2D sketch with multiple floor levels (3) in the floorpan and they are all on separate PDFs. I only know the length of one area on one of the floors, where as the other 2 floorplans have no know measurements. Is there a way to get them all on one file in sketch-up under the same scale?

Thanks in advance!


If you resize the one with the known dimension you should be able to find something–an exterior wall, perhaps-- that is common in all the images that you can measure and use for resizing the other images.
