I am using a photo of a house, taken from the corner and out far enough to get all of the building. The photo is taken using iPhone 6. I imported this into Sketchup without any processing/cropping/rotating/etc. When I accurately align my red and green guides (by zooming in on each endpoint and carefully placing them along hard straight lines, my horizon establishes itself fairly accurately, but when I go to place my axis origin, the vertical is noticeably off of vertical with respect to the line of the house. My desire was to use the closest corner as my origin, but it is the corner that least matches the blue axis with the vertical of the building. The other two sides (left and right) are closer, but still off. So, the obvious effect is when I start at my origin to draw my first vertical line to begin mapping geometry to the photo, it’s wrong. I also correctly scaled the grid to actual building measurements.
I have watched the Sketchup Training Series YouTube vids and read the Sketchup Help Center (Matching a photo to a model) material, but in all of these examples, the axis seems to align itself perfectly to the vertical in the photo used after correctly placing the red and green guides.
I can’t seem to find any similar complaints. Any advice? Thanks!
