Though this is an older post and I am wondering if a solution has been found.
This is an issue for me also when creating architectural drawings that are geo-located, and wishing to dimension them in Layout,
My current work around is the following workflow
- Geo-Location -> Add Location
- Measure angular offset (A) of a dominant axis of the building floorplan (as seen in the Google Earth Satelite Image) from the Sketchup default Y-Axis
- Make a copy of the Geo-Location Images, and rotate these by the negative angle from previous step (-A). These can now be used for tracing the floorplan etc
- Adjust Solar north by an angle of (-A)
Now I can get orthographic dimensions in layout for the standard views ( but not for any aligned views unfortunately)
Solar North will be correct, as will be Latitude and Longitude.
Drawbacks are the hassle of this workaround and the fact that I am only to get orthographic dimensions from the standard 6 views, whereas elevations offset from these are quite common.
See below for a simplified example showing the problem.
The red box has been drawn with the axis at default orientation, the green box was drawn with axes rotated 30degrees from the standard axis orientation.
The first view is a standard front view using parallel projection, and all orthographic dimensions are correct.
The second view has been aligned to the green front face, and is also a parallel projection. This view also has Ortho activated in the model settings in layout. Note that the red box shows 3d dimensions and not orthographic
