Why does the Sketchup geolocation create a different orientation than Google Earth, when previewed in Google Earth

[wowo.sketchup]

When creating my layouts in Sketchup I require correct orientation and location, and for this I set the plan in place with the Sketchup geolocation function. However, when I then preview in Google Earth and save as KMZ file, the orientation is several degrees incorrect.

How do I know which is the correct orientation - Sketchup or Google earth?

Is there any extension for sketchup that can set the correct orientation for the geolocation layer?

Your suggestions are greatly welcomed. Thanks, Andy

We get our information from Google, so I’d check the Google Earth forums as well.

Ok, Thanks, I will set up a question there.

If your talking rotational degrees…

You can install the Solar North angle extension on Pro, to make it easier to set the Y-axis to a real world compass point.
Window (menu) > Extension Warehouse
Go to the SketchUp Team page, and scroll down to SolarNorth and install it.

Then (in SketchUp) upon first install, the Solar North toolbar will be opened.

Hi Dan, thank you for the suggestion, I have done that now, but am still uncertain where the true north is. It seems the Solar North tool just gets set to whatever angle I attribute to it. As I’m working from what appear to be incorrectly orientated maps, I’m still unsure how to orient my plans in sketchup to north.

Via the setting you are really setting what the model’s Y-axis varies from true north.

@wowo.sketchup

There are two ways to geo-locate a SketchUp model.
True north in relation to the SU world axes will vary, depending upon which one you use.
It’s impossible to help you set things right unless you tell us in certain terms what you’re doing.

Which method of geo-location did you use?
• File > Geo-location >Add Location ?
• Window > Model Info > Advanced Settings > Set Manual Location ?

Aligning axes accurately with solar north direction

I used geolocation for my model and solar north is not aligned with original axes of the model. I don’t want to rotate the solar north because it will result in inaccurate shadows, so i tried to rotate the original axes to be aligned with the solar north, but i can’t snap the axes to the solar north, and i don’t know exactly the angle between them. is there is anything to deal with this???

MAC: Best practice to geolocate models and keep everything square in layout-

There must be a better way. What is best practice for geolocating your model? Typically, after starting my model at the origin square with Sketchup I use Geo-location, Add location. Then I place my model in the terrain rotating and raising or lowering the model group relative to the Google Earth layers, as needed. But then views like front, right, etcetera no longer work and in Layout everything is rotated in relation to the view ports. I can’t seem to figure out how to correctly locate my…

I just did a little experiment with location ‘Golden Gate’ and some geometry in full length of the bridge.

The preview seems correct in Google Earth. And the orange solar north differs 0.319 degrees (counterclockwise) from SketchUp’s north (system green).
Also the meridian seems to have the same direction as SketchUp’s green.

Note: compass/magnetic north would not be useful (= varies depending on ones location on earth)

@wowo.sketchup: so where is your location that you get a differens of several degrees.
