Hello, I encountered a problem while creating a 3D model using Google Solar API. When i turn on the terrain model it elevates my already existing 3D object and all in all shows differently than it's supposed to be. Maybe I'm missing something, but i don't know.

It's supposed to look like this, but...

I

Instead it looks like this:

It kind of generates the original building copied off the google maps under my 3D structure and if I choose the option of cutting out the terrain model it only does this around my structure (as it says so) and if i decrease the overall height of the building to 0 (using the "Proper height" button) - it looks good but i fear it may hinder the preciseness of shading simulation.
How it looks with 0 height:

Overall my question is - is there a more elegant and precise way to generate terrain model excluding the terrain under my building?

I would be very glad for an answer! :)

Thanks

Dear Goldman,

Thank you for your inquiry.

From our point of view, your planning method is correct. We would describe the planning steps as follows:

• import/download Google Solar API orthophoto and elevation data for the site
• define elevation 0 (set pin)
• draw polygon for the building (make sure that the corner points of the polygon are actually on the roof of the building, not on a tree overhanging the roof, the ‘show elevation data’ button helps here)

• if necessary, make the polygon perpendicular
• extrude the building
• adjust the building dimensions (right-click on the building --> ‘edit’) if the polygon had to be drawn smaller due to overhanging trees
• make sure that under ‘options‘ --> ‘height data‘ the check mark for ‘cut out the terrain model around the polygons and extruded 3D objects‘ is set, with an additional space of approx. 1 m

• alternatively, if you need any additional distance, draw a polygon, but do not extrude it

• activate terrain model (lift mode)

If the lift height is distorted by the overhanging trees, the height must be corrected subsequently (right-click on the building --> ‘correct height‘).
