Use case of transformer Coordinate System Convergence Calculator

Hi @kidega,

I think that would be a great use for the transformer!

I am attaching a workspace that should automatically adjust the Sketchup file to align the original green axis to true north. Please give it a try to see if it work as expected.

Hi @daveatsafe,

I have continued to use your custom workspace above and it has worked very fine. What I am doing now is reading a .kmz file and calculate the rotation which is all good. The problem I have is to write it back to .kmz with a working 3D model when importing to Sketchup. Not sure if it would work to write to sketchup direct as well? In the writer I have set Coordinate system to WGS84.

The source .kmz has coordinate labeled:

CS_NAME: KML COORDSYS 0

DT_NAME: WGS84

So when I compare the readmodel.kmz and WritedModel.kmz, I noticed a difference in Min and Max Extents for x and y values.

Thanks!

Hi @kidega,

I would recommend writing directly to Sketchup instead of KMZ. This way the Sketchup output is completely under FME's control. FME will write the appropriate georeferencing to the Sketchup file.

Hi @daveatsafe,

Just by curiosity.. does your workspace of aligning original green axis to true north, work by rotating each feature's center point, that enters?

Hi @kidega,

The workspace rotates each feature around 0,0,0.
