KMZ falls in wrong place

Postby RJOHNSTONPSM » Tue Sep 13, 2022 8:13 pm

I copied line work out of a 2015 C3D drawing into Carlson Survey 2021, did a centerline alignment and the coords were the same as C3D drawing. Both drawings are in Texas north central, when I made a KMZ with Carlson it put it in Nebraska. Has anyone else experienced this issue? last time I brought it up to Carlson they said they would look into it , I never heard anything. If you go from Carlson to C3D it woks fine just not the other way around any ideas?

First thing that pops into my mind is to check the datum / projection parameters Carlson is using. I use Carlson on Intellicad so maybe this is different but take a look at Settings | Drawing Setup | Define Projection then select the Texas projection and hit Edit. Verify the parameters are correct. There is a Test button you can use to convert a known trial point to determine if the transformation is working as expected.

I had this happen once. I ended up copy and pasting the lines into a new file, and then they exported to Google Earth fine.
