ArcGISPro MultiPatch Stretching

nicholascarrington — Fri, 25 Sep 2015 13:53:02 GMT

Once in a while when converting multi-patch data to a new coordinate system I get a stretched effect. I think the z height value is dropped or ignored. See below:

original model Project tool stretched result

Anyone else encountered this? If so, do you know what caused the error? how did you fix it?

Thanks again,

Before reprojecting the data, were the Z values in feet or meters?

I think it would be in the wrong units. But when I re-project it's not changing the z value, I don't see options to change the Z scale. So I go from feet to meters in the re-project. X and Y changes not the Z I'm assuming.

Hmmm, is there a tool that converts the z values. I'm new to GIS.

Gabriel, thanks again for your response.

To my knowledge, ArcGIS does not project/transform Z values, which is why I asked. You can usually find a way to do it manually though. I would start with trying the Adjust 3D Z tool using the From Units and To Units parameters. Keep in mind that this tool modifies the input data (I.e., it does not produce a new copy of the data) so be sure to create a backup copy of your data before running the tool. Here is the help doc: Adjust 3D Z—Data Management toolbox | ArcGIS for Desktop
