Hi, I have an XYZ file with 1 million points at regular 1m horizontal intervals.

 

 

I want to convert this to contours, however when I tried ContourGenerator and SurfaceModeller transformers, all I got was a square polygon showing the extent of the XYZ points.

 

 

Does anyone know what I'm doing wrong or if I should be using a different transformer?

 

 

Thanks,

Have you used the pointcloudcoercer to decompose the XYZ into points?

According to the documentation, the Points/Lines input port of the SurfaceModeller should accept point clouds, so I think it must be a different issue. In fact, it worked for me when I just tried it (see screenshot below).

 

 

So... maybe try reading the point cloud into the Data Inspector to make sure the reading part is correct. Then, well the only parameters I can see that would make a difference are Surface Tolerance and Output Contours, so check those.

 

 

If neither of those work, then please do contact our support team for assistance (safe.com/support)
