Hi all,
I have few points with known x and y coordinates. I can successfully use SurfaceDraper to extract z-value of those points. But it seems to get one z-value for points touch on one surface. If I have a point that can touch two surfaces, I cannot get two z values but any one only. How can I get two z-values?
Is there any other transformer to extract multiple z-value of a point on multiple surface?
Thanks
+50I've done this by using 2 SurfaceModellers, same drape feature, different surface features. In between I use a CoordinateExtractor to grab the z-coordinate and a 2DForcer to 'reset' it.
+17I think @redgeographics is on the right track, it all comes down to how you retrieve the z value, if you retrieve it into the same attribute it will be overwrite the previous value.
+50Yes, sorry, I forgot to mention that :) The 2 different z-values are stored in different attributes.
Another thought, create clone points of the number of surfaces overlapping at the point to collect different z values for the same location from multiple surfaces.
