Vertical Polygons ArcGIS Pro

IvanoGasco — Fri, 24 Mar 2017 14:10:32 GMT

I'm creating vertical polygons with pyshp tranforming mz geological cross sections into xyz.

If polygons are exactly north-south or east-west directed they draw correctly

otherwise they draw badly.

In ArcScene all is fine.

Anyone had this problem before? It seems some sort of ArcGIS Pro bug.

Cheers

Can you attach a sample?

I think the triangulation method in ArcGIS Pro was replaced by a different one which can’t handle the true vertical polygons. In this case every second triangle has a different winding and that’s why the face culling removes them alternately. The true vertical polygons were always problematic and not fully supported—especially in arcpy and ArcSDE. I can’t provide you a solution, just a workaround: run a “Layer 3D To Feature Class” against your shapefile in ArcScene. It would result a multipatch feature class which rendered always correctly—even in ArcGIS Pro. If you can try to make triangulated or ring-based multipatch surfaces from your cross-section data.

Our devs took a look and we've got some ideas. Thanks for reporting!

In the meantime, Akos has the workaround - the Layer 3D to Feature Class tool.
