How to Create a Multipatch Sphere via SDK

DHuantes — Mon, 03 May 2021 14:21:08 GMT

I'm using ArcGIS Pro version 2.7.2 and the 2.7 SDK.

I've created multi-patch features programmatically and I thought it would be simple to create one from a simple shape. Specifically a Sphere. I've looked high and low and haven't found an example or figured out how to do this yet. Via the Pro UI, I can add a Multipatch Feature Class and the Create options allows the interactive creation of a sphere but the MultiPatchBuilder.MakePatch is limited to esriPatchTypes... An help or examples would be greatly appreciated. Thank you!

Hello

Attached is code for a button that creates a multipatch sphere and adds it as a feature to a multipatch layer (rename the attached file to MultipatchSphere.cs). it uses the MultipatchBuilderEx builder object constructing patches of type TriangleStrip.

Let me know if you have any questions about the code.

As a result of your question, we have added additional constructors to the MultipatchBuilderEx object (and the related convenience methods) to support the creation of some basic 3d shapes. These will include cubes, tetrahedrons, diamonds, hexagons, cylinders, spheres, sphere frames and cones and will be available in the 2.9 ArcGIS Pro release..

Regards

Narelle

Hi,

I wanted to confirm that additional constructors have been added to the MultipatchBuilderEx object at ArcGIS Pro 2.9 to add basic 3d shapes such as cubes, cones, spheres, diamonds, cylinders etc.
