Adding custom floor-plan dynamically, receiving "Duplicate point 0:0" error

[guy16510]

I was working on adding custom polygons, and using those to drive the creation of the floorplan. I have a series of polygons, and wanted to have those rendered in this application without the need for using the UI editior.

Playing with this a bit, and formatting the design.Blueprint3d file, I get the error:
Warning, unable to triangulate polygon!
three.min.js:667 Duplicate point 0:0

Does anyone know how to resolve this issue?

Thank you

I ended up cleaning up how I was drawing the polygons.. However loading up more than 100+ walls/corners/etc causes errors with threejs.
