Hi, sorry for taking a few weeks to get back to you. 3D content is possible to create in the Lite version of PolyOne3, but much easier using custom properties in the Pro/full version.

If you only need a few levels of height (or in an imaginary Z-coordinate), you can get by like this:

1. Separate each Z-coordinate into its own layer, and include that Z-coordinate as a prefix or suffix in the layer name. You should probably use some character to separate it so you don't have any processing mishaps.
2. When processing your exported JSON file in your engine, assuming you're doing that, use the suffix/prefix in the layer name to determine which Z-coordinate you give the geometry in that layer.
3. In processing, you could also make it so that triangles where two vertices are at the same position create walls.

A couple of gotchas:

• PolyOne3 doesn't currently provide a way to rearrange the exported file data so that editor Y-coordinates go the vertsX or vice versa.
• If you need a .obj export or similar, PolyOne3 doesn't have a feature for that yet.

Thanks for your interest in PolyOne3!
