I haven’t implemented any of the geometry types for the external stuff, so unfortunately I don’t think you’ll get very far 😕

On a separate note…this might help with that `ProtoCore.DSASM.StackValue` output.

I am working on a script that connects to online parcel data via an API, grabs the coordinates, converts them to points within my coordinate system and draws the parcel on the layer of my choice. Super simple, but I do not typically work with dictionaries all that often, so what am I missing here with this error? Normally I can get through it, but this one is destroying my soul today. Thanks in adva…
