Alright, this may be drifting off the original topic, so let me know if I need to move it.
I wasn't really familiar with transit-enabled lots, but now that you mention them I've done a bit of reading, and have a different question. It looks like I can make growable lots transit enabled. At least, when I use the TE editor in SC4Tool, I can open up growable lots and add a network/transit switches. Maybe there will be some problem further down the line, but for now I have a different issue. Growable lots that I've created in PIM-X show up with a red marker in the TE editor (picture attached). This is green for other growable lots. In addition, I am not able to add transit switches to these lots. Does anyone know what this means?
EDIT: Ok, it looks like the red dot and the failure to add transit switches is a result of the separate lot and desc files. I'm able to add transit switches in every case where the lot file contains both the lot and building, and I'm not able to do it wherever the lot file is just the lot. So my new, new question is, is there a way to subsume the desc file I created with PIM-X into the associated lot file?
Sorry, this has drifted into a SC4Tool question.
