  • if there is more than one floor detected / configured, the export will also include a hidden layer that has all floors (identical to the old export)
• adds configurable projection axis functionality
  • useful for generating vertical side views
  • configurable with argument, the default axis is z
  • screenshot of zigi's Tellus Terminus, part of Alkaline https://imgur.com/a/HkLmmfb

Whoa! These seem like great enhancements! Give me some time to review the changes?

Sure thing, take your time. Python is not my main language, but I spent some time to (hopefully) code it right. I like this tool so much, it really brings a certain beauty in every map. Excellent work. I've had fun extending it

I just pushed a new commit. Sorry if this complicates the review. I added the functionality to control the slicing-axis. This is an essential part for this feature, as you can see in the next screenshot. But I had to rename arguments and variables accordingly (mainly floor -> slice)

start map of qbj2 - Ears to the Heavens by Makkon, projected and sliced along the y axis, with half of the slices hidden

No sweat. I'll wait until you are done making changes before I start my review.

Also can you provide usage examples?

E.g. foo -d ./out -v
