So I'm ashamed to admit that although I've been playing TS3 for years, I only recently discovered the blueprint feature. It seemed like a pretty neat idea, but the blueprints provided in game are few and there's not much variety. So I took a look around the site for custom ones, but didn't see any.
Does anyone make custom blueprints? Is it too hard?
I'd even be willing to make some myself if I knew how. It would be nice to have a "place-holder" set so I can put together a house and make sure there's room for all my furniture in one go, then just switch out the stand-ins for the furniture I want.

velocitygrass has been working on a blueprint maker to turn any room into a blueprint. You can test it here. Once she gets it working and uploads it, I assume people will start to share custom blueprints. It's an awesome project. You ought to check it!

I'm pretty sure those are new... Nothing to be ashamed of. I noticed them after I downloaded one of the last three EP's I think... It could have even been UL.

It's 2017 and I still can't find CC Blueprints downloads.

This seems to still be an issue and I've got a few to work on that will be CC free with the blueprint maker tool as I couldn't find any myself and ended up downloading the tool to start making my own blueprints.I might have a few options already available to be shared if they're CC free ones.
