Hey, I’m making a quick little thread here just as a suggestion for anyone trying to get into mapping.
Before the map is even being worked in Hammer, it’s often a good idea to start out with a design with pen and paper. I often suck at it and I personally end up being weird when drawing, so I’ve decided to dive into the realm of CAD.
Here’s QCAD, a free program that I use. (It’s got trial plugins that I’ve disabled since installation, but it’s freely expandable otherwise!)
I’m using it to design the insides of buildings, currently:
I was able to transfer my ideas from QCAD to Hammer quite easily, and it’s quite fun. Perhaps you can give it a try!
