Wanting to build an industrial catwalk but don't know where to start

Hello! This is my first time posting on the forums, and I had a question that I couldn’t find on youtube, or on Google. I want to make an industrial catwalk, something similar to this picture http://www.smartspacemezz.com/wp-content/uploads/2016/07/crossover-platform-catwalk.jpg .

I really want to learn how to make one since I plan on making a map for GMOD, then coverting the map to hammer so it will work on GMOD. I have tried using images from google of a transparent industrial catwalk, but it hasn’t worked since you couldn’t see the ground underneath you, only the parts of the block. If you have any suggestions, or some guidance I would be happy to know whenever you can. Hope you have a good day, and thanks for reading this thus far.


You’ll probably want to get a 3D modeling program like Blender (free) or Maya (paid) and start to learn the basics of modeling and texturing. There are lots of free tutorials and guides available to help you get started.

Good luck!
