A large circular base in the middle with the middle area having walls 1&1/2 boxes high with 2 tunnels through the side of it out to the rest of the map. At the top there is one box thick of boxes flat, and another box long of upward ramps(both all along the circular area). Then there is a downward ramp of boxes to the bottom of foundry, with gaps allowing for the tunnels into the middle. Then there is a circle of bridges about a box higher then the higher area and is directly above the pit in the middle. The pit will be roofed with shield doors. I can't think of how to do the rest of the map, and I am not that good at merging objects...
What? Please don't do text walls. They are very annoying and it hurts my eyes to read. Please explain in more detail and use paragraphing and correct grammar.
What are you talking about Mutual? It's one freaking paragraph. He has good grammar too, so stop complaining. He is using paragraphing, because it's only one paragraph. Now, Orlando. If you get an idea for a map and you're not sure if it will be good, use Fritzster's Foundry Components on Google Sketchup to design it first. That's what a lot of people use. You can find it by searching sketch-up components.
This is a great forge tool, but personally I could never get it to work right. You could always go old school and Draw it out. That always works, and you can upload the images to the computer to show us what you're talking about to.
