Wooden Support Engine

I've seen these in quite a few coasters. I'm running NL 1.6 (1.71 kills my FPS), and I have the standard "stair step" style supports. However, on some coasters, I've noticed where it's more of a bow. Heres an example:

My supports always look like this:


What tool do I use to create them to look like this:


Thanks.

Use the wood magic support gen. Its one of the first two slop structures.

Hint: Put your auto-support mode on preview Final Quality, and then try out the different build-styles [:)] You can see what the difference is between all 3 styles. The one you'd want to build is the slope structure. [:)]

They're just a different design of supports, under supports in the auto support generator it should say build style, click steeple as opposed to any of the others to achieve these supports.
