Steel Supports on Wooden Coaster

Hi.Im new to this game. Is there any way to quickly erase the wooden supports or not just put them on the wooden coaster and just have the handrails and catwalks? Also, I need help building the steel supports like the coaster Hades or Voyage has. Can anyone help?

Open the auto supporter, uncheck catwalks and handrails on both sides. Support with whatever pattern you want.

Then after that click edit, select all, double click on a support and set L or H beam, and set the steel color (silver or whatever) in individual color.

Then, go back to the auto supporter, uncheck clear previous structure, enable supports, wide supports, collision detection, and recheck handrails and catwalks, and then generate supports again. Set the wood color for these with the normal support colors in the coaster settings menu. That should be it.

Thanks Freddie. That did it.
