I have just started to design a coaster based on the Raging Raven boss from Metal Gear Solid 4 game. It is going to be a full circuit launched Inverted Impulse Coaster which will launch to 63 mph, I am not going to use any tools apart from the smoothing tool built into Nolimits and the autoflange tool. Below are a few screenshots of what I have done so far.
In the screenshot below you can see a smooth LIM Trim section which is barely noticeable when you ride the coaster in the simulator
In this screenshot you can see the launch and the twisted top hat element which I have designed to have a bit of hangtime at the top
Below is a screenshot looking down towards the station over what I have done so far
I will post more as I progress and hopefully a version 1 will be on the exchange soon so people can review it and give me some pointers for a version 2.
