NoLimits Questions

I have two questions about NoLimits. The first has to do with any version of the game. Is there a way to find the angle of descent while building a roller coaster or when complete?

My second question regards NoLimits v1.6. On this version can you make underground tunnels with you track?

Thanks.

1st question, not in the program itself. you can, however, take whatever segment it is (make it a small one with exactly the angle you're trying to find, no other) and make a new track with it. then load it into the AHG and it'll tell you starting/ending slopes and all that.

2nd question, again, not with the program itself. the only way to make underground tunnels is to replace that section of terrain with a 3d object edited to look like it. there are several tracks out that show this method.
