I'm New to NAM and RHW + How to fix this?

[Mayor Isaac 1]

Hello all,

I'm very new to NAM and RHW... And I have to say, I'm a little overwhelmed. I see a lot of people making huge interchanges an expressways and I just can't figure it out. Also, there are some MIS ramp curves and parts to interchanges that look weird and not right. How do I fix those?

Install NAM via SC4pac instead of installing it manually, which can easily cause problems, especially for those without basic computer skills.
