Hi all.
I have been working with Inroads SS2 to create a surface (.dtm) file and was looking to create a terrain model from it in Inroads SS4. My surface consists of proposed roadway features (edge of pavement, edge or shoulder, centerline) of the main line as well as existing features for side roads. I'm attempting to build intersections using proposed curves to tie these features together.
I have used Inroads SS4 enough to know that geometry features can be have profiles displayed and adjusted easily. I want to display all of these intersection curves vertically so I can smooth them in between my two crossing features. I know a way to do this with Inroads SS2; however, it would be tedious to create baselines and profiles for all of these features. (Also, I want more experience with SS4.)
Anyway, I used the Terrain Model -> Create from File command and brought in my .dtm that was created with Inroads SS2. This created a bunch of features in the void spaces and other areas that were not originally there. It did capture my features though they are now all on the Default level. Then I tried to use the General Geometry -> Create Civil Rule Feature on the intersection curves and it says the tool is not valid. This basically left me with a "terrain model" I don't know how to manipulate.
I understand how to create geometry within dgn files using Inroads SS4, build profiles, and create corridors; but now am simply trying to take features from a dtm and use them with the new software. Is this a practical application? What exactly is a terrain model and how is it manipulated? I thought they were simply the new name for surfaces (.dtms) but I'm starting to think its more complex than that. I feel like these are just basic questions and my knowledge of the fundamentals is lacking, but I don't know anyone who can explain it to me which is why I am here.
Any help would be appreciated. I'm just trying to learn about SS4 and how a terrain model is built and worked in.
Thanks for reading
