Hardscape and roadway

[Siddharth]

Hello,

What is the best workflow for creating hardscape on slope (uneven site)?

How to attach the roadway to the topography?

It depends on your intention and what you are starting with and what your final intention is.

 

If you are starting with an ungraded site in your site model and proposing modification that will change that grading, using hardscapes, slabs, and walls with site modifiers to shape the site is pretty effective.  The bonus here is you end up with a graded site model that can show the proposed contours and surface.  It takes a little effort to learn the tools for creating sloped hardscapes and retaining walls, but it is very worthwhile in my opinion.

 

If you are starting with a graded site that already has the surfaces developed where the hardscapes or roads will exist, you can use hardscapes in the texture bed mode applied to the site model to quickly depict them on the site model surface as well, basically projecting a 2D representation to a 3D surface while retaining the ability to reshape or retexture the proposed hardscape non-destructively.

 

There are other processes you can use as well, but those are the two big ones I use.  The attached image demonstrates both techniques used on an existing site model where the road and driveway were already represented on the site model by drone survey.  The site modifiers indicated were used to clean up the site model where the drone survey produced sloppy results.
