Sloped Surfaces

Post by Geomatic » Tue Jul 26, 2011 6:33 am

I am trying to design a theoretical golf hole with tee box, fairway, and a multilevel green. I have imported the topographic data and created a Ground Surface and a Tin. My question is: How do I create and entirely new surface with sloped surfaces? I have already researched Autosite Design for pads and Autoroute for roads but pads are flat and roads linear and evenly proportioned unlike a landscaped golf surface. Any help in creating this type of surface would be appreciated.

That should be easy.
This is brief. Expect you can expand on this.
Design your layout in Cad.
Draw 3D polylines for your tees, fairway layout etc, setting them at the design elevation(s).
Join pads/ tees with 3D polylines as required.

Then model the 3D polylines and create a design surface.

Volumes can be extracted from the 2 surfaces.
Some allowance for batters (not sure what you call the line between design and natural surface ran back at predetermined grade)

Pads can be any shape - just create a 3D polyline and select that.
You could create multiple pads if needed.
Thinking of this I'd probably just design it 'on the fly' so to speak as outlined above.

You could also put design points and give them your desired elevations and join them with 3D polylines to create your overall golf course.

I'd contour the existing surface and use that in my design layout too.

Hope that helps.
