The question today, came from my Civil 3D bro up in Seattle, Bryan.
We are generating some graphics and when I switch my view to ‘realistic’, it shows the triangle edges of the isolines. I can turn them off in the view toolbar, but when I produce a camera angle of the model and switch it to ‘realistic’ I do not know how to turn off the isolines. I do know there is a dialog box like a toolpallete that I can turn it off, but I do not know where that is, can you help?
To get rid of isolines in realistic view:
1. Crack open the Visual Styles Manager (VISUALSTYLES at the command line).
2. Click the “swatch” for Realistic at the top of the palette.
3. [OPTIONAL] Right-click the swatch and select Copy. « [Doing this you can keep the original Realistic style and make your own called “Realistic – No Isolines,” for example.
4. Towards the bottom there is a listing for Edge Settings.
5. You’ll see an option for Showing Isolines.

6. Set the isolines to none.
7. Boom, yer done!
