This is just a brainstorming post, in hope some one might have an idea to guide me on this!
I want to generate line work from an aerial image. I feel like it can be done, but every time I try, Civil 3D crashes on me.
My intended workflow is to:
- Read in the image
- Get the pixel colors
- Create dynamo points with the same array as the pixels
- Create a new list of the point and respective colors
- Create surfaces of the points within a close color range
- Get the topology edges
Whenever I have an excessive number of points it crashes though! But I need a high number of points to accurately depict different terrain colors and features.
Any thoughts are greatly appreciated. Thanks
