I will try to keep this as short as possible; please forgive the long post.
This semester, we were required to make an equal access path on a designed topography.
The workflow was like this:
- In AutoCAD, draw contours using polylines
- In AutoCAD, draw a path’s outline with vertices at ramp endings and landings
- In 3ds max, elevate the landing vertices and contours to specified elevations.
- In 3ds max, use the contours to create triangulated mesh solid for boolean
- In 3ds max, use path outline to create ‘bevel’ used to boolean with the solid mesh
- Render, and contour the solid boolean result.
This workflow was very problematic due to 3ds max instability/unreliability. I spent many dozens of hours failing.
I am wondering if something similar can be achieved in Rhino. The biggest question is how to set up the boolean components.
- The topographic mesh can be created with Delauney and converted to Polysurface.
- The path with a tapered ‘bevel’ is where I’m lost.
– How does one create the purest boolean path component given that the path outlines have varying elevations. Sweep/loft/offset/ribbon offset/GH?
– Can it be done as a single component, or would it have to be multiple booleaned together?
– How does one create the path taper?
– Can the boolean landscape take on the material id of the bevel operands?
If you have any ideas or thoughts about the above, would be greatly appreciated. This is very useful for landscape design.
