3d surface modeling

3d surface modeling

3d surface modeling

how do you convert 2d contours into a 3d surface model? can it be rendered by using visualization tools?

my goal is basically turn a 2d site plan drawing into a 3d model with materials attached in the drawing like grass,trees,brick walls,etc. for a perspective view presentation drawing, maybe a fly-by simulation if I have time.


RE: 3d surface modeling

What package are you running first off? Geopak, Inroads....etc.
Let me know.

RE: 3d surface modeling

Just running off a Microstation V8. We also got Eagle Point, but I want to stay away from that for now, but if it needs be, I can use it.

RE: 3d surface modeling

First, create a new dgn with a 3d seed file.
Next, reference the 2d file to the 3d file.
Copy the contours into the 3d file.
Change the elements to thier corresponding elevation.
Make sure that your elements are polylines.
Go to Tools>Surface Modeling>Create Surfaces.
Here you can take and interpolate between sections, and all kinds of cool tools you can use.

RE: 3d surface modeling

thanks namdac! appreciate it.

RE: 3d surface modeling

If you have any other question feel free to ask. I have also created some procedures that would be benificial if you are just starting in 3D.
