I have 2ft contour lines from a DWG file that I brought into microstation (V8 2004/Geopak Roads). When I use extract graphics (contours), in some areas the TIN doesn't follow the contours very well. Is there something that I could do to make this look cleaner? For example: the purple circle is a high spot, and it connects to the adjacent contours of the same elevation. The green and blue circles just cut corners. I have little experience working with TINs and maybe I am trying to accomplish something that can't be done.
I have moved this discussion to the OpenRoad forum since the "extract graphics" tool is a Civil tool. This will allow you to get better assistance with this issue.
Have you used the Generate Inferred Breaklines (Surface→Utilities→Generate Inferred Breaklines) before drawing the surface?
This should clean up the model a bit. Please see this guide: https://envisioncad.com/import-contours-from-graphics/

Try adjusting the Stroking parameter to the right of the Contours selection. It should bring up another small dialog. Depending on the tolerance and min distance, you should get a different result. If that doesn't work, as Thomas mentions, try extracting as breaklines instead. You can try creating the tin in a similar fashion, however take those problematic contours out at first and add those high points later. Use "File Open: Append" rather than "create" to add them as a breakline feature type.
Thanks for the reply, I think my version of microstation/geopak might be a bit outdated for the features you mentioned.I saw Road listed in the application drop down, but i guess it is not the same version you are referring to. The images I attached are what I see when I click on applications, then when I click on Geopak road->About.
Thanks for the reply. I do apologize, I should have been a little more clear in my original post. The contours I received have more vertices than I could ever count. I have tried different stroking parameters, but that has little effect since the triangles hit every single vertex. Extracting the graphics as contours seemed to work better than as break lines.
Are you suggesting that I extract as contours, and append with break lines (breaks)?
