I have both tried the tradititonal patch methord on my part but this method seems to be much more accurate because if you have very detailed contour lines, it gives you complete control where you dont have that option on the other method, thanks Sir!

Just in case someone as newbie as me in Grasshopper runs into the same problem, baking at delaunay mesh didn't do anything at first. If I put the cursor over the 'baked' command, I would get an 'invalid mesh' text. I saw on a forum you need to check for duplicate points, so you have to use the Cull Duplicates command between Explode and Delaunay, attaching them by the letter P on both sides. Thanks a lot, I'm really interested in GH now, this was only my first time.

Hey Frank! Great tutorial! I had a question reguarding the bounding box. I often recieve elevation data in the form of contours with site bundaries that are not rectilinear (most recently a property boundry that resembles the shape of a stingray). Is there any advice you could provide/ any recources you could suggest to help produce surfaces from those kinds of conditions? Thanks so much! Keep it up!

my problem starts at the explosion command it doesnt divide each contour but instead divides all with a large grid and because of that it ignores my contour line and just creates large polygonshaped surfaces with relations to the heights

Does this method work for a bounding box that is not a uniform polygon? The contours im attempting to use have a steep drop off, but are all comprised of closed curves. Im getting the null point error, but dont know if it is due to my bounding box being irregular even though it appears to be within all the contours

Workaround: I only had a contour lines for an irregular bounding box, since the property line of my site was irregular. I added simple straight line contours in the same general direction of the site's drop to 'finish out' the rest of a regular rectangular bounding box, and use this script. Later you can trim the surface to fit the irregular bounding box based on your site's shape.

Great video, thank you!! Do you know how could you do the same with a bounding box with more than 4 corners? If I add a 5th or 6th point so that the bounding box is not a rectangle shape, the point list will show "null" in every index of the points. Is there a workaround for creating a more complex shaped surface with this method?

@eh92745

I think I found a walkaround. Basically draw a rectangle below your contour lines and select it as part of your Delaunay input (pretend it to be part of your contour and it has to be bigger than your entire contour area apparently), you could probably imagine the result you get would be a mesh that almost look like using the rhino drape command and create something that drapes over your topo all the way to the plane you made, and this mesh is gonna be a rectangular shape with no issue going through the rest of the process to make a nurbs surface. I tested this method on three diffeerent set of topos, one with a flower shape, one even got missing areas inside the contour, it all worked nicely. One thing to note that I wouldn't use that same rectangle direclty as the bounding box input but shrink it a little bit to make sure it stays within the footprint of the Delaunay mesh you created, otherwise it might return null in the end.

I think 3d placed, because the height of the contours affect the height of the points which create the mesh.

Try just using a basic 'Divide Curve' component. The purpose of the 'exploding' the contours is just to turn the contour lines into a bunch of spot elevations - it doesn't matter how you get those spot elevations.

make sure that the bounding box you draw is within the contours - for the method to work all points in the divide srf need to successfully project on to the mesh and that can only happen if the bounding box has a smaller extents than the contours
