Combining 2 cut area surfaces

[sbrasher2010]

Ok, so I have an oddly shapped "cut" area with various elevations that I want to create as a surface so that I can compare the volume with existing survey data. I've been able to get the basic "cut" template in 2 seperate surfaces, but now I want to combine them into 1 surface. When I paste one surface into another, the surfaces go haywire. I have attached a plan and cross section view of what the 2 surfaces (cuts) look like in relation to each other. Does anyone know how I could combine them into one surface and "trim" off the inside grading that overlaps..?

Thanks in advance for your help!

Your section view suggests both cut-outs daylight to elevation 5. If so, you could make a flat surface at elevation 5. Paste the smaller cut-out into that surface and then paste the larger.

I'd probably find the intersection of the surfaces ( Mindistbetweensurfaces?) and use this to create two boundaries around the surfaces, then create a new surface into which the other two are pasted.

You guys rock. Thank you so much for the replies. Those are both REALLY good suggestions. I went ahead and tried the "minimumdistbetweensurfaces" routine because I've never used it before. After a few trial and errors, I was able to create a polyline at the intersection of the 2 surfaces and then use that polyline to create breaklines, boundaries, remove overlapping triangles and then paste the 2 surfaces together. It looks perfect. Whew! Thanks again 🙂
