Today I had a question from one of our users as to how I could reduce the size of a surface model created from contours that had been provided by the engineer - the problem was they were having difficulties outputting the model to GCS900 because the model was too dense - primarily because the provided contours were chorded at eg 1' Intervals - How do you tackle that?

Project Cleanup.

In the project cleanup command I checked "Filter Line Vertices", left "Include CAD splines" unchecked and used 0.005 for my circle filtering radius. Please reference my attached image "BC HCE v4.11_Project Cleanup Magic" for all of the settings used. 

After running project cleanup this reduced the TIN from 203102 vertices to 57282 vertices removing a total of 145820 vertices. This allowed me to export out the design for the machine and the customer was overwhelmingly please. 

Amazing work BC HCE! I could not live without you!

Great work Layne

I also had something similar this week - a customer gave me a set of plans in PDF form that we vectorized, the contours were really jagged and zig zagged - we used the same command - but with a coarse setting for the circle filter radius of 0.2' and it also worked really well to eliminate all of the zig zags without damaging the contour paths at all.

Good to hear that Project Cleanup helps clean up all those poor PDF Vectors or super dense CAD files with little change to the resulting surface - got to think of those downstream users  / consumers of the data on site - small changes but huge savings for the field users.
