Create Tin Surface by Cropping

[Ed.McGriskin]

Hi all, 

I was wondering if anyone has any experience with the Tin Surface CreatebyCropping Function.

The specific stumbling block I have come across is the best way to deal with the database that is required to export the new cropped surface to as it has to be different from the current drawing. I don't actually need the cropped surface to be saved but need to be able to adjust elevations and extract the tin from it. The tin would then be used to generate a pregrade surface in the base drawing. Previously I had done this with non-destructive boundaries but I find the cropped surface to be more accurate. 

Thanks in advance.

Hi Ed,

I have posted a working code sample on TinSurface.CreateByCropping() in http://adndevblog.typepad.com/infrastructure/

Hope this helps.

Thanks,

Perfect. Does exactly what I need it to. 

One word of note for anyone using the code snippet, the surfaces you select need to exist in the drawing and can't be data shortcuts.
