Create contour by Shape or by Selection?

[Costas]

Hello all.

i can create Contour Lines in a project just fine BUT I would like to create Contour Lines only in a small area from a project and i cannot seem to find a way to do that.

I tried to create a Polygon area and set the boundary type and then create the Contour Lines but the lines generated are from all the area covered by the project and not in the selected area.

Is there an easy solution to that (kind of generate by selection or something)? AND/OR is there any script available that can do just that? I'm not good at scripting so if there is a ready script available it would be much appreciated.

Thank you in advance for your help.

Boundaries are used only at export time, so what if you export the dem limited to your boundary and then re-import it on the same chunk?
I guess it would work as you want.

Thank you for your answer JMR.

This worked nicely.

It would be great if we didn't have to do this (export/import) and had the option to do it "by selection" but until then it is a very good solution. Thank you again.

Best regards,
Costas.
