Problem Using CAD topo surveys

Thanks Virag

When I try and import via Feature Surface a box opens up named Load Contours which shows the contours in the 'Original Data' area but nothing in the 'Extracted Data' area even after trying various filter selections and 'Set from Sample' selection.

All the data is there, but the software doesn't seem to be able to recognise it...?

Any ideas?

All sorted - OS contour data had been provided as a Block - needed to explode to create polylines!

Hi timetomaketracks,

I was just drafting a reply suggesting this solution.
I'm happy that you managed to resolve the issue.

Cheers,
