Does anyone use Surfcam V5.2 (or other version) with solids to do 2 axis milling?

I've been using Spaceclaim to make solids and I'd like to export to something, then import to surfcam, but all I'm getting is wire frames and selecting pockets or contours is difficult.

I'm thinking that having the depths to choose from might be quicker with the solid.

Any input welcome.

Thanks
Nick
