Problem with Dataset Explorer

AecoSIM Building Designer v8i (Select Series 4) - Problem with Dataset Explorer

I'm using extractions to get sections out of quite a complicated model.

How can I place pattern on its own level ? I'd like to have the ability to switch off patterning in some instances without switching off the linework.

And also a major problem : I want some parts shaded in section.

I can get this to work, but the shading is offset from the linework by about 2mm which is obviously useless to me.

Is this a bug ? Or a setting ?
