Getting GM to use the elevation values in a dwg file

I want to run a view shed that takes account of building heights. I have imported a dwg file that has surveyed building heights in it. However when I've loaded it, the elevation values in the area covered by the dwg file don't change - they're still the values displayed by GM before loading the dwg file.

How can I get GM to recognise the elevation values from the dwg file so that they will be taken account in view sheds across the area?

Thanks

    On the right hand side of the view shed dialog is a section where you can specify to use vector layers as obstructions. You would use that and check to use your DWG layer so they will be used on top of the terrain layers.

    Let me know if I can be of further assistance.

    Thanks,
