AutoCad 2008 - 3dHidden visual style not displaying properly

[the_mini_guy]

Good Afternoon,
I am wondering if anyone else has run into this;
I am trying to apply the 3dHidden visual style (in AutoCad 2008), but it doesn’t seem to take effect, even after invoking the Hide command.
I have checked in the visual styles editor and obscured lines are set to not visible, I have changed the VSHIDEPRECISION to 1 (more precise) but I am still seeing lines that should be hidden.
Any help would be appreciated,
Thanks
TMG

Are you working with solids or faces?

Here is an excerpt from the help file.

"HIDE considers the following to be opaque surfaces that hide objects: circles, solids, traces, text, regions, wide polyline segments, 3D faces, polygon meshes, and the extruded edges of objects with nonzero thickness."

Lines won't be hidden if there is nothing in front of them to hide them. If you only have lines in your drawing you will have to create solids or 3d faces to be able to hide the lines.

I have found the issue is a setting in autocad, the visual styles manager does not retain the settings for obscured line display once the drawing is closed; so I had to go back into the the visual styles manager and set obscured lines to 'off' before doing any plotting.
thanks,
