Layer Eleveation Problems

[MikeN]

The layers that I'm creating manually through the layer command window or via the model setup command, are not retaining the elevation data that I'm assigning to them. Whenever I switch from 2D to 3D views, the elevation data reverts to '0' quite frequently.

Anyone else have this problem? Any sollutions?

i'm not sure I understand what you mean. Are you saying that the layer setup (Z and delta Z) keeps changing, or are you talking about the information on the layer.

Z data keeps changing....

[Jonathan Pickup]

where does the Z data keep changing? can you be a bit more specific.

What dialog/palette are you looking at?

describe what you are doing before the Z data changes..

Are you saying that when you have LAYER> SHOW OTHERS selected, and you go to a 3d view, the layers don't show you their correct z heights relative to each other? If so, then I think you have missed an important point about 3d modeling in VW's: When there is more than one layer invloved, with various z values assigned to various layers, there are only two ways to view the model: first, you can use a LAYER LINK, and second you can use a VIEWPORT.

the Z data changes in the Layers Setup dialogue box. i set the Z data in the layer before i start drawing, i'll put together a plan or two, switch to a 3D view and all the plan data that i'd set at particular Z co-ordinates has reverted to 0 and the all the layers are at the same elevation. there is no particular instnace which seems to trigger this other than switching from 2D to 3D.
