Why wont underlays show?

[Martin P]

I am sure it is a very simple explanation that has been covered somewhere else, but I very often go to underlay a view and very little or none of it appears as underlay? why is that, and how do I work round it?

cheers :)

1. Check you crop boundry settings. You may need to increase the size of the outer boundry.
2. Set your view display to wire frame.
3. is the underlay an autocad drawing or a portion of the model? If it is a portion of the model you may need to change your view range settings.

hopefully this will correct the problem.

If your view range is set so that the underlay you want is allready included you wont see it.

For example, I have a second story of a building and I set the view range bot. to the lower level so I can see a roof below. then i won't be able to se the lower level as an underlay, the floor will be hiding it.
