Z value referencing block

[Al_H_C]

Hi,

 

Does anybody know a way of creating a block attribute that will reference the z value of a separate 3d model (topographical survey) at a given point?

 

I know the z value of the block itself can be listed as a simple block attribute but I need the reference to check for the z value of an unlinked model which will be inserted/ x-reffed beneath the block.

 

Any ideas?

 

Thanks

Create a block that consists only of a point, with an attribute that shows the Z value of the point.

The block inserted in a drawing, even if the input point is selected on an X-ref will show the height !

Hi Steven,

 

The block would need to have multiple points (corners of a building) and would not necessarily snap directly onto an object on the topo. To be honest I'm not sure it's something that's really possible having though about it.

Might you be able to use a FIELD instead?
