Level Dimensions

[Anonymous]

I would like to show spot elevations of ceiling slabs on my RCP's. When I use the level dimensioning tool it gives me a dimension to the top of the ceiling slab (i.e. 9'-1"). The ceiling elevation should be 9'-0". This slab is also linked in sections correctly. It seems that I need to change a level dimension setting somewhere that dimensions to the bottom of the slab instead of the top? Any suggestions would be great?

Thanks,

Brian

You need to load the library part into your project.
