i"m new to revit (using 9.1). how can i get everything below the toposurface (grade) to be invisible in elevation and/or 3d views, for presentation purposes?

I've been doing this with masking regions (under the Drafting section of the design bar). This seems to be the easiest way, but it will not work for 3d views. k

one option would be to duplicate your 3d/elevation view, rename it to something like 'above topo' or something along those lines and then just hide everything that you dont want to see in that view. this way you'll still have a regular view that you can manipulate as you see fit, but you can revert to this other view for your presentation purposes and everything you want to be hidden should stay hidden just my .02

masking region works well for elevation views. i'm still not sure how to do it in 3-d views. nightryder suggests hiding things below grade, but part of my foundation wall is above grade and the garde is very uneven so i couldn't even make a clean break in the foundation wall to hide it.

maybe, is it possible in revit to create a cropping plane that would "crop" everything below the plane? or is the only solution to model the topo surface so that in 3d views i would see dirt below grade ?

"maybe, is it possible in revit to create a cropping plane that would "crop" everything below the plane? or is the only solution to model the topo surface so that in 3d views i would see dirt below grade ?" yes...you can use a crop region to adjust what you see in the view...or you can use a section box and actually crop away parts of your model. depending on how non-uniform your topo is this may or may not work for you...you can activate the section box within 'view properties'...scroll down to 'extents' section and check the 'section box' box. from there you can select the section box and drag the arrows around to mold what you want to crop...hope that made sense.

yes i understand what your saying nightryder, but the box is square and my grade is uneven.

" yes i understand what your saying nightryder, but the box is square and my grade is uneven. " yeah i figured that would be an issue...is it just foundations that you see under the topo? you could always try and create in-place void families and cut the geometry that's under the topo...that way you'll still see what you want to see above the topo...

i'm a beginner so i'm not sure what in place void families are, but i'll look it up and see if it works

see the attached image...this is a very basic idea of what im talking about...you essentially create an 'in place component/family' and choose void extrusion or sweep...then you use the 'cut geometry' tool to cut the solid (in this picture the foundation and the wall) using the void...the final product is just an empty area where the void was...it's a pretty simple concept and there should be some tutorials around

so if i understand you correctly, you are basically getting rid of parts of the foundation. does it go away for good or can you turn it on and off as needed?
