Spot elevation & RPC view

[Nic M.]

When I'm in a RPC view the "spot elevation" command is greyed out.
Any reason why?

just a guess...

the spot elevation tool is build to read elevations looking down, so it can 'see' the levels below and determine elevation. RCP is cut looking up, so the 'elevation' data isn't there as it would be in a plan cut looking down. make sense?

Makes sense, but it would be nice to use the spot elev. to note the bottom edge of a wall acting as a soffit....

Interstingly enough, if you underlay a Level Above into a floor plan and then use the linework tool to show 'Overhead' items, then turn off the underlay, then use the elevation tag, they will display the correct elevations of the overhead items. You could use this trick to show your overhead soffit line elevations. Attached is a Level 1 Floor Plan view....

Thanks Scott, thats indeed a valid explanation
I guess I could "work arround" it using the cieling tag

Maybe something for the wish list

Another possible explanation is that this is a bug and RCP should be able to host spot elevation.

BTW - RCP is not trully looking up. It orients everything while still looking down but when doing visibility/hlr comparisons it considers items with lower elevation visible and hiding elements with higher elevations. Just trying to be precise ;-) I know what you mean.

Well, I GUESS I'll have to agree with Leonid's explaination! :) Something tells me he might know what he's talking about.Thanks, too, for the explanation of RCP views. I always thought RCP's in Revit truly 'looked up' from the cut plane. Probably why I have a hard time with view range in RCP's.....:Oops:
