Site Hosted Elements

Does anyone know a way that I can keep my topo hosted elements (trees, rocks, whatnot) from falling off when I update the surface? Our topo is generated from a linked CAD file, and the only way to update the surface I have found is to delete all the points and re-create from the updated linked file. But when I do this, all the families hosted on the site fall to sea level. All the pads I'm using for hardscape stay in place, so I'm hosting as many elements there as possible, but that's not always an option. Grouping and worksets have failed me, I even tried paste at same point to no avail. Any ideas?

 

For what it's worth, I do know that ideally we should be using Civil3D to link in our surfaces and that the topo tools aren't really actively supported. Workarounds are appreciated.

I am curious about your workflow. You say that you delete and recreate the Toposurface from the updated CAD Link and you DO NOT loose the Building Pads. How do you manage that trick?

what about :

  • Select all entities 
  • Pick New Host - click to Toposurface
  • and turn Offset (from Properties -Level - Offset) to 0.00

Lol sorry, to clarify:

 

1. Edit Topo Surface

2. Delete all existing points

3. Create from import instance - select instance - select layers - create

4. Save Surface

 

So somehow the pads think it's still the same surface, but the families hosted to it do not.

That's pretty much the current workflow - once the surface is updated, select all "fallen" elements and re-host to the surface. The downside is that this site is 10+ large buildings with a LOT of site hosted elements to re-host... so this process is taking more and more time.

Why are you needing to continually revise the topography?  Are the changes affecting the entire surface or just portions at a time? 

 

What about a workflow that would use Split Surfaces to separate the portions of the Toposurface that are not being affected? And/or a workflow that Phases earthwork -- maybe using Graded Region Copies?

The site is under development, so we are editing the portions around each building as they are designed/finalized. I did think of trying to use split surfaces but couldn't figure out how to make sure the edges of each surface keep working together as desired. I also thought of using floors for hardscape instead of pads, and adding pieces of topo for the areas that actually need it, but again - is it possible to make the topo surface stitch neatly to the edge of the floor without manually placing points carefully along each edge?

 

Edited to add: forgot to respond to the graded regions comment, to say that I don't know enough about them to have considered that. It seems like it would probably suffer from the same challenges, but maybe not?

Maybe I don't understand you well , but I said to select all the objects (I made test only for trees) and then Pick New Host for the whole bunch    not one by one (but the whole selection) , pick the Toposurface and the set Offset to 0.00. 

Maybe it looks a little weird , but for me , at least, it works...

Oh no you're absolutely right, that more or less works, and is what I have been doing. :zwinkerndes_Gesicht: I was just hoping there was a way around finding and selecting all my errant objects!

I found a Revit add-in called "Topo Align" which will cause topo to follow a floor (or whatever) that seems to  work so far, so I'm going to try the solution of breaking up my surfaces - should help a lot assuming all goes well, thanks for the advice!
