Hi, has there been a change from Revit 2020 to 2023 in relation to topography and building pads? I've moved from 2020 to 2023 and now when I add a building pad it cuts my existing topography instead of my new construction topography. Nothing else has changed. I can't get a new building pad to cut anything but my existing topography.
Thanks,
Stephen

No, nothing has changed. Create a Graded Region Copy from the Existing Toposurface and place your Building Pad on that one. Make sure you are in the correct Phase and set your Phase Filter to Show Complete.
Thanks, I have a new topography that is quite altered compared to the existing one so going back to a graded region copy (which I did in the first place but I'm not sure it worked properly) is not an option. Too many months down the track for that. I don't understand why this is all of a sudden happening. I've been using building pads all over the site for months for various things and haven't had an issue till moving to 2023.
Sorry, not sure what you mean? I'm creating the building pads in views set to new construction and the existing topography isn't even showing as it's below the new topography but the pad is acting on the existing topography instead of the new one.

The existing Building Pad should not even be in the View if you are using Graded Region Copies AND the View Phase Filter is set to SHOW COMPLETE.
....if it's a bona fide Graded Region Copy, then the source Toposurface is Demo'd in the Phase in which the Graded Region Copy is Created.

Thanks, the existing is demo'd but I do recall having issues and having to redo the exisitng topography after attempting the graded region copy so maybe this is what is now causing issues. I also have an addtioinal alternative topography in the file but it's not attaching to that one. It's a bit complex. I'm getting a message saying file size is too big to attach.
Boy! I think your issues are spilling over to this thread. Either that or I need a new eyeglass prescription because I'm seeing doubles. Double posts that is. You too?
Yeah, I posted one twice as I hadn't replied to you directly so reposted to make sure you saw it. So it's saying 71 MB is the maximum file size I can attach but my file is 350 MB. Even my smallest projects are more than double that max.
I don't need the whole Project to troubleshoot. You can always temporarily Group the relevant elements together and use Save As to save the Group to a stand-alone RVT and then post that one here. Or you can try to compress the 350mb one - but not with WinZIP.
Great, I didn't realise the group save as was possible. Have attached a file with the existing topography, new topography, a building pad cutting the new topography, and one that won't cut the new topography.
Try these:
Set the view to Show New only.
Move the new topo a know distance away from the area, draw the pad, then move both back.

Yes, that worked. Is there a way to fix it so this is not required?
If you use Graded Region to demolished the existing topo and create a new one then the glitch normally doesn't happens. It only does when you have existing topo in the same proximity and it is not demolished. A few other ways if you don't want to demolish the existing topo:
- Save it to another model and link it in
- Move it to a Design option
Thank you, that has worked! I moved it to a design option along with the alternate new construction one and all seems good now. I orginally did do a graded region copy but from memory I realised down the track that the existing had disappeared in all my existing views. Is this meant to happen? I ended up remodelling it instead of copying it over from an od model as at the same time I got a more accurate site survey.

Yes. Graded Region is meant to demolish the existing topo and create a copy of it. It is logical because you shouldn't have two topos occupy the same space. If you only want to demolish a portion of the existing top then Split Surface then use Graded region.
