Hi all,

First just want to say thanks to everyones input which has saved my bacon many times.  I've got a tricky issue which I think I know the answer to but I'm hoping the Revit Genius's have a solution for.

I have inherited a site model in which multiple Subregions (from multiple topo's) have been used to represent paths, roads, garden beds etc which is OK.  But the surrounding topo has been split and deleted resulting in two problems, I cant change the elevation or extend the subregion boundary.

I seem to be able to edit the subregion boundary but without change to the original boundary.

I am hoping you guys can tell me itis possible to alter subregions alone without having to delete and start again.

Fingers crossed.

Not sure I understand your problem  You can edit the subregion and pull it beyond your topo limit.  It just will not show until there is topo to sub region.  You can edit the existing topo to replace what was missing.  When you get the attached message, just do what it says.  Place your points on the edge then drag them out or drag out any existing points you may have to correct locations.  When the topo is extended to include your edited sub region, it will all show.

You're right WWHub, when I unravelled the nest of sub-regions and groups of surfaces I found the topo, extended it and then edited the the subregion to go where I wanted it to go.

I'm still a bit green when it comes to working with Topo's so I appreciate the help.
