Subregion is not showing up

[uaa061]

Hello All!

I am in need of some help. I am starting a new project and was messing around with the topography trying to put in the roads as subregions, but for some reason, it doesn't show up. Im not sure what the problem is because other subregions will show on the topography but not this one. And the only way I can see it is if I draw one over it and the error message comes up. Putting an image of that below. Ill also post the revit file and see if anybody can help. Thanks in advance.

I deleted some pads and it appeared.  You may want to delete the pads one by one and see which one causes the glitch then proceed with recreate it one way or another.

Split the topo across the subregion then it will show without deleting the pads.

I can imagine.  Even a 4-lane highway would be difficult to see.    

Do you really need 23 million square feet plus of Toposurface in one Project?   

If so, you might want to change your contour intervals. 

FWIW.

Building Pads too???  Is this a "site layout"?  Pads are hundreds to over a thousand of feet apart from one another.  Are Building Pads really necessary?  You might be over-modeling.  😉   

You might seriously consider splitting this 500+ Acre Toposurface into "bite-sized pieces" via Spilt Surface tool.
