hi all, i'm using Revit 2013. trying to do a toposurface for the first time. sorry if this is too basic a question, but as you can see in the attached images. i tried to do a subregion for the roads, and parking areas on the site. they turned out like junk. it's in the right locations, but only part of the subregions show. is there a setting that i can use to control this? i need the roads, and parking areas to show completely.

I wonder if this is a graphics card issue.  Try updating your card and see if that fixes the problem.

thank you for the imput. however, i just updated my driver and the same results. i'm using a Nvidia Quadro FX3700. that card is more than capable of running Revit. any other ideas.

This might be a "duh" moment, but double check and make sure there are not two topo objects (like accidentally duplicated into the same place). A subregion would only cut one if there were dups... or try clicking one and isolating it and see if it still looks that way.

only one. it just looks like garbage. and after all the time it took to create it, i want to be able to show it off.

Have you used the Graded Region tool after creating the topo?

no, i didn't use the grading. i made the toposurface, then i added a subregion, and then i placed a building pad. and the problem is only with the appearance of the subregion. the lines for the subregion are right. it just looks like it is not laying on the surface like it is suppose to.

there are several ways to do what you are trying to accomplish. one way is to cut the topo surface into two diferent surfaces and then drop the parking area and driveways down 4 or 6 inches. another is a method I believe it was proposed by eladeos several years ago. then there my tedious way. which is the most effective and accurate. There is also EaglePoint Software called Siteworks which is an add on to Revit.

i just want to start by thanking all of you that responded to this post. after looking into this more, i have found the problem. when i created the toposurface, i imported a 2D .dwg and placed it at an elevation that was 300 feet above the target site. then i made the topo points by following the dwg. that all worked great, even though it takes a lot of time. when i was creating the subregion i used the pick line tool and picked the lines from the dwg, that was the problem. it was not on the same elevation, so Revit got confused. i deleted that subregion, and made a new one by drawing the lines manually and i got exactly what i was trying to do.
