Building pads creating slivers of topography where pads meet

[jasonVY8QC]

Where two circular building pads meet, I am getting some slivers that extend up from the building pad, and some slivers extending down which allow light leakage through the pad. You can see both instances in the image below.

I've searched the forums and have tried the suggested solutions, none of which worked. I've copied the circle edge from one pad to another and have also edited the topo surface and deleted all points in the region of the pad. Does anyone have any other suggestions?

It's been posted about may times on this Forum. 

Here's one:

Try using filled detail regions for the boundaries. sometimes they can help with issues like this.

I've gone through the suggested solutions in this forum post, and unfortunately none of the suggestions worked. Maybe this is just a glitch in Revit? I'm using Revit 2021

It's not a "glitch". Post your file and we'll tell you exactly what's going on - and IF there is a way to correct it.

If you could take a look at the file that would be great.

Can't download.  You don't need to share the whole file, just the topo / pad portion of it.

[jasonVY8QC]

The topo/pad portion of the RVT file is attached.

Thanks for your help!

You have overlapping pads. Edit pad sketch boundary and inset it a bit.  

...you know, I'm looking at this file and wondering what method you are using to retain the terraced earth.  Wouldn't there be walls or something to hold back the earth, or are the structures placed on the lower tiers just at the mercy of mother nature?

- copy the topo and sub-regions to the side for a record

- edit pad boundary and split segment at each intersection point, recommend clean up segment lines so you have one arc between each two intersection points (right now your arcs are splitted randomly), for example:

- copy paste aligned overlapping segments from one pad to the next, do not trace or use pick line tool to draw.

Thanks for the reply. Not sure I understand the overlapping pads you found in the file. Whenever I have pads overlapping, Revit gives me an error and does not allow the pads to overlap - does this not happen for you? Below you can see an image of the pad boundary where I copy/pasted the radius in the exact place to confirm the boundaries are in the exact same place. If I inset the radius slightly, the topography comes through between the two pads (see middle image).

Your point on the retaining walls is good advice to cover up some of these issues. This is a Schematic model, but we will have retaining walls which I can add between some of the pads. This issue that has become more of an annoyance is the pad extending in front of the glazing of the building which we cannot use a retaining wall to hide (see last image).

Any other advice on this?

Thanks!

[barthbradley]

The issue with the pads will be mitigated by the retaining walls. Obviously, the pad sketch boundary will be behind the RW - nowhere near the adjacent pad.  Know what I mean?

Awesome - that worked. Thank you!
