Hello,

I have created a topo surface with a couple of Subregions and a Building Pad. After copying it through the Graded Region tool, I adjusted the topography and the outline of the Subregions and added a second Pad in an area adjacent to the first (for a building addition).  While the New Const. Phase works as expected: (image 1 below)

The existing phase shows a strange artifact: It looks like the pad is starting to cut something, but the cut piece is still visible. (image 2 below)

I have tried all common sense things I could think of.  The topo surfaces are attributed to the correct Phase.  The building pad in question is attributed to the Existing Phase, and it correctly cuts the topo surface in New construct. phase, but fails to do so in the Existing Phase.  The second pad, created in New Constr. correctly cuts the New Phase.   

Any ideas how to fix this?

I appreciate any comments.

Raffi,

Raffit,

Try this and see.

On Existing phase view, identify and select the graded topo and assign "Phase created=Existing" & "Phase demolished=None". Select the original existing topo (which was before graded) and assign "Phase created=Existing" & "Phase demolished=Existing".

 On view properties, set the "Phase filter=Show complete" & Phase=Existing".

I guess this is applicable only till you start something on the next phase - not much complicated though. Need to copy the graded topo on the new phase, assign "Phase demolished=new phase" for the previous graded topo and so on....

I learnt this from a post here - could not recollect at this moment. A search would definitely help.

Good luck.

gprakash,

Thank you very much for the response.  It works marvellously except that in the existing phase the pad, created in New Construction leaves a big blank spot.  No matter what I did, I could not get over that.  Will continue with the experiments over the weekend.

I appreciate the prompt reply and the tips.

 Cheers,

Raffi

Hi,

Glad that it worked. The process wrote on my first para was just undoing the modifications done to the orignal phasing parameters ;-)

For the big blank spot on a new phase, try this - http://www.revitcity.com/forums.php?action=viewthread&thread_id=5959

Cheers.
