Adjusting a vertical scale if possible on site model?

[og.skinman]

Hi! I'm wondering if I'm missing any possible adjustments for making a site model elevation look less dramatic. I've attached screencaps of two site models of the same plan from two different sessions, both from the right view: 

1. A smaller selection of the topography I'm working with - however I'm starting over with a new one because we now need to include all the other areas

(The elevations were put in with Survey Input > 2D to 3D Source Data)

 

2. The new site model that includes all other areas

(The elevations were put in manually this time after converting to 3D Polys)

 

TOTAL newbie here - I feel like I'm missing something very obvious..Thank you in advance for any help!

I’m not in front of VW atm but there is a setting to trim the depth of a dtm. Check through the settings. I can have a look at your files tmrw tho if you can’t sort it.

Thanks! I looked through site model settings and can't seem to find anything that changes it so that the 2' increment is not so dramatic. Would super appreciate if you pointed out specifically where that setting is

Hey @og.skinman.

 

If you crop the dtm you can trim out the lower parts of the model that you probably don't need.

@og.skinman I think the request is to display the terrain as if the z values of the source data were scaled down so that slopes are not as steep  = " less dramatic".   Is that correct?

 

If that is requested, then I don't think there would be a site model setting. Such a rescale would distort all the slopes, cut/fill calcs, retaining wall heights, surface distances, relationship to structures, etc.  But, you can make a wish for such a feature.  Maybe this is a common need?

 

As always, there are workarounds.  I can think of a couple:

1.  Make a new site model, but reduce the z value of all the source data by required factor (eg contours placed at half the z value).  Downside is that all the slopes, distances, cut fill, etc will be wrong.  But, the display will be closer to flat.

 

2.  Duplicate the correct site model, and convert it to a generic solid or a surface.  Scale the z value of this new object.  Downsides same as above, but it can be remade if the original is updated.  The source terrain remains correct for measurements and data.

 

Or, maybe you just want to crop the site model as @Boh suggests?

Or only show the parts within a certain z range?  Control for that is in the Site Model Settings - min and max elevations.

Thank you @Boh and @Benson Shaw both for responding! Yes, I should've explained it better but I definitely meant to ask what @Benson Shaw was talking about. Your second solution sounds perfect so I'm gonna do that. It would be a great feature tho.

Scaling of a terrain model only on the z access would create a "shorter" DTM however it's use as a context for a building in 3d views would not really work as the building presumably wouldn't be scaled. Out of interest why do you want to do this?

@og.skinman I would also be interested if you feel like ‘splainin’

Ok so I feel really silly. It was a simple SCALING problem that caused all my confusion. The second file I was working with on the full topography was just not scaled right..it's tiny. I'm sorry everybody!! It's been solved. I ended up with a pretty clean site model, thank you both for your time.
