TIN volume surface shading

945 Views, 12 Replies
02-10-2012 09:56 AM

So I have a tin volume surface comprised of proposed and existing models for a large earthwork site. I would like a detailed cut fill diagram for presentation to project owner. The site involves cuts and fills up to 30' depths. I would like to be able to represent not only cuts and fills, but give a visual representation of the depth of cuts/fills (ie darker blues and reds in the deeper areas, lighter in the shallow areas). Is there a simple way to do this without setting up 100 different colors of blues and reds in the volume surface properties analysis tab? I have seen contractor software that performs this function rather easily.

If you have a Tin Volume Surface then why not just use that for contours, It cannot get much easier than that.

I would like a much more visual representation of the earthwork required rather than just using contours. I want the owner to be able to see exactly what is happening on the site (via differing cut and fill shading) and not have to try and interpret contours.

You do know that these contours represent cut and fills?  Positive for fill and negative for cuts.

Im well aware of what the tin volume srf represents.

 

Here is an example of what I wish for. I gather this is not something I cant expect from C3D.

You can show depths of cut/fill by

 

1. Applying a surface style that displays elevations.

2. Perform an elevation analysis on the surface.

 

You can also create a table and get the area and volume.

 

Let me know us you need more detail

Use 2D elevation banding and set up the elevations tab with what you want.

O.K. so I thought I'd get "cute" to try something other than C3D's color banding so that the OP wouldn't end up with the TIN looking so jagged for the analysis - but it crashed C3D w/o so much as a CER... you can try:

 

From Prospector right click on the surface and select "Export to DEM"  You'll need to set up a grid spacing and CS like "UTM83-13" since the USGS DEM format (according to the dialog boxes) doesn't support a state plane projection

 

From the Mapwspace, FDO connect to the DEM & stylize for color grading with as many rules as you want for a color ramp from red to blue or whatever.  stylizing is where i crashed...

no such luck - keeps crashing.  probably due to exporting out a imperial (us survey ft) surface to a metric CS dem and bringing it back in.  and the DEM file became 3.1MB for my 1.6MB drawing.... can't say I'd recommend this method at all!
