creating SIte Plan Model

[Andrew Mac]

I am trying to create a SIte Plan Model.  I have the appropriate point from a survey and have created the site model.  Is there a way to smooth out some of the translated points and make things look more smooth?

Without having seen the file,

normally you have to do this by adding further 3D points or supporting 3D Polygon Edges.

So to add more geometry (information) at places where you need more details.

Normally needed where steeper slopes or changes in slope occur.

@Andrew MacI looked at your v2017 file. Your survey points are pretty widely dispersed, so maybe it's not appropriate to add new estimated points between the existing. I'm guessing the surveyor decided that not much change in the areas with no data points, but that's an assumption. It could be too steep, or wet or slick to establish points, or deemed unimportant areas at time of survey, so large areas were not included. I'm just guessing.

 

Here are a few vwx things you could try to make the terrain model smoother:

1. Select the site model and switch the 3d Style to 3d Triangulated Contours, then in OIP>Site Model Settings, change the Smoothing Interval to 12" or 1". Default value is 0 which means the source data is used "as is", causing no change to look of the model.  Many of your data points are 10' to 20' apart, so any smaller value creates more triangles and a smoother appearance. I tried this, and it helps, but still not great. This only helps the 3d appearance, not the TopPlan contour display.
2. Similar - switch 3d Style to 3d Grid. Then, in OIP>Site Model Settings, change the 3d Grid Spacing to 5' or other. (It was set to 16'). This only helps the 3d appearance, not the TopPlan contour display.
3. Create some new contours or partial contours that represent what you want your site to look like and add them as Site Modifiers>Contours assigned to the Proposed status of your Site Model. Draw the new ones in a new layer as 2d polys (cubic spline mode is good) right over the funky existing ones, then convert each one (or copies) to 3d poly and assign desired z. Right click each one, choose Create Object from Shapes>Site Modifier>Contour. Note that Site Modifiers do not have to be on same layer as the Site Model.  Place the site model 2d and 3d display in Proposed status and update. 2d proposed TopPlan will have new, smoother contours. 3d status will also be smoother.
4. OK, you can add some source data as new, interpolated 3d loci or stakes if you are confident of no big changes in the z values between your survey points.  This causes more triangles, so can help TopPlan and 3d views. It's easy in v2017 & prior, a bit more convoluted in v2018.  Right click the Site Model>Edit Site Model Source Data.  Invoke the 3d Locus tool, then acquire snap points on a pair of your data points and place a new locus at the snap mid point. Make 4 or 5 loci, then exit the edit window and update the site model (existing mode, 2d and 3d) to see the results.  You can see how it works in this video, although the examples starts with contours rather than point data: https://vimeo.com/195211767

OK, post back as needed.
