DWG Point markers for terrain data

[SHCanada2]

The survey around here for residential typically only has ASL elevation at certain points on the site.

 

I am trying to convert these to elevation points in terrain, if possible.

 

My first step was to import the DWG into CA. But I noticed that what look to be point markers in the DWG dont actually import in CA (I tried the different options in the import, no luck).

 

Am I missing something or is this a known limitation:

 

DWG with only property line and elevation layer data turned on

 

 

CA with all layers (rotated):

 

 

but even if I could get them in as "X" or something else, I do not see any option to convert to a CA elevation point. Is there a way?

 

My method of last resort will be overlaying the PDF and creating elevation points in CA overtop of the X point markers in the PDF

Best solution is to use "Elevation Lines" vs "Elevation Points".  The Terrain will look much better.

It might not be real easy to define just a few elevation lines but if you can do that running completely thru the Terrain Boundary you will get the Terrain to be pretty smooth and then you can use additional Terrain Tools to fine-tune.

I was pondering how to do this. The survey is the survey so to speak. any interpolation will be guessing. I was hoping CA's algorithmic guessing plus any tuning would be better than mine.

 

Are you saying just the elevation points will be a nightmare to tune, and I am better off making at least a first pass guess with elevation lines (ensuring the elevation line matches the point in at least the one location and does contradict any another) and tune from there

When I import a dwg or dxf file into CA I have to specify the points layer as elevation data.  There has to be an underlying polygon that will either becomes a terrain perimeter automatically or I specify that layer is a terrain.  Without the terrain the points never appear, just the adjacent data.  When that happens I will create a terrain perimeter that encompasses all the data, then copy-paste this terrain to a new blank file.  Now import the dwg/dxf and points will appear.  Post the plan if this doesn't work.
