Reqesting Revised or New Inclusion Functionality in DTM

[James Shaw]

Having come from recently using Eagle Point I would like to see Carlson
improve what I perceive as a weakness in their surface modeling routine.
When I choose an inclusion perimeter, the TIN is still being theoretically
pulled to a point outside the inclusion area. While this effect can be
limited by being careful about your selection set and triangle lengths there
are still situations where the parameters can not be limited enough to
prevent a false TIN image. The way Eagle Point handled the inclusion
perimeter was that any TIN that came in contact with, or fell outside the
inclusion area was completely eliminated. As of now our only option is to
graphically create the TMESH and edit out the questionable TIN lines and
then Contour from Triangulation, but this presents another problem...The
options for contours, contour indexing, and contour labeling are absent in
the Contour from Triangulation routine. I feel Carlson needs to improve on
the consistency of some of their commands. There is no reason that the
Contour from Triangualtion does not have similar tabs and options as the
Contour from TIN or Triangulate & Contour commands. Don't get me wrong, I
love SurvCADD, I just see some areas for improvement.

Comments and feedback from Carlson as well as other users are encouraged.
Thanks.

I am using a 3d poly for my inclusion boundary and I have the "use tin bdry
for points" (or something like that) checked. My tin is not going outside
this boundary as long as I TAG it as a tin bdry inclusion line. It takes
longer to draw the 3d poly for the tin bdry, but it's worth it. If I have
misunderstood your problem, ignore this post reply.

If I understand you Jack, are you saying that you run a 3d poly around the
entire boundary? If that is what you are doing, are you running it from
point to point? We have looked at this solution and it has some benefit,
but this still seems to be a problem in areas where you have curved
breaklines to begin with, such as a top and bottom of curb around a fillet
at the extents of the survey. Please respond so that I know if we are on
the same page or not.

Thanks,

James

James,

I just now saw your response to my reply. XML now has a 3d Arc function
included in the "3d poly" routine in the DTM module. It is VERY quirky and
it's hard to figure out how it works, so I prefer to use AutoCAD's 3d poly
routine when just drawing point to point, but wherever a 3d arc is required,
such as curb, I use the SurvCadd XML 3d polyline for the curve and then 3d
join to the rest of my AutoCad 3d polyline. Yes, I am clicking every point
that would be considered an "outside perimeter" point for my DTM. The SC 3d
Polyline works best by using the 3 point method, typing "S" for second
point. I hope this helps.
