Editation of TIN
|
Dynamic editing of
TIN
If it is enabled (Settings DTM) then with every change of TIN
the contour lines will also be recounted (with the exception
of a hole).
Warning:
For proper functioning Xdata must not be removed
(attached to the TIN) . Configuration used when creating
contour is stored in XData (degree of smoothing, step
contours etc.)

Correction
of vertex-height of TIN
from command line:
sngDMTZ
toolbar: 
This function fixes selected vertex to the value set by
user.
The following prompts are
displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
Pick triangle
vertice you want to correct: adds new value.
Removal of
TIN vertex
from command line:
sngDMTZV
toolbar: 
Removes selected vertex and retriangulates the area.
The following prompts are
displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
Delete
vertice: pick vertice.
Removal of
triangles from TIN (hole)
from
command line:
sngDMTRemove
toolbar: 
Removes
selected triangles according to location set by user and
alternatively creates a hole in TIN.
The following prompts are
displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
Pick boundary
of hole: enter the boundary vertices.
Adding a vertex to TIN
from command line:
sngDMTP
toolbar: 
Adds
a vertex to TIN and retriangulates the area. Vertex cannot be added
if it is outside of TIN.
The following prompts are
displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
Pick new
vertice: enter new vertice inside triangle
mesh.
Mark edge as breakline
from command line:
sngDMTOH
toolbar: 
Function marks or unmarks
edge as breakline.
The
following prompts are displayed:
Select edge of
triangle mesh: select
object <TrojSit>, generated function
Triangle mesh.
Insert new edge to TIN
from command line:
sngDMTRetr
toolbar: 
Function inserts new edge
to TIN (retriangulation).
The
following prompts are displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
New edges as
<Polyline>/Vertices:
Delete edge triangle
from command line:
sngDMTEBT
toolbar: 
Function deletes edge
triangle from TIN (this is triangle - when deleted, no orphan
vertice will be created).
The
following prompts are displayed:
Select triangle
mesh: select edge of
TIN.
Swapping triangles
from command line:
sngDMTPH
toolbar: 
Function swap edges two
adjanent triangles.
The
following prompts are displayed:
Select edge of triangle
mesh: select edge of
TIN.
Compression
of TIN
from command line:
sngKOMPR
toolbar:
It
will check and possibly remove errors in the TIN or redundant
vertices that may have arisen by editing the triangular mesh. This
is needed if we are interested in the minimum and maximum height of
the TIN, it is determined from all vertices, even unused
ones.
The following prompts are
displayed:
Select triangle
mesh: select object
<TrojSit>,
generated function Triangle mesh.
