| This Triangulation mesh was drawn as 3DFaces with the Draw Triangular Mesh command, and then colorized by elevation within 3D Viewer Window |
This command draws a triangulation (.flt or .tin) file as either
Surface Object, 3D LINES or 3DFACEs. Since 3DFACE entities can be
shaded within the 3D Viewer
Window or 3D Surface
FlyOver, or with the AutoCAD 3D Orbit command, this is an excellent
tool for visual surface inspection. 3D Lines cannot be
shaded.
The Surface Object is a custom object for displaying the TIN in
the drawing. This custom object also supports the EndPoint snap.
The main advantage of the Surface Object is with displaying large
TIN files because the Surface Object is more efficient than drawing
individual 3D Faces or Lines. The Surface Object requires Carlson
to be loaded to display.
In the options dialog, choose the method for how to draw. The
Use Inclusion/Exclusion Perimeters will prompt for selecting closed
polylines to limit the area where to draw. The Use TIN Colors will
color the entities using the colors for triangles stored in the TIN
file. Colors can be stored in the TIN files using commands like
Triangulation File Utilities, Road Network and Color Surface By
Layer. The Erase Previous will erase the existing entities in case
the TIN file has already been drawn.
Triangulation (.flt or .tin) files can be created by Triangulate & Contour.
Select TMESH File to Draw
Choose a triangulation (.flt or .tin) file from the file selection
dialog. You are then prompted for options:
If using Inclusion/Exclusion Perimeters, you will be prompted to
select them as the routine executes.
