Make Design Surface
This command makes the triangulation models for the design surface.
There are three surfaces that are created: initial unadjusted
design (bs), design after applying subgrade zones (zn), and design
after subgrade zones and topsoil replacement (fn). These surface
files are automatically named as "filename-bs.tin",
"filename-zn.tin" and "filename-fn.tin" respectively. The
"filename" is set to the name of the current drawing (dwg) file.
Also, the file extension will be .tin for the binary format
triangulation and .flt for the ASCII format triangulation. This
file format is set in Configure->Takeoff. The subgrade zones are
defined in the Define Layer Target/Material/Subgrade command. If
there aren't any subgrade zones for the Design surface, then the
design after subgrades surface with be the same as the initial
design surface. The topsoil replacement depths and areas are set
with the commands in the Topsoil Removal/Replacement sub-menu. The
topsoil replacement areas will lower the design surface by the
topsoil depth to leave room for the topsoil replacement. If there
aren't any topsoil replacement areas, then the design after
subgrade and topsoil surface will be the same as the design after
subgrade surface.
Before running this command, the layer names for the entities on
the Design layer target must be set in the Define Layer
Target/Material/Subgrade command. Also these entities must be at
their proper elevations. The entity elevations can be reviewed
using commands from the Inquiry menu and the elevations can be
assigned if needed using command from the Elevate menu. Another
prerequisite is that the Boundary Polyline must be set for the
site.
When the program finds errors in the existing entities, a Data
Error Log dialog reports these errors. Refer to the Make Existing
Surface command for more information on the Data Error Log
dialog.
