Profile from Surface Entities creates a profile from contours, triangular mesh, and other 3D drawing entities. The method is to draw a polyline as the profile centerline. Then the profile is derived from the intersections of this polyline with the 3D entities. For added accuracy in pulling the profile, include the triangular mesh as well as the contours.
File: Displays the name of profile to be created.
Beginning Station: Specify the beginning station for the profile.
Interpolate Endpoint Elevations from Beyond Profile Extents:
When
checked, the program will look past the ends of the centerline for
additional
intersections with 3D entities. These additional intersections will
then
be used to interpolate the elevation at the starting and ending station
of the centerline.
Extrapolate Endpoint Elevations to Extents of Profile: This
option
uses the slope of the last two elevation points of the profile and
calculates
the elevation of the endpoint from this slope.
Station by another reference centerline: When checked, the
program
will prompt you to pick another centerline polyline. The intersection
points
along the first centerline are then projected onto the second
centerline.
The profile then stores the elevation of the intersection with the
station
along the second centerline.
Breakpoint Descriptions from Layers: When checked, breakpoint
descriptions
are assigned based on layer name of surface entities. These
descriptions
are used in routines such as Input-Edit Profile and Profile
Report.
Ignore Zero Elevation Lines in Surface Model: When checked, any
zero elevations selected in the surface model are ignored.
Profile Offsets: Specify optional offset profiles. Enter offsets
separated by a space. Example: 30 -30 (to create 30' left and 30' right
offset profiles). After entering the offset values, press TAB to select
file
options described below.
Offset Profiles to: Specify whether offsets profiles should be
created as separate profile (.PRO) files, or included in a single
profile (.PRO) file. Only available if you specify Profile Offsets
above. Offset
profiles are automatically named by combining the profile name and the
offset. For example, if the profile is named NATGRD.PRO and you create
a 30' right offset profile, it will be named NATGRD30.PRO.
