Drafting a Closed Traverse with local coordinates using Civil 3D
-
Background - desire is to create a map from survey measurements (horizontal angles and horizontal distances) done with a total station. This wiki uses Autodesk Civil 3D to create the map.
Step 0. open Civil 3D 2015 Imperial which should include a template which has the line and curve label styles (e.g. bearing over distance label style) already defined.
Step 1. Drawing Setup - Text Style and Dimension Style
STYLE - Text Style annotative, font name Arial, Height is 0.1389 inches (10 pt / 72 pt per inch), then press Set Current button.
DIMSTYLE - Annotation Style, Modify button
Symbols and Arrows tab - Arrow size <b>0.05</b>
Text tab - Text style <b>Annotative</b>
Fit tab - Fit options <b>Text</b> and Text placement <b>Over dimension line, with leader</b>
Primary Units tab - Precision <b>0.00</b> and Units format <b>Degrees Minutes Seconds</b> with Precision <b>0d00'00“</b>
Set Current and then close the dialog box
Set Model space Annotation scale to 1”=200' (bottom right side of Civil 3D window)
Step 2. Drawing Setup - Label Style - change the precision of the label
Use the Settings Toolspace ? General ? Label Styles ? Line ? Bearing over Distance, then double click or right click Edit from the context menu.
click the Layout Tab
Component name: Bearing, Property Text ? Contents. Click the Value field to reveal the button with the three dots. Click this button.
delete the contents in the left window
Change the precision to 1 second
click the white arrow button to copy the contents into the left window. Click OK
-
Turn on <b>Show Annotation Objects</b> in the status bar
Turn on <b>Add Scales to Annotation Objects when the Annotation Scale Changes</b>
Step 3. Drawing scale 1“ = 200 ft (use to plot on 8.5×11 paper)
Step 4. Layers
V-SURV-LINE draw the survey traverse lines on this layer
V-SURV-LABEL add the interior angle annotation and bearing over distance labels on this layer
V-NODE-TEXT add the point/station label (e.g. A, B, C, D, E)
Step 5. Layout setup 8.5”x11“ Plot
Step 6. draw the basis of bearing line
LINE 10000,5000
'ZD <i>transparent command - azimuth direction</i>
234-17-18 <i>enter azimuth angle in degrees minutes seconds and use a dash - to deliminate/seperate the values of 234°17'18”</i>
500 <i>distance isn't given so just assume 500 ft</i>
Step 7. label the basis of bearing line
in the Civil 3D Ribbon, click the Annotate tab, then click the Add Labels button to reveal Add Labels dialog box
change feature to Line and Curve
change label type to Single Segment
change Line label style to Bearing over Distance
click the Add button
in the drawing display/model space window, click the basis of bearing line
Step 8. draw line AE
LINE
with the object snap on, click point A on the basis of bearing line
'AD transparent command - angle and distance
select point W on the basis of bearing line this sets the reference line for
AutoCAD from which it can turn an angle from
151-52-24 enter the WAE observed angle to the right of 151°52'24“
285.13 enter the distance between AE
ESC escape out of the angle and distance transparent command
ESC escape out of the line command, should now be at the
AutoCAD command prompt
Step 9. draw line AB
LINE
with the object snap on, click point A
'AD transparent command - angle and distance
select point E on the AE line this sets the reference line for
AutoCAD from which it can turn an angle from
100-45-37 enter the observed angle to the right between backsight E and foresight B which is 100°45'37”
647.25 enter the distance between AB
Step 10. draw remaining portion of the traverse
still in the LINE and 'AD commands, continue entering the angles to the right and the distances for points B, C, and D
Step 11. misclosure at E
do not snap or close the traverse a point E.
need to balance/adjust the angles using the procedures on p. 241 of Elementary Surveying by Ghilani and Wolf, 12th Edition
need to computer preliminary azimuths or bearings
compute departure and latitudes for each line
compute relative precision
Step 12. label traverse with the bearing over distance style
Step 13. dimension the interior angles

Drafting a Closed Traverse with State Plane coordinates using Civil 3D
Step 1 - Open Civil 3D 2015 and click Start Drawing from the startup screen
-
Step 3 - add aerial photo

Point Name, X, Y
TBEA-SE-BC-01,786860.885,26741848.506
TBEA-E-PK-01,786866.220,26741974.941
Step 4 - draw Basis of Bearing line
From the above two points, enter the following
LINE 786860.885,26741848.506
#786866.220,26741974.941 (by default
AutoCAD uses relative coordinates, to use absolute coordinates either use
# before the coordinate pair of second point or change
DSETTINGS)
Step 5 - Assign State Plane Coordinate System. Application Menu > Drawing Utilities > Drawing Settings > Units and Zone tab
Zone Categories - USA, Nevada
Available coordinate systems: NAD83 Nevada State Planes, East Zone, US Foot

Inaccessible Point Problem
“It is sometimes necessary to determine the elevation of a point that is inaccessible. This task can be accomplished by establishing a baseline such that the inaccessible point is visible from both ends. As an example, assume that the elevation of the chimney shown in Figure 11.12 is desired. Baseline AB is established, its length measured and the elevations of its end points determined. Horizontal angles A and B, and altitude angles, <i>v</i>
1 and <i>v</i>
2 are observed as shown in the figure. Points I
A and I
B are vertically beneath P. Using the observed values, the law of sines is applied to compute horizontal lengths AI
A and BI
B of triangle ABI as AI
A = AB sin (B)/sin
