                    USING THE SURVEY DRAFTER

                          INTRODUCTION

The survey drafter is a menu driven software program that
converts user input raw survey data into an AutoCAD script file
format. Once the data is converted, the user begins a new AutoCAD
drawing and plots the survey data by executing the script file
created by the SURVEY DRAFTER program. Once the survey points are
plotted the drawing can be further edited as desired by the
AutoCAD user. The SURVEY DRAFTER also creates an ASCI format X Y
Z output file from the survey data that can be used as the
database for several different contour generating software
packages.
                      HARDWARE REQUIREMENTS

To use the SURVEY DRAFTER program you must have an IBM or
compatible computer with either two floopy disk drives or a hard
drive and 256K RAM. You must have the file SVY.CFG located in the
same subdirectory of your disk as the SURVEY.EXE main program.

                    SURVEY DRAFTER DATA FILES

The SURVEY DRAFTER stores survey data in either of two type of
files. A survey data points file or a traverse points data file.
The data file type depends on what type of survey you are working
with.

A survey data point file contains all survey points "shot" from
one particular transit setup. Each different transit setup used
on a particular survey must be entered into a separate survey
data points file. Each file would be given a distinct name.
A traverse points data file would be created to "tie" all
separate transit setup points used on one particular survey
together to create one survey plot. If your survey has only one
transit setup point, you do not need to create a traverse points
file. Only one data file need be started that will contain all of
the survey data points "shot" at the one transit setup point.


                         EXAMPLE SURVEY


Say a team of surveyors set out to survey a tract of land the
will require three different transit setups in order to cover the
entire site.  They initial setup at a given point they call
"PT.A". From this setup they turn angles and distances and record
elevations of 25 points.  They then determine that their second
transit setup point will be 125 feet at an angle of 45 degrees
from their first setup. They move their transit to the second
point which they call "PT.B". They take a backsite to point
"PT.A" and call this their zero line. They then turn angles
distances and record elevations for 25 points. They determine
that their third and last transit setup point will be 100 feet at
an angle of 180 degrees from their second setup point. They move
to the third point and setup again and call this point "PT.C".
They again turn angle, distances and record elevations for 25
points.

           USING SURVEY DRAFTER TO PLOT EXAMPLE SURVEY


                          THE MAIN MENU

            1) ENTER Data to an EXISTING file
            2) REVIEW/EDIT existing data file
            3) CREATE AutoCAD script + XYZ
            4) START a new survey data file
            5) PRINT a survey data file
            6) DISPLAY output files
            7) CONFIGURE Operating Parameters
            8) EXIT

All functions of the SURVEY DRAFTER are accessed thou the Main
menu. The following is a description of each menu option.

Before any survey data can be entered, the user must start a new
survey data files. To do this, choose option 4) from the main
menu. Upon choosing this option you will be asked if this is
really what you want to do. If is proceed, if not you will be
returned to the main menu.

You can start either of the two types of survey data files. Since
the example survey had more than one transit setup point, you
will need a separate survey data point file for each different
transit setup point and a traverse point file to "tie" all three
transit setup points together. You would start three (3) survey
data files named; EXAM-A, EXAM-B, EXAM-C and a traverse points
data file named; EXAMPLE. The names can be any valid DOS file
names. NO EXTENSIONS are necessary! The program will add the .SDT
extension for survey point data files and .TRV extension for
traverse files.

            1) ENTER data to an EXISTING file

After all the necessary data files have been started you may
proceed with entering the data. First you will want to enter the
random distances, angles, elevations and any notes recorded for
each of the three different transit setup points. In the example
survey the surveyors took 25 "shots" at each setup point.

Choose option 1) to enter data to an existing survey data file.
The data input consists of a DISTANCE to a point in decimal
format representing feet (125.5, 1015.25, 25.2). You must enter a
distance. You must enter an ANGLE to the point in degrees,
minutes and seconds format. The format must be like (125d15'25",
44d12', 179d): You may enter an ELEVATION at the point in decimal
format (101.5, 1215.25, 45): and you may enter a SURVEY NOTE
(4"tree, corner of parking, cl road, fire hydrant). The survey
note may have up to 16 characters with spaces. The point
elevation and survey note input are optional. If you do not have
an elevation or note for a particular point, just press <RETURN>
without entering any data. To exit the data entry sequence just
type the letter Q to Quit.

As you enter the data for each point it is displayed on the
survey data screen. If you enter incorrect data you can edit it
by entering the letter "E" at the distance prompt. You will then
be asked which data point to edit. Choose the data point number
that you wish to edit. You will then be prompted for new data for
the DISTANCE, ANGLE, ELEVATION and NOTE. To retain the existing
value for a given prompt, just press <RETURN> in leu of re-
entering the data. If you wish to enter revised data, type it at
the prompt and press <RETURN> to enter.

After entering the survey point data for each of the three survey
setup points, you should enter the survey traverse point data.
The traverse point data file will contain the distances, angles,
backsite-to, and side shot file name data.


For the example survey, the traverse file would contain the
following entries:

TRAVERSE POINTS
POINT #    DISTANCE        ANGLE        BS-PT        SS FILE
=================================================================
1        0              0               0            EXAM-A
2        125            45d             1            EXAM-B
3        100            180d            2            EXAM-C

Since their first setup point #1 was a random or other
established point in the field, the DISTANCE, ANGLE, BACK-SITE
POINT (BS-PT) are all 0. The name of the  file containing all the
survey points shot around setup #1, (or "PT.A" as the surveyors
called it) are in a survey data point file named EXAM-A.
Survey setup point #2 was 125 feet at an angle of 45 degrees from
point number #1. Thus the BS-PT would be 1. The SIDE SHOT FILE
(SS FILE) that contains all of the survey points shot around set
up #2, (or "PT.B")  are in the survey data point file named EXAM-
B. The third setup point was 100 feet at an angle of 180 degrees
from point #2 or "PT.B". The BS-PT was point #2. The file
containing the side shots for this point are in a file named
EXAM-C.

            2) REVIEW/EDIT existing data file

Choose this option from the Main Menu when you wish to review or
edit data that has previously been entered. When you choose this
option, you will be asked whether you wish to edit a survey data
point file or a traverse point data file and the name of the
file. Data editing is exactly the same as editing data while
entering it. You select the point # to be edited an either enter
new data or press <RETURN> to keep the current value.

            3) CREATE AutoCAD script + XYZ

Choose this option when you are ready to convert the raw survey
data into an AutoCAD script file format. You must enter the
following information to create an AutoCAD script file.

    NUMBER OF TRANSIT SET-UPS------------------->>3

Enter the total number of different transit set-ups used in your
survey. For the example survey you would enter three (3). If your
survey only had one, enter 1.

    NAME OF TRAVERSE POINT FILE----------------->>EXAMPLE

Enter the name of the traverse point file that describes the
distances, angles, back-sites and side shot file names to use in
your survey. For the example survey, the name of the traverse
file was example. If you have only one survey setup point, you
will not be asked for a traverse point file name.

    DO YOU WANT A LINE ON TRAVERSE (Y/N)-------->>Y

If you answer "Y" AutoCAD will draw a line connecting each of the
different transit setup points. If you answer "N", no line will
be drawn. If you have only one survey setup point, you will not
be asked whether you wish to plot a traverse line.

    DO YOU WANT SIDE SHOT FILES PLOTTED--------->>Y

Normally you will want to plot the side shot files. These files
are the survey points shot around each of the different transit
setup points. If you answer "N", then only the points where the
transits were setup would be plotted. If you have only one survey
setup point you will not be asked if your wish to plot side
shots.

    NAME FOR THE AutoCAD SCRIPT FILE------------>>EXAMPLE

Enter the name you would like to give the output AutoCAD script
file created from the survey data. NO EXTENSION is necessary! The
program adds the .SCR extension which is the default for an
AutoCAD script file.

    X VALUE FOR INITIAL TRANSIT POINT----------->>5000

Enter a value to use as the base X coordinate for calculating all
other survey points. The value can be any number, but if it best
if it large enough to avoid getting calculated negative values.

    Y VALUE FOR INITIAL TRANSIT POINT----------->>5000

Enter a value to use as the base Y coordinate for calculating all
other survey points. The value can be any number, but if it best
if it large enough to avoid getting calculated negative values.


    INITIAL SURVEY ANGLE ----------------------->>0d

This angle is a correction angle to rotate the entire survey when
it is plotted in AutoCAD. AutoCAD always assumes that the zero 0
degree reference is to the right side of your screen, unless you
configure it differently. The survey angle you enter, rotates the
entire survey by adding the degrees you enter to the default
AutoCAD zero angle. The survey itself is not altered, only it's
orientation or (north) in the AutoCAD drawing. The angle you
enter must be in the same format as other angles entered in the
program.

    HEIGHT FOR AutoCAD TEXT -------------------->>10

This is the height that you wish to assign to all text plotted in
AutoCAD. Your default text style in AutoCAD must accept a text
height input. If it does not, your will get an error when running
the script file.

WHAT THE SURVEY DRAFTER PROGRAM DOES.....

The conversion routine reads the point distance and angle from
the survey data file. It then calculates the X and Y location
of that point. The calculation utilizes the laws of Sin and
Cosine for right triangles when it solves the X and Y distances
from the survey starting point. The routine then writes the X and
Y coordinates of the point to the user-named script file along
with the AutoCAD "point" command. The point number, elevation and
survey note for that point are written to the script file along
with the AutoCAD "text" command. A command sequence to change the
current layer to a "TEXT" layer is written to the script file
prior to the text command so that all text will be on a separate
layer. A command to change the current layer back to the "0"
layer is written to the script file before the next point is
calculated. Once the data is converted to a script file, the user
is ready to EXIT the program and begin a new AutoCAD drawing.

             5) PRINT a survey data file

Choose this option from the main menu when you wish to print the
contents of either a survey data points file or a traverse points
file on a line printer. You must have a printer connected to your
parallel port to use this option.

            6) DISPLAY output files

Choose this option from the main menu when you wish to display
the output files created by the program. The following display
menu will be shown. Choose the option that suits your wishes.

                Display Output files
            ===================================
            1) Display AutoCAD Script file
            2) Display X-Y-Z-Note output file
            3) LIST Survey Data (.SDT) files
            4) LIST Script output (.SCR) files
            5) LIST XYZ output (.XYZ) files
            6) RETURN to Main Menu
            ===================================


            7) CONFIGURE Operating Parameters

Choose this option when you wish to set or change the default
settings of the SURVEY DRAFTER programs. The following variables
are available for your customization.

            SURVEY DRAFTER CONFIGURATION
            =================================================
            Number of Survey Data point in a file ---->>250
            Create an AutoCAD Script file (Y/N) ------>>Y
            Create an X Y Z Output file (Y/N) -------->>Y
            AutoCAD text Height ---------------------->>10
            Initial X coordinate for calculations ---->>10000
            Initial Y coordinate for calculations ---->>10000
            Do you want point plotted in 3D (Y/N) ---->>N
            Initial Survey Correction angle (North)--->>0d
            ==================================================

The AutoCAD text height, X and Y initial coordinates, and survey
correction angle can be changed any time you create a output
file. Pressing <RETURN> at any prompt will accept the default
values that you enter in this configuration menu.

                      8) EXIT

Choose this option to exit the SURVEY DRAFTER program and return
to DOS.


                      PLOTTING THE SURVEY

To plot the converted survey data a user must take the following
steps:

1) Copy the script file containing the converted survey data to
the AutoCAD sub-directory of the hard disk.

2) Begin a new AutoCAD drawing

3) Set the new drawing units to be decimal format

4) Set the angle format to be in degrees, minutes and seconds.

5) Set the drawing limits to be large enough to contain the
   entire scope of the survey

6) Set the AutoCAD variable "pdmode" = 3 and "pdsize" = 3
   (This setting is suggested for best results, it is not
    mandatory)

7) Create a layer called "TEXT" (if not already existing)
   The CURRENT TEXT STYLE MUST ACCEPT both text height and angle
input.

8) Set current layer to be "0"

9) ZOOM ALL

10)Enter the SCRIPT command and respond with the name of the
script file you created.

AutoCAD will plot the survey points and note them appropriately.
Once the survey data has been plotted the user may change the
unit format, drawing scale, limits, etc. to meet their specific
needs.



              USING A LISP ROUTINE TO INTERPOLATE

Users wishing to take the plotted survey data a step further
might want to use a lisp routine to interpolate between random
survey points. In the example lisp program,"INTERP.LSP", the user
must load the routine and then enter the command "INTERP". The
routine prompts the user to select two (2) survey points.  He/she
uses a pointing device to select two survey points to inter-
polate between. The lowest elevation point must be selected
first. The lisp routine then asks for the known elevation of
each point, as well as the elevation of the first interpolated
point. The user must enter this data from the keyboard. The lisp
program then proceeds to plot the interpolated points between the
two user selected points. Each point is noted with the
appropriate point elevation, based on the users original input.
