------End Menu Loading Section--------

For step by step instructions for our DPpoints menu items select "Step by Step Points" from the "Table of Contents" menu above.

Before you begin go to Drafting -- Drawing Setup
Drawing Setup - Select English or Metric units -changes the ltscale and labeling precision, changes dimscale to the scale of the drawing, it changes textsize to one tenth the drawing scale (English) and to 3mm (Metric) and it changes other dimension variables. You may use notepad to edit dpset.lsp in the Dpcogo directory if you want to change  or customize these settings.

Set points
Survey and Cogo does not use AutoCAD® point objects, It uses blocks which contain the point node, a point number, point elevation and point description.
Set points by entering Northings & Eastings (coords) or pick a point (select).
(if you pick a point on a 3D object, the elevation will be used for the point).
You may also set points by Traverse, Sideshot, or by entering a station and offset along an alignment.

Note: Whenever you add points to the drawing a user definable block can also be placed there automatically, such as an iron pipe or a power pole etc. -
See Create key descriptions below.

Point blocks
There are two point nodes placed for each point. One node is placed at the elevation of the point on layer 3D_NODE to be used for surface modeling programs or for drawing 3D lines etc. The other node is placed at elevation 0 on layer 2D_NODE to be used for 2D drafting.

The "Reassociate points" command will move all 2d nodes to their proper location in relation to the 3d nodes in case you move points manually and get them separated.

NOTE:
The point number is on layer DPNO, the point elevation is on layer DPEL, and the point description is on layer DPDES.

Create key descriptions
Selecting this option brings up a dialog box in which you may enter point descriptions that will cause a block to be placed along with the point, such as an iron pipe or a power pole. A block (drawing file) with the same name as the description must be placed in the c:Program FilesCogoSoftwareDpcogodwglib  directory - a sampling of some descriptions and blocks are included with the program. The list of descriptions are kept in the file c:Program FilesCogoSoftwareDpcogodwglibdpdestd.lbr Please note that the block will be scaled by the linetype scale of the drawing. If you are drawing at a 20 scale then the linetype scale (LTSCALE) variable should be set to 20. If you use the Set drawing scale option on the drafting menu, the linetype scale will be automatically set.

The key description must be the first part of the description before any spaces.

An example: Lets say the key is ip for iron pipe - when the program sees the key ip, it places the block ip.dwg at the point location.
The following are valid descriptions:
ip
ip bent
ip 1/2"

Create line descriptions

This command is being phased out. The import linework command will automatically find line descriptions from the point file.

Selecting this option brings up a dialog box in which you may enter line descriptions that will cause a layer to be created and linework to be drawn on it from a point file (See Import line file).
If a line description was set up for ep, then any line name beginning with "ep" would be placed on layer ep.

Downloading a Data Collector
Use the software that came with your Data Collector to download to a file in one of the following formats:
Point Number, Northing, Easting, Elevation, Description (PNEZD) or
Point Number, Easting, Northing, Elevation, Description (PENZD).
This file may then be imported using the import points and/or the import linework commands.
Point symbols and lines are automatically drawn.

Example: Let's say you are downloading from a Sokkia SDR33.
If you use the ProLINK Comms program, which came with the Sokkia SDR33, you will need to send the data from the SDR33 in POS view. This option is under the Communication Menu. Once the data is in ProLINK Comms as coordinates then there is a format conversion that will convert to the format that you wish.

Point display

Points display on will set pdmode to 3 (displays an x) and pdsize to 0.03.
Points display off will set pdmode to 1 (no display).
Points display select will allow the user to select a point display mode.
Zoom to points by number will center the point in the current display.
Renumber points add a numeric value (+ or -) to existing point numbers.
Select points by number will make a selection set of points by entering a range of point numbers. Use the previous selection set "P" option to use these points in another command (such as nodelist or twist).
Select points by description will make a selection set of points by finding a matching description. Enter the description to find. Use the previous selection set "P" option to use these points in another command (such as nodelist or twist).
Change point layer by number will move points to a different layer by entering a range of point numbers. Enter the range of point numbers and the layer to move to (the layer must exist in the drawing).
Change point layer by description will move points with a certain descrption to a different layer. Enter the description to find and the layer to move to (the layer must exist in the drawing).
Add text to elevation by desc. Will add text to an elevation , such as adding TC= to an elevation (i.e. TC=600.00), by finding a matching description.
Add text to elevation by select  Will add text to an elevation , such as adding TC= to an elevation (i.e. TC=600.00), by selecting a point or group of points.
Reset elevation by desc. Will reset the elevation text to the elevation of the point by finding a matching description.
Reset elevation by select Will reset the elevation text to the elevation of the point by selecting a point or group of points.
 

Boundary Traverse and Sideshot
Set points using a boundary traverse or sideshot (use vertical angle or difference in elevation). Select a point to occupy by point number, or pick a random point graphically, then select a point to backsite - enter as many sideshots as you need. When done press enter - the program will move you to the last point that you set and backsite the point that you were on before - continue with traverse or sideshot. Note: In order to set on or backsite an existing point in the drawing you must enter the point number.

Draw Traverse - Draw by entering bearings and distances and curves. Good for inputing an existing boundary.

Radial Stakeout
Enter a point number to occupy. Then enter a point number to backsite. You will be prompted to create or select a file. If you select an existing file, the new data will be appended to it. You may graphically select all the points that you want to include in the stakeout report, or you can enter a range of point numbers. You may now open the file in notepad or any other text editor and print it out.

Inverse
Inverse points by entering point numbers. You will be prompted for the first point number and then the second point number.
A bearing and distance will be displayed at the command prompt.

Intersections
Find intersections by Bearing - Bearing, Bearing - Distance, Distance - Distance, Line - Arc, and Point offset to a line.

Bearing-Bearing:
You will be prompted for the first point number and bearing (or enter two point numbers for bearing) and then the second point number and bearing (or enter two point numbers for bearing), the intersection will be displayed at the command prompt and you will be asked if you would like to set a new point there.

Bearing-Distance:
You will be prompted for the first point number and bearing (or enter two point numbers for bearing) and then the second point number and distance, the intersection will be displayed at the command prompt and you will be asked if you would like to set a new point there.

Distance-Distance:
You will be prompted for the first point number and distance and then the second point number and distance, the intersection will be displayed at the command prompt and you will be asked if you would like to set a new point there.

Note: If two answers are found, you will be asked to choose the answer you want to use.

Line-Arc:
You will be prompted for the first point number and the second point number to define a line, then you will be prompted for a point number at the center of the arc and a radius, the intersection will be displayed at the command prompt and you will be asked if you would like to set a new point there.

Point offset to a line:
You will be prompted for the first point number and the second point number to define a line, then you will be prompted for a point number, the bearing and distance from the point perpendicular to the line will be displayed at the command prompt.

Draw by point number
You may draw a line from point to point by entering the point number.

Import / Export
Import points from an ascii file or export points to an ascii file. A file is created in a variety of formats (including: Point Number, Northing, Easting, Elevation and Description). You may also create a Point List for viewing in the same format.

Import line file
Linework may be created in the drawing by reading a point file with linework coded into it. This may be the same file used to import the points. Line descriptors must start with a "." right after the key description (if any). The line name can be anything, such as "line1" or "line2" (An example would be .line1). If the line is on a curve place a "-" after the "." (An example would be .-line1).
To end a line, place a "!" after the line descriptor (an example would be .line1! ). This will stop the line at this point and it will restart at the next descriptor for that line.
You may also end a line by placing ".." in front of the descriptor (an example would be ..line1 ). It is preferred that you use .line1! instead of ..line1 to close a line.
Only one control code (the last one) will be honored in a line descriptor.
To close a line, place a "+" after the line descriptor (an example would be .line1+ ). This will close the line back to the beginning point.
To join the last point shot into a line, place a "*" after the line descriptor (an example would be .line1* ). This will add the last point shot into the line, inserted before the current point.
You may place several line descriptors on one point (an example would be .ep!.bc.sw ).
In the following example there is an iron pipe found bent on the edge of pavement. To code the iron pipe we have set up the key description of "ip" and the line name is "ep1" also we want to note that the pipe was bent, thus the description would read in the following format: key description (if any) "." Line name, a space, and then the note. Example:   ip.ep1 bent.

The following are valid line descriptions:

.ep1
ip.ep1
ip.ep1 bent
ip.ep1 some note

Notice that there are no spaces till the beginning of the note.

If a line description was ep1, then line ep1 would be placed on layer ep. Any line name beginning with "ep" would be placed on layer ep.
 

Manipulate points
