This command translates points in a coordinate file from one
coordinate position to another. The delta X, Y,
and Z can be entered
directly or calculated from original and destination coordinates. The
original and destination coordinates can be entered
directly, specified by point number, selecting the point number from a
point list by selecting the list
icon, or selected from the screen by selecting the pick icon. Once
these points have been specified, the Delta X,Y,Z, if Process
Elevations is checked ON, fields will be filled in with their
calculated values. Any
points in the drawing will be
updated automatically in addition to updating the coordinate file.
Define Translation By Angle/Distance requires a specified direction, Northeast (NE), Southeast (SE), Southwest (SW), Northwest (NW) or Azimuth (AZ) along with a specified distance in order to perform a translation. Once the direction and distance are entered, the Delta X,Y,Z will be calculated. This is a useful command when you know that the job needs to shift, for example, to the Northeast 25 degrees for a distance of 100 feet. Here you would simply type in 25 in the Angle (dd.mmss) field, choose NE in the Type field and then enter the distance of 100 in the Distance field.
With Process
Elevations checked,
all elevations will be
translated by the specified or calculated Delta Z value. This
option is very useful in correcting point elevations after performing a
survey with assumed elevations and then later surveying into a
benchmark with known true elevation. In this case only the Delta
Z value, use (-) to indicate a lower correction, and the range of
points to translate would be required for a translation. For
example if the entire job needed to be lowered by 5', the Delta Z would
be defined as -5 and the Range of Points defined as ALL.
Ignore Zero
Elevations is only available when Process
Elevations has been chosen. With this option checked ON, all
points with an elevation of 0 will be ignored resulting in no
translation taking place on these points.
With Translate
Screen Entities
checked ON, after specifying the point range or group to translate and
selecting OK on the dialog box the following command line prompt is
displayed:
Select objects to rotate (points excluded):
At this
prompt select the objects on the screen, polylines, lines, arc, etc.,
to
also translate and press enter. The translation of the points and
screen entities will be completed.
Various Output Options for the translated points are available.
Overwrite Existing Coordinates will overwrite the existing coordinate points with the new translation coordinates thus changing the coordinate values in the existing crd file.
New Point Numbers will assign new point numbers to the translated coordinate points and leave the original coordinate points unchanged and present in the coordinate file. When using this option, on the Range of Points to Translate dialog, there is a Value to add to point numbers field. In this field, enter the value to add to the point numbers. For example if the existing point numbers are 1-20, and the value to add is 100, the resulting new point numbers will begin at 101 and end at 120.
New CRD File
will place the translated coordinates in a new crd
file. After selecting OK to
the range of points to translate dialog, the Coordinate File to Create
dialog will appear. On this
dialog enter the name of the new crd file and select save. The original
crd file will remain unchanged
and the new file will contain the points with the translated
coordinates.
Specifying the points to be translated is accomplished either by
specifying a Range
of Points (1-20,33,36-40....) or by Point
Groups. If using the Point Group option, the Select Point
Group(s) dialog box will be displayed allowing for the selection of the
Group(s) to rotate.
The Description Match
option only translates points with the description(s) specified in this
field.
Undo Last Translation restores the points to their previous location before translation. It is important to note that if Translate Screen Entities has been checked to restore the translated objects to their previous location will require the use of the undo command located in the Edit pulldown.
The AutoCAD command MOVE can be used to translate points on the screen but this does not update the coordinate file unless you have the option Link Points with CRD File turned ON in Configure . (Note: This toggle must have been turned ON prior to locating the points). If you do use the MOVE command and the CRD file needs updating, run the command Update CRD file From Drawing found in Coordinate File Utilities.
