Menu: Draw grid with given grid interval (DGRID).Functionality: To draw the grid with given grid interval.
Description: A grid is a pattern of parallel lines intersecting at right angles and forming squares or rectangles. It is used to identify precise positions, to help you locate a position accurately on the surface of the earth or map sheet. Using ‘DGRID’ command, grid lines can be drawn easily at any required interval. ‘DGRID’ will also annotate all the grid lines with respect to its Easting and northing.Procedure:
Menu: Snap text to nearest point on the grid with the given grid spacing (SNP)
Menu: Lat Long of a selected Point (FLL)Functionality: To show the Lat Long of a selected Point. You need to set the datum, hemisphere and zone before selecting the point.
Description: Survey drawings are represented with coordinate system. Our globe is spherical and it is more precise when represented with Latitude and Longitude. To find out the Lat / Long of a given co-ordinate ‘FLL’ command can be used. You need to set Datum, hemisphere and Zone of the drawing to find the Lat / Long.Procedure:
Menu: Put Box around Text (BXT)Functionality: To put box around text.
Description: This option is used to put box around selected texts.Procedure:
Menu: Traverse Correction (TC)Functionality: To correct the traverse and give details of calculation.
Description: Description about traverse correction can be found in Interface chapterProcedure:
Menu: Paste Clean Text (PCT)Functionality: To create new set of elevations ensuring maximum of only one level at a given point.
Description: When point data is collected from various total stations, it may so happen that at same easting and northing there may be two or more elevations. Using such overlapping data if you try to triangulate or generate contours then triangulation may not be possible as there will be multiple levels in same easting and northing and the program will not be able to make out which data to be used. For that reason, you need to process the data and clear extra point at a specific x, y. Using PCT command you can clear extra points and paste clean text.Procedure:
Menu: Sea-level type Elevation Representation of Text and Block (SEA)Functionality: To represent Sea-level type Elevation representation for Text and Block.
Description: Representation of Survey data on ground and in Sea differs. We represent elevations as 134.56 in ground where as same data say -3.45 (Elevation in Sea) then it is represented as -3 and 45 as two different text. Using ‘SEA’ command normal elevations can be converted as labels which represent sea level.Procedure:
