Menu: Convert Connected lines to Polyline (PJ)Functionality: To join adjoining line / arc / polylines to make a single Polyline entity.
Description: A polyline is a connected sequence of lines and arc segments created as a single object. Editing becomes easy if broken lines with common endpoints are connected as a single polyline. This can be done manually in CAD using the PEDIT command which involves multiple steps. Also ‘PEDIT’ command allows joining one set of lines at a time. Using PJ command multiple sets of connected lines can be converted to polylines in just one step.Procedure:
Menu: Reverse the Polyline (RPL)Functionality: To redraw the polyline in a reverse direction.
Description: Any polyline will have two ends, starting point to ending point. Any program which measures a polyline reads the distance from the start point of the polyline. The start point of a polyline can be viewed with the help of PEDIT command in CAD. So, if a polyline is drawn in reverse direction then the chainages marked along the alignment will be wrong. To overcome this, normal practice is to recreate the polyline once again in the correct direction, but this method takes time. RPL command reverses the polyline without a need to redraw the polyline manually.Procedure:
Menu: Mark Chainages along an Alignment (MCH)Functionality: To mark chainages along a polyline with a given interval.
Description: An alignment represents the path where perpendicular lines along the alignment indicate cross sections. It is a practice to mark each cross section line with proper labelling like “Chainage at 30 M”. This labelling includes prefix, suffix, decimal precision of the chainage, increment, cross section line length and the change points, which represent the change in path or direction of the alignment. Marking each cross section line along an alignment with proper labelling will make the drawing more readable. Marking these cross sections lines and labelling them in CAD takes a lot a time. Whereas using the MCH command, marking cross section lines along with alignment line is done in one step.Procedure:
Menu: Measure each Segment of Polyline (MSE)Functionality: To measure individual segments of a polyline.
Description: Many times each line segment of the boundary or alignment is to be labelled with the distance between their respective vertices i.e. the length of the individual line segments to be labelled. Manually labelling individual segment of the polyline in CAD takes a lot of time. By using ‘MSE’ command, any number of segments in a polyline can be labelled with their length.Procedure:
Menu: Measure Cumulative Distance along a Polyline (MCD)Functionality: To measure the cumulative distance at each segment along the polyline.
Description: Cumulative distance is the increasing distance got by successive addition. Using ‘MCD’ command cumulative distance of each segment along a polyline can be measured easily. The cumulative distance is measured starting from the first vertex and then along the polyline. The label indicating distance on the last segment of the polyline line gives the Total length of the polyline.Procedure:
Menu: Mark Each Node (MEN)Functionality:F To mark the text with the selected prefix at each node of the polyline.
Description: Using ‘MEN’ command, each vertex of the polyline can be labelled.Procedure:
Menu: Measure Clockwise Bearing (BCW)Functionality: To find out the bearing in an anticlockwise direction.
Description: Bearing is an angle measured from the North terminus of a reference meridian. The BCW command can be used to get the clockwise bearing of a selected boundary. The boundary is labelled and also a summary for the selected boundary is displayed which comprises of the bearing name, distance, easting, and the northing value. These values are also exported as a file ‘Bearing.CSV’ in temporary directory (C:\ESurvey\Temp\Bearing.CSV).Procedure:
Menu: Measure Anti-clockwise Bearing (BAW)Functionality: To find out the bearing in the anti-clockwise direction.
Description: Bearing is an angle measured from the north terminus of a reference meridian. The 'BAW' command can be used to get the anti-clockwise bearing of a selected boundary. The boundary is labelled and also bearing summary for the selected boundary is displayed. The summary comprises of the bearing name, distance, easting and northing values. These values can be displayed anywhere at the selected pointed in CAD. Also, a CSV file of the bearing report is generated in a temporary directory (C:\ESurvey\Temp) directory.Procedure:
Menu: Find Total length of selected Lines (ETE)Functionality: To find the total length of selected Lines.
Description: While working on survey drawings many times there will be a requirement to find the total length of the selected polylines. For example, when you are working on a town map, to find the total length of roads in a particular layout, you can find the total length of all the road
For example, when you are working on a town map, to find the total length of roads in a particular layout, you can find the total length of all the road centre lines. By doing this you come to know the total road length of the layout. Using ‘ETE’ command you can find out the total length of selected polylines easily. And also the individual polyline lengths, marked with node points are exported to a CSV file in a Temporary directory (C:\ESurvey\Temp) directory.
Menu: Indicate Polyline Direction (PLD)Functionality: To quickly show the direction of a polyline
Description: In CAD, when there is a polyline drawn, you cannot visually make out in which direction the polyline was drawn. Say, it is from right to left or left to right. This can be found out with ‘PEDIT’ command indirectly. When you jump from one vertex to next vertex within ‘PEDIT’ command you can make out the direction of the polyline. To make this process simple ‘PLD’ command has been developed.Procedure:
