(command "_layer" "make" "dim" "" Make the layer (setq la (getvar "CLAYER") Save current layer Select Entities: Select lines whose total length is to be found.Code: Save and get information from user And also the individual polyline lengths, marked with node points are exported to a CSV file in a Temporary directory (C:\ESurvey\Temp) directory.Ģ. Using the ‘ETE’ command you can find out the total length of selected polylines easily. By doing this you come to know the total road length of the layout. 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 roadįor 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. Menu: Find Total length of selected Lines (ETE)įunctionality: To find the total length of the selected Lines.ĭescription: While working on survey drawings many times there will be a requirement to find the total length of the selected polylines. FIND TOTAL LENGTH OF SELECTED LINES (ETE) Select the Chainage Line (L Section Line): Enter the length of the L section line.ĩ. Change Points to be Included? Y / : Select Y to include change points.ĩ. Type the Increment : Enter the value to be incremented for every chainage.Ĩ. Type the Starting Chainage : Type the starting chainage value.ħ. How far the Chainage Text to be from Line : Enter the distance between the chainage text and line.Ħ. Type the Precision: : Enter the number of decimal places for the chainage value.ĥ. Type the Suffix : Enter the string that is to be added after the chainage text.Ĥ. Type the Prefix : Enter the string that is to be added before the chainage text.ģ. Whereas using the MCH command, marking cross-section lines along with the alignment line is done in one step.Ģ. Marking these cross-sections lines and labelling them in CAD takes a lot of time. Marking each cross-section line along an alignment with proper labelling will make the drawing more readable. 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. It is a practice to mark each cross-section line with proper labelling like “Chainage at 30 M”. Menu: Mark Chainages along an Alignment (MCH)įunctionality: To mark chainages along a polyline with a given interval.ĭescription: An alignment represents the path where perpendicular lines along the alignment indicate cross-sections. Select Objects: Select the line/arc or polylines that are to be connected together to make a single polyline.ģ. Using the PJ command multiple sets of connected lines can be converted to polylines in just one step.Ģ. Also ‘PEDIT’ command allows joining one set of lines at a time.

This can be done manually in CAD using the PEDIT command which involves multiple steps. Editing becomes easy if broken lines with common endpoints are connected as a single polyline.
