Longitudinal Section on Contour Surface

Draw Longitudinal Section of any Alignment on Contour Surface using the Contour Module of ESurvey CADD. You can specify the Chainage Interval, Section Scale before generating the Longitudinal Section of the alignment. A Longitudinal Section will be generated within AutoCAD once you select the alignment line for which you want to generate the profile at a specified Scale factor.

Draw Section for an Alignment within CAD
Hello everyone, welcome to a video tutorial about drawing a Section representing Profile along an alignment on a Contour Map using ESurvey CADD Contour Module.
Using the contour module we can easily draw section profile within the CAD drawing and export the section data to excel.
It involves 3 steps.
a. Setting the Section Parameters
b. Creating the Section (Profile)
c. Exporting the data to Excel
Select Section setting option from ESurveyCAD menu:
Set the horizontal scale, vertical scale, Footer prefix, footer suffix, the caption for Section data reference, select the projection line and set the datum precision.
You may create the Alignment just by drawing a Pline on the CAD drawing. Please note that all the elevations should be available in the layer named ‘ELEV’.

Now, to draw a section line select draw section option from ESurvey CADD menu under Contour Sub Menu, type the interval at which you need to interpolate the value for section generation, closer the interval you will get an accurate profile. Also, the program will ask you ‘Do you want to include the change Point’ select ‘Yes’ if you require elevations to be interpolated at the endpoint of each polyline segment. Now select the Polyline representing the alignment. All the values will be interpolated along the alignment at a specified interval and the interpolated values will be created on a layer called ‘Layer 1’. If the alignment is outside the boundary then also levels are interpolated which may not be mathematically accurate and hence such levels are created in ‘Layer 2’. The program will prompt to click a point for placing the section in the drawing, using all these interpolated levels a section would be created as per the settings we have done in step 1.
If required, these section levels can be exported to excel using option export section levels to excel from an E Survey CADD menu.

Thanks for watching this video, In the next video you will learn how to further Annotate Contours.
