Using contour module we can easily draw section profile within the CAD drawing and export the section data to excel.It involves 3 steps.
Type the interval at which you need to interpolate the value for section generation, closer the interval you will get the accurate profile. Also, the program will ask you Change Points to be Included ? Y / N.Select Yes if you require elevations to be interpolated at the end point of each polyline segment.
Now select the polyline representing the alignment. 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 you have done in step 1.Note: 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'.
