Quick Section – Cross Section and Longitudinal Section Software

Quick Sections is a compact and powerful utility to generate sections instantly within the CAD from data available within CAD or from a CSV file. Generate Area and Volume reports depending on cross section data.

With E Quick Sections you can

1. Draw lines representing sections and rebuild the section with detailing
2. Generate Cross Section drawings by referring to spot levels representing Cross sections along an alignment
3. Generate Longitudinal section drawing by referring to spot levels representing the Longitudinal Section
4. Convert 3d Polyline as a section
5. Modify a generated LS & CS and export the modified values back as spot levels.
6. Create cross section and Longitudinal section from CSV
7. Interpolate section data while creating sections
8. Insert Blocks in each cross section referring to FRL from Longitudinal Section line
9. Export section data to excel
10. Generate Area and Volume Report

Getting Started

Before we start using Quick section we have to understand some concepts and also we need to know layer specifications as required by Quick Section.

Layer Specification

Before exporting spot levels along an alignment, Lines representing Cross Sections have to be necessarily be present in CS Layer

The line representing a centre line or alignment needs to be present in LS Layer

All the spot levels that will be considered for section generation need to be in Layer 1 to Layer 5

ESurvey Quick Section
Lines representing series values of a cross section or longitudinal Sections also need to be in Layer 1 to Layer 5

ESurvey Quick Section
Section Setting

Sections that get created from software will depend on the settings that you make. I.e, Layer Name (Ground Levels, Formation Levels), Projection line, Interpolation, Drawing Scale and Footer caption definition, requirement has to be set before drawing any section and we can change all the settings using Modify Sections Setting (MSS) option from the “Quick Section” menu.

Marking Chainages and Interpolating data along the alignment

Now look at marking the chainages along a longitudinal section line. 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 labeling like “Chainage at 30 M”. This labeling includes prefix, suffix, decimal precision of the chainage, increment, cross section line length and the change points, which represent the change in the path or direction of the alignment.


ESurvey Quick Section

Alignments are drawn in CAD with a polyline and perpendicular lines are drawn at regular intervals representing the cross sections. Sometimes these lines are required at change points which are the vertices of the polyline representing the alignment.

ESurvey Quick Section
Marking each cross section line along an alignment with proper labeling will make the drawing more readable. Marking these cross section lines and labeling them in CAD takes a lot a time. Whereas using the MCH command, marking cross section lines along with the labels is done in one step.

ESurvey Quick Section

1. Draw lines representing sections and rebuild the section with detailing

Quick section can create cross sections just by referring to polylines representing series values in any horizontal and vertical scale. We will create one cross section by just drawings 3 polyline to understand the concept.

Section Object
Quick section uses an attribute block which is referred as “Section Object” which will have Section Number, Horizontal Scale, Vertical Scale, Datum value and chainage at the insertion of the attribute block as its values. Select “Insert Section Object (IS)” from “Settings and Section Object” sub menu and create a section object with the values given below.

a) Section Number: 100
b) Horizontal Scale: 200
c) Vertical Scale: 50
d) Datum Value: 95
e) Chainage at the insertion point of attribute : 0

ESurvey Quick Section
Attaching line to Section Object You draw three Polylines representing series values. Put them in Layer1, Layer2 and Layer 3.

[Insert image which are just polyline before creating the cross section] ESurvey Quick Section


Now you have to create relationships between section object and these lines. Select “Attach line to Section Object (ATTLI)” option from “Settings and Section Object” submenu and select the section object and these lines. Now section object is linked to these lines. Now select “Recreate / Export Section by selecting a Section object (EXCQ)” from “Export and Reports” sub menu ESurvey Quick Section
The command will prompt you asking “Do you want to create a section?”. Say yes and pick a point to place the cross section. You may note that in output cross sections, all the cross section values are derived and are represented in respective series bands.

2. Generate Cross Section drawings by referring to spot levels representing Cross sections along an alignment

Sections can also be created from data available in CAD along an alignment. Please note that you need to have the spot levels data in Layer 1 to Layer 5 along the alignment as shown.

ESurvey Quick Section
If you have raw survey data, then you may use ‘Interpolate’ module of ESurvey CADD ESurvey Interpolate version to interpolate the value along an alignment. Also note that you can use ‘MCH’ command to mark the Cross section lines along the alignment. Once you have the data arranged along the alignment as shown in the drawing you can create sections. To create cross sections, Select “Create cross sections by selecting alignment data (CAQ)” from the Cross Section Submenu. ESurvey Quick Section
Next type the box width, which is an approximate width to select spot levels.

ESurvey Quick Section

Then select all the cross section lines, after which, a box is drawn around each cross section line and also the number of texts which will be exported will be displayed.

Now pick a point and you can see that the cross sections are generated.

ESurvey Quick Section
You can also create respective Longitudinal Section. Select “Create LS by Selecting CS Values (CLS)” menu item from Cross section submenu and pick a point to place the longitudinal section. Quick Section will create cross section by selecting the spot levels at 0 distances of each chainage.

3. Generate Longitudinal section drawing by referring to spot levels representing the Longitudinal Section

This option is used to create a longitudinal section based on the elevation texts in the drawing. To create a longitudinal section file, select “Create section by selecting a single line (CQS)” from “Quick Sections” menu. Select a polyline. Enter the Section identification number. Select Elevations, using which Section has to be generated. Pick a Point to place the generated section. As per the settings set through ‘MSS’ Command cross section will be created.

ESurvey Quick Section
4. Convert 3d Polyline as a section

You can create a Section by selecting any 3d line in the drawing and specifying respective section identification number.

5. Modify a generated LS & CS and export the modified values back as spot levels.

Please note that when the section is generated using Quick section, one attribute is also getting created along with the section. This attribute is important while posting back the data along the alignment. To post back the values first of all we have to explode the section that is created. Then, if you look closely all the lines representing the section are made up of lines. We can join them by running command ‘PJ’ from an E Quick Section menu. Now we can modify the polyline as per our choice. Once the section lines are modified, you need to attach these lines to the respective attribute (which is referred as Section object in Quick Section) using ‘Attli’ command.

ESurvey Quick Section
Let us delete the spot levels for respective cross section as new values have to be placed. Now you need to select the “Post back value of a section by selecting the CS line (PBCS)” from EQuick Section menu and select the line representing the alignment and section object. As you can see all the cross section levels are ported back along the respective cross section line.

[Below Image is wrong, even with Zoom Glass, one cannot make out what is in posted back value]

6. Create cross section and Longitudinal section from CSV

You can easily create cross sections from Excel or CSV data. If you have data for cross section in Excel or CSV, put it in the first four columns – Layer Number, Section Number, Distance, Elevation Value as save the file in Temporary Directory (C:\ESurvey\Temp) with file name Quick.

ESurvey Quick Section
Select “Create CS by reading CSV Values (SCSV)” option from the Cross Section submenu.

ESurvey Quick Section
You will be prompted to pick a point to place the cross sections. Quick section will create all the cross sections from CSV Data.

7. Interpolate section data while creating sections

You can create cross sections in many ways. Either from CAD data or from CSV as explained earlier. If you want to interpolate the values along the cross section when creating cross section, you can do the same using MSS Command.
ESurvey Quick Section

ESurvey Quick Section
Let us say in your input data, you have data scattered at different distance. Say 1.63 M, 4.52, 6.71. But you wish to interpolate the levels at each meter distance. In such cases, select “at interval” and specify “1” as the value and save the setting. Enable “Interpolate” check box for layer corresponding to spot level layer. Say your spot levels are in Layer 1 then you enable interpolate option for Layer1.

ESurvey Quick Section
When you create the cross sections, you may note that input values are interpolated along the cross section.

8. Insert Blocks in each cross section referring to FRL from Longitudinal Section line.

Cross sections in Quick Section gets created using ground data along the alignment. To find out the area and quantity, you need to create formation levels. This is done by defining a cross section template and then inserting it at formation level of each cross section.

ESurvey Quick Section
After inserting the template, trim the lines which need to stop at intersection.

ESurvey Quick Section
If you have ground data in Layer 1 and If the template line is in Layer 2, then you can attach these 2 lines to respective Section Object and you care recreate the section to get the area calculation. Inserting these blocks at formation level of each cross section is automated with IBFL (Insert blocks at the cross section referring Formation Level) command. Select “Insert blocks at the cross section referring Formation Level (IBFL)” by selecting “longitudinal section” sub menu.

ESurvey Quick Section
Before using this command, create the longitudinal section and draw formation level series line in CAD Package. Or if you have the data in excel, convert it as Quick.CSV file and save it in a temporary folder (C:\ESurvey\Temp). Create the longitudinal section by using SCSV command as explained above.

ESurvey Quick Section
You also need to create a CAD Block of your Template representation to insert it in cross section. It is recommended to have the cross section template line in Layer 2. When you execute IBFL command, you will be prompted to provide horizontal scale, vertical scale, starting chainage of CS and a reference point. After providing this information, select the series line representing the longitudinal section from section drawing. Then command will prompt you to specify the block name, mention the block name which has cross section template and select the section objects of cross sections for which you want to insert the template. IBFL command will insert the block at formation level by reading the content of each section object.

ESurvey Quick Section
You can now trim extended formation lines. Once you have prepared all the individual cross section you have to attach formation level to section object. Use ATML (attach multiple line to section object) command to attach lines to all the selected section objects in one go. Use “EXCQ” command to recreate the cross sections so that formation layer series values will also be updated in cross section.
