Use dynamic quick sections as a tool to quickly view the terrain in a particular area. Dynamic sections can be copied and pasted into any Windowsâ application, or imported into the drawing using the current drawing scale.
You can create quick sections from one or multiple surfaces. Multiple surfaces are currently turned on in the project, so the quick section you create in this task will be based on the surfaces EG and FG, the two surfaces you selected previously with the Define Multiple Surfaces command.
Zoom to the previous view.
From the Terrain menu, click Sections
View Quick Section.Select the section line C-C in the drawing, and then press ENTER to display the Section window.
The Section window can be moved and resized in the drawing. You can also change the section properties using the Section pull-down menu in the upper left corner of the Section window.
Use the following steps to change the vertical scale of the section.
From the Section menu in the Section window, select View Properties to display the Quick Section Properties dialog box.
On the Grid Settings tab enter 2 for Vertical factor, enter 10 for the Minimum Vertical Increment, and enter 50 for the Minimum Horizontal Increment.
Click the Surface Color Settings tab. Note that the color of EG is green and the color of FG is blue. You can change the colors of up to 8 surfaces when viewing quick sections for multiple surfaces.
Click OK.
You can grip edit the line from which you created the section, and the view in the Section window is updated dynamically.
Select section line C-C in the drawing to display its grips, and then select one of the grips and drag it to a new position.
Observe that the section view is automatically updated to reflect the new position of the section line.
You can import a quick section into the drawing using the current drawing scale.
From the Utilities menu in the Section window, select Import Quick Section.
Type tutorial1 as the layer name prefix for the surfaces.
When you import the quick section, the section line for each surface is placed on a unique layer. By using tutoral1 as the prefix, the section line for surface EG will be created on layer tutorial1-EG, for example.
Press ENTER to accept the default, datum, as the datum line layer.
Type CC as the description for the section.
Enter 2 for the Vertical scale factor.
Select an insertion point for the section below the section CC you imported earlier.
Press ENTER to accept the default datum elevation.
The quick section is imported into the drawing.
Close the section window so you can see the imported quick section.
This concludes the section creation lesson. In the next lesson, you'll learn about surface visualization tools.
