Draw Building Section
Draw Building Section tool displays a cross section of a building. The tool is intended to be used, for example, before Extrude Building tool. It provides a cross section view of the laser data that is suited for drawing a building roof profile line. In addition, the tool can be helpful in cases there are no image available for modifying vector models manually. Then, it speeds up the drawing of sections for single building planes.
To draw a building section:
1. Load point cloud data into TerraScan.
2. (Optional) Open one or two additional CAD file view(s) that can be used for the section display.
3. (Optional) Draw a fence around the area from which you want to create a cross section.
4. Select Draw Building Section tool.
The Draw Building Section dialog opens:
5. Select an option for the tool setting.
6. If Fit to show is set to Single patch, move the mouse pointer in the top view. If the mouse point is inside a patch, it is highlighted. Define the patch with a data click in the top view.
7. Define a view with a data click.
This displays the building or patch section in the selected view.
8. If Fit to show is set to Single patch, define the second view with a data click.
This displays the second patch section in the selected view.
