Creating standard cross-sections

Tool(s): Entering cross-sections in the bridge and civil engineering modeler

1. Select one of the following options on the cross-section toolbar or Edit menu:
   • Add Girder
   • Add Triangle
   • Add Rectangle
   • Add Regular Trapezium
   • Add Irregular Trapezium
   • Add Irregular Polygon
2. Enter the geometric dimensions and the position of the reference point of the cross-section in the unit of length and unit of angle set and specify whether the area is to be created or added or whether it is to cut out an existing area.

   Note: Using Add Irregular Polygon, you can also create ellipses as cross-sections. All you have to do is enter the double radii and an angle of rotation.

3. Click OK to confirm the dialog box.

   Allplan calculates the coordinates of the polygon points.

4. Edit the cross-section created or quit definition to assign the cross-section to the current station point.
   

Tip: When you right-click in the graphics area and select a default cross-section, the coordinates of the point clicked are automatically copied and proposed for the reference point.

Note: You can also delete a cross-section while entering it.

Deleting cross-section while entering it

If you have deleted a region of a cross-section by entering another cross-section, you can restore the original state by adding the same cross-section. You can use the shortcut menu; the point clicked is automatically used as the reference point.

If you want to discard an entire cross-section, you can add a new cross-section which covers the original cross-section in its entirety or you can remove a rectangular cross-section which covers the existing cross-section in its entirety by selecting the Delete option.

Deleting cross-section after having entered it

To delete an entire cross-section, you can use Delete All Corner Points. However, partial cross-sections you have added later are not deleted. These can be removed using Delete Addition to Cross-Section.
