Show/Edit Polyline

Use the following procedure to view or edit the data attached to a polyline (bridge cross-section polyline or road surface polyline).

Note: The polyline (bridge cross-section or road surface polyline), which is to be edited should be available on AutoCAD drawing to select while operating this tool. If the polyline, which is to be edited, is not available on AutoCAD drawing, draw it using the tool 'Draw Cross Section'.

Note: Activate the side screen menu of AutoCAD if it is turned off. Run the function Options (of AutoCAD) and click the tab Display, activate Display screen menu.

Find the function here:

Ribbon: Bridge > Inspect Polyline > Show/Edit Polyline

Command prompts for:

1. Select a polyline:

2. Select the bridge cross-section, which is to be edited.

3. A crossmarks on the first point of the polyline will be displayed. Data for the highlighted point (point with the cross mark) is shown on the side screen menu. Options to edit the data will be on the command prompt.

4. Next/Previous/Edit/Move/Insert/eRase <X>: You can use these commands for editing a polyline. It is sufficient to enter the capital letter of each choice. Point numbers for the current points will always be shown on the screen menu. The selected point will also be shown as a white cross mark on the AutoCAD screen.

• Next/Previous - Use the option Next/Previous to traverse along the points of the selected polyline.

• Edit - Use the option 'Edit' to change the point type (connection type) for the point marked with a white cross mark. For detailed information on point type and respective connection mechanism see the topic 'Point Type and Connection Mechanism'. You will get the same questions when you register a polyline, but the questions, in this case, only apply to a selected single point (point marked with the white cross mark).

• Move - Use the option 'Move' to move the highlighted point (point with the cross mark). This command works in the same way as the move command in AutoCAD, but you can only move a selected single point at a time (point marked with the white cross mark).

• Insert - Use the option 'Insert' to add a new point to the selected point type.

• eRase - Use the option 'Erase' to delete selected point (point with the cross mark).

• X - To exit the tool, use the option 'X' or the key ESC.

In the screen menu on the right-hand side of the drawing area, a list of data concerning the entity and the points of the selected polyline will appear. The information about the station number for the cross-section, the polyline number (entity number defined while register), point number and point type is the same for all points. The information regarding reference points will vary. For point types 1, 2, and 3, these points will be surface numbers of the road. For point types 4 and 5 these points will be structure points. For detailed information on point type and respective connection mechanism see the topic 'Point Type and Connection Mechanism'

If you select a road line to edit, you will get information about station numbers and road surface numbers.
