Road Points

This dialog displays stations, transition points (start and end points of all elements in horizontal and vertical alignments) and height extremums of the selected road.

Start Sta - the start station of the road
End Sta - the end station of the road
Sta - the station of the road
Hz Line EP - the end point of the straight line of the horizontal alignment
Hz Arc EP - the end point of the left circular curve of the horizontal alignment
Hz Arc EP - the end point of the right circular curve of the horizontal alignment
Hz Spiral EP - the end point of the left spiral of the horizontal alignment
Hz Spiral EP - the end point of the right spiral of the horizontal alignment
Hz Arc MP - the middle point of the circular curve of the horizontal alignment
Vt Line EP - the end point of the grade of the vertical alignment
Vt Parabola EP - the end point of the parabola of the vertical alignment
Vt Arc EP - the end point of the arc of the vertical alignment
Vt High Pt / Vt Low Pt - the high / low extremes on crest / sag sections of the vertical alignment

The table displays a station and coordinates of each point in the current coordinate system. Click to close the map view and to show the table on the full screen. Click to divide the dialog into two parts: table view and map view.

The map view displays the selected point (in the table) at the road central line in the horizontal and vertical planes.

Click the Filter button to open the Filter Road Points dialog, where you can select the different types of the road points to show them in the Road Point dialog. If the check box on the Filter button is unchecked (), all types of road points will be shown in the table. If the check box on the Filter button is checked (), selected types of road points will be shown in the table.

If the horizontal alignment contains Intersection Point (IP) element(s), you can view the number of the IP element in the vertical profile and identify the part of the compound curve to which the road point belongs. To do this, select the Show IP Numbers option from the dialog menu that opens by clicking in the top left corner. This number will be shown in the Type column of the table:
