Moving Horizontal Alignment

The horizontal geometry table (tab Input H or the Horizontal Design Line) must be active to move the horizontal alignment.

Moving the horizontal alignment will affect the longitudinal terrain profile the vertical alignment was designed against.

When moving the horizontal alignment the vertical alignment will stay unchanged as much as possible. That means the North and East position of the vertical intersection points will be displaced parallel to the original position. Small moves of the horizontal will then not make any big influence of the vertical alignment.

MOUS_ICO Menu: Modify > Get Fixed Points from Result

Tip: This function can also be activated from the shortcut menu of the main dialog Alignment Design. To activate the function from the main dialog, activate the alignment geometry table (Input H or Input V), select multiple element rows or at least two element rows, place the cursor on the selected rows, activate the shortcut menu, and select the menu option Get Fixed Points from Results.

Calculate Angular Points

Methods to relocate/edit the coordinates of/move the angular point(s) to modify the alignment are:

1. Drag and drop the angular point(s) in graphical display.

2. Pick an existing point from the graphic display and its coordinates will be applied to the active angular point.

3. Key-in the desired coordinates for the desired angular point in the user-interface (using this function).

4. Key-in the desired coordinates for the active angular point form the command line.

One of the methods to modify the alignment is relocating (editing the coordinates of) the angular point(s) in the user-interface. Relocating the angular point(s) changes the length of the alignment elements (line and arc) but not the radius of the arc element.

Do the following to change the angular point(s) of the horizontal alignment from the user-interface:

• Activate the table Input H of the user-interface.

• Run the function Calculate Angular Points.

• Edit the coordinates of the angular point(s) (E1 and N1) directly in the cells of columns E1 and N1 of the user-interface.

Do the following to change the angular point(s) of the vertical alignment from the user-interface:

• Activate the table Input V of the user-interface.

• Run the function Calculate Angular Points.

• Edit the coordinates of the angular point(s) (Chainage1 and Level1) directly in the cells of columns Chainage1 and Level1 of the user-interface.

Run the function from the following locations in the user-interface Alignment Design:

MOUS_ICO Toolbar: Calculate Angular Points

MOUS_ICO Menu: Modify > Calculate Angular Points

Tips: This function can also be activated from:

   • To active the function from the shortcut menu of the user-interface, activate the alignment geometry table (Input H or Input V).

   • Place the cursor anywhere in the table.

   • Activate the shortcut menu, and select the menu option Calculate Angular Points.

2. The shortcut menu of the design line (horizontal or vertical alignment):

   • To activate the function from the shortcut menu of the design line (horizontal or vertical alignment), pick the alignment with the left button of the mouse.

   • Place the cursor on any element of the alignment.

   • Activate the shortcut menu, and select the menu option Calculate Angular Points.

This function calculates the angular points of the active alignment.

• In order to view the result of this function it is recommended to turn on the Grips of the design line. The grips can be turned On/Off with the function Display. Though the grips are turned off, the function works but to see the results select the design line (horizontal or vertical alignment).

• Angular points for all the curves of the active alignment will be calculated by this function, provided the curves element type must be approximate and the adjoining straight line elements must be of type fixed (with two fixed points). The fixed points are placed on top of one-another, to allow them to be moved simultaneously.

Example

Situation after calculating angular points:

To switch back to the previous type of representation, run the function Split Angular Points (see below).

Split Angular Points

Methods to relocate/edit the coordinates of/move the fixed point(s) to modify the alignment are:

1. Drag and drop the fixed point(s) in graphical display.

2. Pick an existing point from the graphic display and its coordinates will be applied to the active fixed point.

3. Key-in the desired coordinates for the desired fixed point in the user-interface (using this function).

4. Key-in the desired coordinates for the active fixed point form the command line.

One of the methods to modify the alignment is relocating (editing the coordinates of) the fixed point(s) in the user-interface. Relocating the fixed point(s) changes the length of the alignment elements (line and arc) but not the radius of the arc element.

Do the following to change the fixed point(s) of the horizontal alignment from the user-interface:

• Activate the table Input H of the user-interface.

• Run the function Split Angular Points.

• Edit the coordinates of the fixed point(s) (E1, E2, N1, and N2) directly in the cells of columns E1, E2, N1, and N2 of the user-interface.

Do the following to change the fixed point(s) of the vertical alignment from the user-interface:

• Activate the table Input V of the user-interface.

• Run the function Split Angular Points.

• Edit the coordinates of the angular point(s) (Chainage1, Chainage2, Level1, and Level2) directly in the cells of columns Chainage1, Level1, Chainage2, and Level2 of the user-interface.

Run the function from the following locations in the user-interface Alignment Design:

MOUS_ICO Toolbar: Split Angular Points

MOUS_ICO Menu: Modify > Split Angular Points

Tip: This function can also be activated from:

1. The shortcut menu of the user-interface Alignment Design:

   • To active the function from the shortcut menu of the user-interface, activate the alignment geometry table (Input H or Input V).

   • Place the cursor anywhere in the table.

   • Activate the shortcut menu, and select the menu option Split Angular Points.

2. The shortcut menu of the design line (horizontal or vertical alignment):

   • To activate the function from the shortcut menu of the design line (horizontal or vertical alignment), pick the alignment with the left button of the mouse.

   • Place the cursor on any element of the alignment.

   • Activate the shortcut menu, and select the menu option Split Angular Points.

This function split the angular points of the active alignment, which were calculated with the function Calculate Angular Points (see above) and the fixed points are moved to the ends of the line elements.

• In order to view the result of this function it is recommended to turn on the Grips of the design line. The grips can be turned On/Off with the function Display. Though the grips are turned off, the function works but to see the results select the design line (horizontal or vertical alignment).

Example

Situation after splitting the angular points:

To switch back to the previous type of representation, run the function Calculate Angular Points.

Connect

Use this function to connect the following elements that are already drawn on the current drawing.

• CAD elements (polylines, lines and arcs).

• Novapoint object (such horizontal alignment, etc).

• Even construction lines of other active alignment design can be connected (only in horizontal).

The following types of connection can be done with this function:

1. Connect: Simply connecting the elements, which are selected from CAD.

2. Add Arc and Connect: The command sequence will be the same as above, but a curve element will be added by the program which will the connecting element between the active alignment and the selected elements.

3. Add Line and Connect: The command sequence will be the same as above, but a line element will be added by the program which will be the connecting element between the active alignment and the selected elements.

4. Add Transition Curve(s) and Connects: The command sequence will be the same as above, but Novapoint will add a transition curve element, which will be the connecting element between the active alignment and the selected elements.

As there are no transition curves for vertical alignment, the connections with transition elements of the above are not available when the function Connect is activated on vertical geometry.

Run the function from the following locations in the user-interface Alignment Design:

MOUS_ICO Toolbar: Connect

MOUS_ICO Menu: Modify > Connect

Command prompts for:

Pick a line, arc, polyline:

Select the elements which are to be connected to the active alignment.

The selected elements are connected next to the last element of the active alignment. If the selected elements are to be connected at the start of the alignment, the alignment's direction is to be turned before activating the function Connect. The direction of the element can also be reversed with the function Turn.

Tip: It is recommended that the end of the first alignment and the start of the second alignment is in the same horizontal point, and that the vertical design goes all the way to this chainage. For best results the alignment should have a straight line in the connection point in both horizontal and vertical to handle any deflections in the design between the two lines. If straight lines are not made in the connection points the connections might fail to connect properly without user interaction with regards to for example fixation logics or two consecutive curves with same radius and direction.

Append Combination

Use these functions to add multiple elements with specified combination.

• There are a number of combinations which can be added to the alignment.

• These combined elements will be added next to the last element of the alignment, irrespective of the element, which is active (highlighted) in the main dialog box or the graphic alignment.

• The following are the combinations, which can be added with this function. In the following text, the phrase "Curve direction turned" means that the direction of the curve element that is added will be opposite to that of the previous curve element of the alignment. The program assumes that there is right-left-right kind of formation of alignment.

As there are no transition curves for vertical alignment, the combinations with transition elements of the above are not available when this function is activated on vertical geometry.

Run the function from the following locations in the user-interface Alignment Design:

MOUS_ICO Menu: Modify > Append Combination

Tips: This function can also be activated from the shortcut menu of the main dialog Alignment Design or from the shortcut menu of the design line (horizontal or vertical alignment):

1. To activate the function from the shortcut menu of the main dialog box:

• Activate the alignment geometry (Input H or Input V).

• Place the cursor on the element (any element).

• Activate the shortcut menu, and select the menu option Append Combination.
