By clicking on the links above you'll get a in-depth description of the different menus.

Object

The pull-down menu looks like this:

Select task...

Here it is possible to select the appropriate alignment task in Novapoint Base.

MOUS_ICO The function is also available from Alignment Design > Toolbar >  Select Task

Center Line from Road Model

This function uses the center line set in the active road model as the alignment.

MOUS_ICO The function is also available from Alignment Design > Toolbar >  Center Line from Road Model

Notes:

Pick Angular Points

This function creates a new alignment based on straight lines and simultaniously adds curves as set by the user or Design Standard.

Note: The Append Angular Points function does not force the alignment to start from scratch.

From Drawing

Use this function when wanting to select an alignment from the drawing. It is possible to choose single or multiple alignments, lines and polylines.

The first picked element sets the alignment direction. If more than one CAD element is selected the direction of the alignment will be consequential in the direction the alignment is selected. The direction of the alignment can be changed at any time with the Turn function.

MOUS_ICO The function is also available from Action buttons > Pick Object

From File...

This function opens an alignment based on file data. The file data can be on different file formats.

Alignment Data Formats

Horizontal Alignment data in the following formats can be used in Alignment Design:

Vertical Alignment data in the following formats can be used in Alignment Design:

When the horizontal alignment is loaded the function asks for the file with the vertical alignment. Select the appropriate file for the vertical alignment or press Cancel.

TenTable (*.TIT)

This is the most used filetype for Novapoint alignments. When choosing an alignment from a TIT-file, Novapoint performs a check for the SEG file with the same name as for the TIT file. The SEG-file contains the details of fixation, and Novapoint will use this information if it is present.

Name...

Use this function to save the alignment to a task in the Quadri-model. If a task already containing an alignment is selected, the previous alignment will be overwritten.

Notes:

Properties...

Use this function to add information you want to follow the alignment. Details defined in this dialog box will be saved in the files *.RES and *.NDB.

Start Chainage...

Use this function to define the first chainage for the active alignment.

Alternatively, the user can define the value for the start chainage based on a desired point on the alignment or globally. Novapoint will recalculate the start chainage when pressing Calculate Start Chainage.

Follow the below procedure to calculate the first chainage from other designed alignments, object in the drawing or a desired point on the alignment:

Step 1: Mark the check box Use Chainage at Point.

Step 2: Pick a point in the drawing using the button Pick Point < or manually insert the North and East coordinates. The point can be any of the following:

Step 3: Based on the current first chainage (at the field Start Chainage), the chainage at the point selected will be calculated and displayed at the field Chainage.

Step 4: Define the desired chainage at the field Chainage and click the button Calculate Start Chainage to find the new first chainage for the horizontal alignment. Observe the field Start Chainage.

Step 5: Click OK to apply and exit.

Note: When using this function on an alignment already in use as reference alignment, the road model will NOT BE UPDATED based on the changes. Therefore, the Road Model must be adjusted separately.

Automatic Quadri Save

The function gives the user the possibility to switch off the automatic saving of the alignment to the Quadri-model. The use of this function will give quicker response when doing changes in larger alignments because the communication between the Quadri-model and Alignment Design is cut off.

The user should use this function carefully, and it is recommended to use the Save only more actively or save by drawing out to CAD to preserve data from being lost unnecessary.

Export to File...

Use this function to export the designed alignment to files. The dialog box Save As will pop up:

Alignment data (horizontal geometry and/or vertical geometry) can be exported to the following formats:

Saving single files from tables:

Import NADB File

Use this function to import the horizontal alignment data from a NADB input data file. When importing from a NADB file, extension *.NDB, the properties and user defined fixed points will be included. Fixations will follow the *.SEG file if this is available.

Connect

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

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

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
