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:
After editing the center line in current road model, remember to rebuild the Road Model.
Changes in the horizontal alignment will influence the road model in several ways.
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.
The sequence of the elements will be line-arc-line.
By default, the standards of arc (radius/length) will be based on the settings defined at Design Standard.
Radius of the curve can be changed from the command prompt while picking a angular point.
Cancel the previous angular point using the Undo option in the command prompt.
Finish picking angular points using the key Return or right-click.
The function is to be used to start the alignment design. To append (continue adding elements to the alignment) use the function Append Angular Points (under Modify below).
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:
*.TIT - Standard format for the NADB result data (Horizontal Geometry)
*.LIN - POINT/SBG format for the Horizontal Geometry
*.LI - Intergraph format
*.DAT - Intergraph format
*.TXT - XROAD format
*.ISL - ISPOL format
*.XML - LandXML format
Vertical Alignment data in the following formats can be used in Alignment Design:
*.NYL - Standard format for the Vertical Geometry result data
*.PRF - POINT/SBG format for the Vertical Geometry
*.TXT - XROAD format
*.ISL - ISPOL format
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:
When using the action button OK - Draw, or one of its similar buttons from the pull-down, the alignment will be saved to the alignment task.
The changes in the alignment will not be saved if the program or dialog box terminates.
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.
By default the first chainage is 0.0000m
User can define any value (positive or negative) as first chainage.
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:
Any point on other designed alignments.
Any object in the drawing.
Any point on the current alignment itself.
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.
This value can be edited and whole chainage can be recalculated (using the button Calculate Start Chainage) with this value as reference.
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:
Select from the drop-down list (at the field Save as type) the combination of files to be saved.
Alignment data (horizontal geometry and/or vertical geometry) can be exported to the following formats:
*.NDB - Standard format for NADB input data (Horizontal Geometry)
*.RES - Standard format for the NADB result report (Horizontal Geometry)
*.TIT - Standard format for the NADB result data (Horizontal Geometry)
*.SEG - Standard format for the NADB horizontal fixation data
*.NYL - Standard format for the Vertical Geometry result data
*.LIN - POINT/SBG format for the Horizontal Geometry
*.PRF - POINT/SBG format for the Vertical Geometry
*.LI - Intergraph format
*.DAT - Intergraph format
*.TXT - XROAD format
Saving single files from tables:
Saving a single NDB file can be handled from the NADB In H tab of the dialog Alignment Design.
Saving a single RES file can be handled from the NADB Res H tab of the dialog Alignment Design.
Saving a single TIT file can be handled from the NADB Ten H tab of the dialog Alignment Design.
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.
