Alignment Design

How long alignment can I make before I have to split the alignment in parts?

Answer: Alignment design tool and the road model calculation supports upto 2500 elements. Wheater or not you need to split your alignment vary from project to project and the level of detail on the terrain making alignments slow in the vertical window. Note that the alignment design tool can be experienced as slow depending on what tasks are used as calculation basis or illustration objects. Longer alignments will lead to slower road model calculations because of the increased amount of data.

Dialog crashes

Answer: There are many possible reasons for the alignment design dialog to crash during start-up, picking a line, in use or when drawing out. Often it is a local factor/issue on the computer that has occured that are causing the issue. It might be settings on the computer, error in Novapoint, error in CAD-software, issues in the drawing or sometimes the lack of memory/RAM on the computer.

Everytime a crash occurs you should as minimum restart CAD if you are not forced to do it. Restart of Novapoint could also be necessary, but not always a must.

Below you will see som propositions to solve the issue you might experience. Some processes will reset settings to default so you might need to contact your IT department to get all your company setup back in order for the softwares Novapoint or CAD.

The error might be related to…

… using of the specific alignment in the drawing:

  • Do you experience the issue in other projects?
  • Make the same operation on a colleagues computer and se if the issue still occurs there in the same project and on the same alignment(s)
  • Delete the alignment from the drawing and draw it out again from Alignment Design. Try then to pick the alignment from the drawing. There might have been issues with the drawout.
  • Save the alignment as TIT/NYL or XML from the dialog and read it back into the project from file
  • Try to run Reset User Settings
  • Try to run Reset Settings to Default from AutoCAD (basically a “Reset User Settings” for CAD)

… issues with the drawing map or other XREF:

  • Try to restart the Alignment Design/pick alignment from a new empty drawing
  • Clean up potential errors or heavy drawings with different CAD-commands (CONVERT, PURGE, AUDIT etc)
  • It might be related to using UNC-filepath to the drawing or project
    • (UNC-filepath is of the type \\server-name\Project\Contract… and you must use “mapped network drives” of type M:\Project… or similar)

… missing files in the CAD-software:

  1. Close down Novapoint and CAD
  2. Start CAD alone (not through Novapoint)
  3. Close down CAD
  4. Start Novapoint and then CAD from Novapoint

… CAD-profile for Novapoint:

  1. Close down Novapoint and CAD
  2. Run CAD-software reset function: 'Reset settings to Default'
  3. Start CAD from Novapoint again
  4. Go to Options > Profiles
  5. Set “Unnamed profile” as 'current'
  6. Delete the Novapoint profile for your Novapoint version
  7. Close down CAD
  8. Start CAD from Novapoint again
  9. CAD-profile for Novapoint is now a new one
  10. Test Alignment Design

In some cases it will necessary to restore your setup according to some company profile to create these files as some customers have spesial setup for this. Contact your IT.

… graphics card:

  • Turn off the LineWeight in AutoCAD (command LWDISPLAY in CAD)
  • Turn off Graphic Performance in CAD (command GRAPHICSCONFIG in CAD)
  • Turn off all “SNAP”-functions (press F3, F4, F6, F10, F11 in CAD)

… software:

  • Reinstall Novapoint and/or CAD-software (normally not necessary but is a last resort)

If non of the solutions above work you might need to format your computer and install all again (!!!). !! As a last resort you should consider if it is time to get a new machine or swap/upgrade components.!!

Contact support to hopefully help you avoid these last proposed steps.

Error 400025: Coordinate referance system is not defined

Answer: Try to restart Novapoint or your computer.

Grip points are very big

Answer: Sometimes the grip points and numbers in the Alignment Design can be big and making it hard to see what you are working on. This is especially experienced when zooming in and making tight connections.

It can be solved by doing one of the following:

  • Change the drawing scale
    a) Make sure the correct drawing is selected (horizontal or vertical)
    b) In AutoCAD, go to the Novapoint ribbon
    c) Go to Scale and reduce the scaling. Press OK.
    d) Refresh the drawing by writing RE, REGEN or REGENALL
  • Turn off LineWeight
    In AutoCAD it is possible to turn off LineWeight by writing LWDISPLAY in the commandline. Set the value to OFF. It is also possible to turn this off via a button in AutoCAD.

I have a problem moving my alignment without it being "NOT OK"

Answer: If you have a complex alignment or an alignment with little flexibility you can help yourself by instead making a new alignment in the area where you want to move your projects alignment. If you manage to make this new alignment OK, then it should be simpler to move your project alignment to this location.

Start and end the new alignment perfectly aligned with the project alignment. Also start and end with the same fixation as the project alignment.

How can multiple elements be moved in parallell?

Answer: Mark the alignment so it is highlighted. Select the grip points you want to move while holding down the SHIFT button on your keyboard. Now move one of the highlighted grip points and they should all be moved together.

My alignment is never "OK"

Answer: There are multiple reasons why an alignment calculation is “NOT OK”.

  1. Fixation, is this set up correctly? Remember that there are many combinations for the fixation between the elements and this setup has to be correct.
  2. Poorly placed grip points for the elements. If the placement of the grip points does not allow for an OK calculation it will not work. When there is not enough room for placing the curves, clothides or straights it can be hard to find the correct placement for the grip points. Go back some steps by looking in the History-tab or Undo the latest changes. Maybe making the radiuses very small could help to make room for the straight lines.

Undo-button not working

Answer: Did you press the “correct” undo-button? The Undo-button in Alignment Design applies only for changes in the Alignment Design dialog, while the Undo-button in AutoCAD applies only to changes in AutoCAD except those done by the Alignment Design.

Alignment Design is slow

Answer: Sometimes the Alignment Design is noticably slow. This can be experienced with very long alignments, when there is a very detailed calculation basis/illustration objects or there are many stored alternatives in the Alignment Design history.

It is also possbible to turn off Automatic Quadri Save found in the pull-down Object menu and pressing the Automatic Quadri Save. When turning this off you should also save the alignment regularly to not loose data if something suddenly doesn't wrong. More about this here.
