Offset 3D-lines

Use this function to design 3D objects (kerb stones, hard shoulders, carriageway edge structures, etc.,) along an existing line (base line) and draw the plan of the same object.

MOUS_ICO Menu: Landscape > Terrain design > Offset 3D lines
MOUS_ICO Toolbar: > Terrain design > Offset 3D lines

The dialog box 'Create Parallel 3D-Line' will pop up.

  • The graphic area displays the road edge cross-section and the parameters to define the road edge.
  • Any changes made to the parameters of the section are reflected in the graphic area.

a, b, c, h, s and 1 are the parameters as explained in the graphical preview of the dialog box. Define these parameter values at respective fields.

Pick the baseline <

Use this button to select the baseline, along which plan of the 3D object is to be drawn. Command prompts for:

Select a baseline:

Select the desired baseline.

Select side of baseline for Kerb:

Pick a point to the left side or right side of the baseline. The 3D lines of the object will be drawn to the respective side.

Maximum length each line

The 3D lines of the 3D object consist of short straight-lines without arcs or transition curves. The length of each straight-line is to be specified at the field 'Maximum length each line'. Define a numeric and confirm with the key 'Return'.


Draws all the plan lines as 3D lines consisting of straight-lines only with the given parameters.

Select Template

Use this option for the following:

  • To draw the cross-section of the active 3D object.
  • To define new cross-sections and save them.

The dialog box Cross-Section Template will pop up with the button Select Template.

Widths and Cross Slopes

All the existing (user-defined) cross-sections will be listed in the pull down menu.


Use this button to create new cross-sections.

  • To define a new cross-section, define a name for the cross-section and click the button 'New'.
  • Use the fields a, b, c, h, s, and 1 to design the cross-section.
  • To save the cross-section, use the button 'Save'.


  • The cross-sections will be saved in the project file (*.NCP). For further details, refer the topic 'Project ID'.
  • Saved sections are listed in the pull down menu in the right pane of the dialog box.

Draw Cross-Section

Use this button to draw the cross-section. Command prompts for:

Select a point:

Pick an insertion point for the cross-section. The insertion point is the outer bottom most point.

Enter direction by pointing:

Pick a point, which indicates the direction from the kerbstone to the walkway.

Reset values

Resets all parameters to default values for the selected section.

Novapoint Customized Object menu (NCO)

To edit, run the function Object menu (NCO) from the menu Novapoint or toolbar Novapoint Base or command line NCO. Select the object, which is to be edited. Select the option 'Edit' from the pop up menu.

Depending on the object selected, respective dialog box will pop up, which facilitates to edit the selected object.
