Create Parallel 3D - Lines
Use this function to design 3D objects (curbstones, hard shoulders, carriageway edge structures, etc.) along an existing line (baseline) and present the same in plan.
Procedure
Select the option Select Template.
Use an existing template or create a new cross-section.
Modify the active template if required.
For further details, see Select Template below.
Define the maximum length of each line in the 3D parallel lines being created (for break points).
Pick the baseline, along which the cross-section is being created.
Present the cross-section in the plan using the option Draw.
Run the function from the following locations:
MOUS_ICO Toolbar: Elevation Tools: Create Parallel 3D - Lines
MOUS_ICO Menu: Road > Elevation Tools > Create Parallel 3D - Lines
The dialog Create Parallel 3D-Line will pop up.
The graphic area illustrates the parameters to define the cross-section.
Tip: Shortcut to this function:
MOUS_ICO Toolbar: Novapoint Base: object_menu
Command prompts for:
Select an Entity:
Pick a 3D Polyline (Baseline).
Select the flyout menu option 3D - Lines.
Select side of baseline for Kerb:
Pick a point to the left or right side of the baseline to define the direction of the object.
Select Template
Use this option for the following:
To select an existing object template.
To modify an existing template.
To create a new object (cross-section).
To draw the cross-section of the active template.
The dialog Cross-section Template will pop up with this option.
All the existing templates will be listed in the pull-down menu at Width and Cross Slopes.
Select an existing template.
The active template will be displayed in the preview.
Hit the button OK.
Modify an existing template
Select the template that is to be modified.
Modify the cross-section using the parameter under Widths and Cross Slopes.
Any changes made to the parameters of the active cross-section are reflected in the graphic area.
Hit the button Save.
Create a new cross-section (object)
Select a suitable template.
Name the template at the edit field next to the button Save.
Modify the cross-section using the parameters under Width and Cross Slopes.
Hit the button New.
Note: The cross-sections will be saved in the project file (*.NCP).
Draw Cross-section
Use this option to draw the cross-section of the active template.
Command prompts for:
Select a point:
Pick an insertion point (baseline) for cross-section.
Enter direction by point:
Pick a point that indicates the direction from the cross-section with the baseline (left/right side).
Widths and Crossfall
a, b, c, h, s, and 1 are the parameters as illustrated in the preview of the dialog Create Parallel 3D - Lines.
Modify the parameters if required.
Reset Values
Resets all parameters (if changed) to original values of the template Kerb.
Line Control
Use this option to add more break points to the parallel 3D lines in the plan for the active object.
The length of each straight line is to be specified at the field Maximum length each line.
The smaller the length, the parallel 3D lines will follow the baseline relatively well.
Define a value and confirm with the key Return.
Pick Baseline <
Use this option to pick the baseline, along which the 3D parallel lines in the plan are to be drawn.
Command prompts for:
Select a baseline:
Pick the baseline.
Select side of baseline for Kerb:
Pick a point to the left or right side of the baseline to define the direction of the object.
Tip:
Select a 3D line as a baseline.
Do the following to generate 3D lines for the surfaces of the road model:
Build the wireframe model.
Turn off all the groups except the wireframe model groups in the database (Quadri Model).
Run the function draw_map_from_terrain_model.
Refer Create 3D - Line to create 3D polyline from a 2D polyline.
Draw
Use this option to present the 3D parallel line.
Object menu (NCO)
For the associated functions of the lines drawn using this function, run the function object_menu.
