Design Objects

Use this function to define the design objects (curbstone, guardrail, etc.) in the road model. Such defined objects can be:

A design object is a drawing file defined by the designer.

The designer creates the design object; a drawing file representing the design object (eg. guardrail). The drawing file is saved to the disk with the insertion point as (0,0,0). The insertion point is used to define the object to the road model.

Run the function from the following locations of the floating window Road Model:

MOUS_ICO Toolbar: Not available from Toolbar

MOUS_ICO Menu: Data > Design Objects

Define the object in the dialog Design Objects.


Define the first and last chainage of the design object.

Note: The columns are sorted upon re-opening the DWG File dialog.

Select the drawing file that has the design object.

Insertion Point



Select the road surface or the alignment, which forms the baseline for insertion of the design object.


The position of the design objects can be shifted from the insertion point using the horizontal and vertical offset fields.


Design objects can be rotated to follow the road surface using the option As Road Surface. The choice None applies no rotation. The baseline for the rotation is the baseline found in the DWG file.

Cross-section Viewer

Note: The road model needs to be calculated in order to view the changes in the cross-section window.

Cross-sections from Road Model

Design objects are available to select when presenting the cross-sections from the road model.
