Section from 3D Drawing

Use this function for:

Each 3D Face entity is represented with a line in the resulting cross-section or longitudinal section. The non-graphical CAD properties of the line will be inherited from the source entity. All lines in the result will be drawn to appropriate layers. It is possible to prefix the layer names. If the source entity is a 3D polyline or polyline with elevation, a point will be drawn to represent its location.

Note: Ensure that PDMODE of AutoCAD is set to a value greater than 2.

Figure: Cross-sections from a 3D drawing


Run the function from:

MOUS_ICO Toolbar: Not available from the Toolbar

MOUS_ICO Menu: Novapoint > Terrain Information > Section from 3D drawing

KEYB_ICO Command Line: Not available from the command line

The dialog Section from 3D drawing will pop up.

Using the radio buttons, choose 'Single Section' to present the longitudinal section or 'Sections along alignment' to present the cross-sections along the baseline.

Single Section


Sections along alignment

Note: The first point of the CAD entity will be the start point for calculations and presentation in case the baseline is a CAD entity.

Output Parameters

The active Terrain model and the baseline/section line information can be viewed in this dialog.

Cross-section Selection

This option is available if Sections along alignment is the choice at step 1. Define the first and last chainage between which, cross-sections are to be presented.

Drawing Settings

Tip: Negative spacing will present the cross-sections from top to bottom
