Cross Section

Tools > Cross Section

Enable Activate button to define a cross-section plane.

TIP: The main section plane (as defined in the first tab of the above window) acts as a drawing area when snapping-to-cross-section-plane from the Actionbar is activated.

Plane Definition

We offer two ways to define a cross-section plane:

  • First, adjust the orientation of the plane by two angles.  is the angle between the plane and the ground plane.  is the rotation angle of the plane around the z-axis. Then select a point on the target plane. You can manually define the coordinates of this point, or you can click Set origin and then choose a location on the viewport.
  • You can also define the plane by three non-collinear points. Click Set from 3 points and then select three points on the viewport.  
TIP: Both Set origin and Set from 3 points, respect snapping tools that can be activated from the Actionbar.
TIP: Prematurely exit the selection mode with the Esc key.

Display mode

Change the appearance of the plane to one of the following:

  • Choose None to make the plane invisible. 
  • Choose Transparent to show the plane as a big blue transparent rectangle.

Additional Options

  • Enable Clip geometry to clip the scene against the cross-section plane. 
  • Toggle Invert cut to invert the direction of the cross-section plane so that the opposite side of the scene is visible. 
  • We show a preview of points in a distance of Proximity Threshold to the plane. Click Create Section to project these points onto the plane and generate a 2D point cloud from them. 

You can take up to three cross-sections at the same time. Use Auxiliary section tabs for this.
