Work with Section Planes & Section Boxes

Overview

The BIM Viewer supports multiple section planes and a section box, which allow you to focus on specific areas by cutting through the 3D model. Sections allow to position the camera outside and see all relevant information within the model.

Section Box

Similar to section planes, the section box allows you to slice the model. The section box will create six section planes around the bounding box of an element. Anything inside the box remains visible, while everything outside is hidden.

Only one section box can be created at a time.

Create Section Box

To create the section box:

  1. Select the element(s) you want to isolate in the section box
  2. Click/tap the box icon

  3. The element(s) selected will be isolated in a box

  2. Drag the face to expand or reduce the section box
