Use For

  • Easy selection of walls or other polygon surfaces based on matching normals.
  • Ideal for creating a polygon selection prior to applying materials, projecting UVs and more.

Overview

Selects all polygons whose normal matches that of a previously selected polygon, and permits refinement of the selection based on a variety of filters; e.g. you can limit selection to polygons in the same plane as the target polygon.

Workflow

  • Select one or more mesh item layers.
  • Select a single polygon.
  • Click on the 'Select by Normal' button in the mARCH Classics UI to open the command's sticky pop-up window
  • Set your selection filters/criteria.
  • Click the 'Select by Normal' button in the pop-up window.
