Glazing Bars


  • Create the impression that a window is sub-divided in to a number of separate panes.


Generates a grid of rectangular glazing bars over a window polygons. The bars sit on the surface of the window and use a simple box profile, so are not suitable for close-up shots.

You can build glazing bars to multiple window polygons, of the same size, at once.


  1. Select one mesh item.
  2. Select one or more quad polygons. These should be of the same size if Group Polygons is disabled.
  3. Click on the Glazing Bars button to open the UI.
  4. Set options and Click “Apply”

User Interface



Reset Values
Reset values to their default. Note: Click this reset button before using this tool for the first time.
The depth of the glazing bar determines how far it protrudes from from the surface of the window.
The width or thickness of the bars when looked at from the front. Slimmer bars are more visually appealing, so try using values between 13mm (0.5 inch) and 25mm (1 inch).
Extend the bars beyond the border of the selected polygon/s by this distance. Use this option to ensure the ends of the bars overlap the window frame.
Horizontal Bars
Sets the number of horizontal bars.
Vertical Bars
Set the number of vertical bars.
Group Polygons
Selected polygons are treated as one entity and a single grid is created that covers the area of the selection. Note, all polygons must share the same normal.
Create the glazing bar geometry.


  • You can use this tool to quickly create a simple garden trellis.
  • Only supports create the bars over rectangular polygons.
  • Selected polygons must be quads i.e. polygons must contain 4 vertices.
  • Does not support X-up axis coordinate space; Switch to Y-up or Z-up axis to before using this script.
