It is possible to save elements as Library Object which can be used as custom Treads. Any ARCHICAD element can be turned into a custom Tread Library Object. This article describes you how to create a custom Tread using the Morph Tool.

  • Navigate to the 'Structure' option (left side of the dialog) and uncheck 'Structure' on the right.
  • Select 'Finish' on the left.
  • Check 'Uniform Finish on Flight and Landing' on the right side of the panel.
  • Select 'Tread' for the 'Finish' (right side of the dialog)

  • A Dialog pops up, close it by clicking on OK.
  • The Tread needs to be saved into the Embedded Library (by default),  the 'Save Tread' dialog pops up, where proper name and location should be defined. Click on 'Save'.
  • A Ghost preview will appear in the 3D window. With this preview you first need to define the position of the Tread. You need to find the middle point.
