The Opening Tool is one of the new features of ARCHICAD 23, a must-have BIM design tool for the modeling, information management and documentation of openings. Use the new Opening Tool to create holes and recesses/niches that penetrate any number of model elements. They are relevant for architecture, structural engineering and MEP engineering disciplines. They are exchanged many times between disciplines throughout the design process.

Creating a New Opening

ARCHICAD 23 gives you the opportunity of placing an opening into a wall, a slab, a beam or a mesh following these steps:

  • In the Floor Plan or 3D Window, activate the Opening Tool
  • As you move the cursor over the target, you will see a preview of the opening at its current location.
  • Click to place the opening at the desired place.

While an opening can cut and be connected to several elements, one element is defined as the associated element. This means that the opening is linked to the associated element. The associated element is the "owner" or "parent" of the opening.


Use the opening's grip to manage its connections to construction elements:

  • Add new elements to be cut - use the plus sign
  • Remove cut/connected elements - use the X sign
  • Change the designated associated element - use the pin icon


The position of the opening is defined relative to its associated element and moves along with it. If you move any other connected cut element, the opening’s original position does not change.
