Notes on Adjustment Rules

Rules are applied in the order they are listed, and they are all carried out. You can drag rules to change their order.

Generally, the Offset rules come at the top of the list: they are used not to create connections per se, but to line up the elements so that the rest of the rules (Stretch, Cutback) can work as needed.

Hover over any Adjustment Rule to see an info pop-up, showing its parameters and a preview.

Use the buttons at the bottom of the Adjustment Rules panel to Add or Remove rules.

Important: If you remove a Rule, the associated adjustment is no longer applied, and the Structural Analytical Model reverts to its original position!

One to the other: https://helpcenter.graphisoft.com/wp-content/uploads/archicad-25/090_structuralanalyticalmodeltools/OneToOther.png The Members in the left column are modified; the Members in the right column remain unchanged. Use this method to Stretch and/or Cutback, or Offset one group of elements to each other. The Offset and Snap adjusters always use this unidirectional method.

To each other: https://helpcenter.graphisoft.com/wp-content/uploads/archicad-25/090_structuralanalyticalmodeltools/ToEachOther.png Members in both categories are affected. Use this method to Stretch and/or Cutback two groups of elements to each other.
