Legacy Preferences

To access this screen, go to Options > Project Preferences > Legacy.
Line Types Displayed Across Stories: Select a line type with which to display the outlines of Slabs and Meshes that appear on stories other than the Home Story, as well as Objects and Stairs.
Note: This setting has no effect on Walls, Roofs or Shells, their Openings, or any elements in a Trace Reference.
Above Home Story: Use this pop-up palette to select a line type for Slab/Mesh/Object elements displayed above their Home Story.
Below Home Story: Use this pop-up palette to select a line type for Slab/Mesh/Object elements displayed below their Home story.
Note: These line types are only effective on Library Parts if the Use Symbol Linetypes checkbox in their Settings dialog boxes is switched off.
True 3D Projection: This display mode is available as of ARCHICAD 15. (All Multi-plane Roofs and newly placed Skylights will be shown this way.)
Symbolic: This display mode corresponds to the way Roofs and Skylights were displayed in ARCHICAD 14 and earlier.
Columns vs. Beams global priority (Legacy intersection mode only!): This slider defines the relationship between all Columns and Beams in the project. When Beams cross Columns, the element of lower priority will be cut in 3D, i.e., the intersection part will be removed. The element of higher priority will remain intact. This applies to volume calculations as well.
Note: Column priority numbers are always even and can only be defined as a general setting, in this dialog box. Beam Priority is set for each beam separately in Beam Tool Settings (Model panel – Legacy intersection mode only!).
To achieve this “old” logic, use the Legacy option at Options > Project Preferences > Legacy. When you migrate to ARCHICAD, this checkbox is On by default.
