Contours on Open Edges

“Open Edges” are Opening contours that do not intersect any other element, and do not coincide with another element’s edge.

Openings with Open (1) and Bound (2) edges

Display these Open Edges as Uncut, Overhead or Hide:

Open Edges as Uncut - Show as Overhead - Hide

https://helpcenter.graphisoft.com/wp-content/uploads/archicad-25/040_elementsvb/OpenEdgesContoursSlab.png 

Open Edges as Uncut - Show as Overhead - Hide

Note: This setting has no effect on Openings that coincide with e.g. a Slab edge. Such edges are “Bound edges,” and their display (Overhead or Uncut) depend on the Slab’s contour display.

Opening Contours

Define attributes for Uncut and Overhead contours. You can Use Contours of Cut Elements. Otherwise, the Opening’s own Uncut/Overhead attributes (defined in this dialog box) will be used.

Opening Cover Fills

See Assign a Cover Fill.

https://helpcenter.graphisoft.com/wp-content/uploads/archicad-25/040_elementsvb/CoverFillOpenings.png 

For “separated” display of divided openings, the cover fill is not shown in the air space.

The Opening’s symbol is placed on top of the opening (including its cover fill, if any.)

Opening Reference Axis
