Opening Element

Supported attributes

MEP Systems
Attribute Description
id This attribute is a hyphen-separated string, consisting of a prefix, op and a sequential number. For example, op-1.
Name Surface and Opening elements get an Name element assigned according to the below described schema:

(Orientation)-(Space#)[-(Other space#)]-(Exposure)-(Type)-(sequence number) [Opening Type+#]

Sample:

N-101-102-E-W-D-84

N = Orientation [N/NE/E/SE/S/SW/W/NW/N/T/B/X]

(every surface within the sector of 22.5 degrees from the north vector gets the letter N etc) (horizontal surfaces facing upwards get the letter T for top, downwards B for bottom) (shading surfaces get the letter X for differentiation)

101 = Space number

102 = Other space number

E = Exposure - exterior/interior/underground [E/I/U]

W = Type [W/C/R/F] (Wall, Roof, Ceiling, Floor, Shade) (every surface type has it's letter W-Wall R-Roof C-Ceiling F-Floor S-Shade)

O = Opening Type [W/D/O] (Window, Door, Opening) (every opening type has it's letter W-Window D-Door O-Opening)

77 = sequence number

Sample surface names:

N-101-E-W-84 North facing Exterior Wall #84 in space 101

N-101-E-W-84-D-1 Door #1 in North facing Exterior Wall #84 in space 101

E-101-102-I-W-92 Vertical Interior Wall #92 between space 101 and 102

T-101-E-R-141 Top facing Exterior Roof #141 in space 101

B-101-201-I-F-88 Bottom facing Interior Floor #88 between space 101 and 201

X-73 Shade #73

openingType The value for this attribute is based on the family category for the opening and the element in which it is contained:

For a Window, the type is OperableWindow.

For a Door, the type is NonSlidingDoor.

For an opening contained in a Roof, the type is OperableSkylight.

For a Curtain Wall Panel, the type will default to type FixedWindow. A Curtain Wall panel having a material and the material is not transparent (less than 3% transparency), the type is solid panel. Otherwise it is treated as a FixedWindow. For a Curtain Wall Panel having no material, the type is FixedWindow.

For an opening of the category Openings, the type is Air.

constructionIdRef This specifies a unique id for the Construction element that is associated with this opening.
