StructuralSurfaceMemberOpening

Opening in surface member

Instances of StructuralSurfaceMemberOpening describe openings in face members (StructuralSurfaceMember). The geometry of the opening object is defined in the same way as geometry of 2D members - may be planar or curved with an arbitrary number of edges.

Data type

Example / enum definition

Required

Description

Name

String

O1

yes

Human readable unique name of the object

2D Member

String

S13

yes

The name of the StructuralSurfaceMember to which is the opening situated.

Nodes

String

N81; N263; N659; N660

yes

All nodes that belong to the surface member and define its geometric shape. The names of the nodes are separated by ; (semicolon) and space.

Edges

String

Line; Line; Line; Line

yes

Defines the shape of the curve between two next nodes. Supported shapes are: Line; Bezier; Circular Arc; Parabolic arc; Spline; Circle and Point; Circle by 3 points. The names are separated by ; (semicolon) and space.

Area [m2]

Double

1.259

no

The value of the surface area of the StructuralSurfaceMemberOpening

Parent ID

String

67b35d84-3d04-47aa-aa4a-dc1263982320

no

Is filled for objects created be dividing curved geometry to series of straight line objects. Parent ID will ensure that curved edge is imported as straight parts to nonsupporting application, and back to original supporting application as curved geometry. To ensure successful round trip of segmented objects and their related objects, Parent ID needs to be present in both directions.

no

Unique attribute designation

Notes

The edges of one opening can’t touch nor cross each other. When necessary, create two or more openings instead.
