ISO 10303-214:2010(E)
A Ngon_profile is a profile that is composed of 3 or more connected straight and co-planar lines. One side of the Ngon_profile is parallel to the x-axis of the inherited Axis_placement of the profile. This side intersects the y-axis at a negative value as shown in Figure 49. The centre of the Ngon_profile coincides with the centre of the circle defining the extent of the ngon outlining the profile.
A Ngon_profile is a type of Closed_profile.
The data associated with a Ngon_profile are the following:
The circumscribed_or_across_flats specifies whether the diameter defining the Ngon_profile is the circumscribing diameter or tangent to the sides.
The following values shall be used:
The corner_radius specifies the size of an arc blend between any two sides of the Ngon_profile. The corner_radius shall be smaller than
See ngon_profile to feature_parameter for the application assertion.
The corner_radius need not be specified for a particular Ngon_profile.
The diameter specifies the diameter of the circle used to define the Ngon_profile.
See ngon_profile to feature_parameter for the application assertion.
The number_of_sides specifies how many sides are needed for the Ngon_profile.
