ISO 10303-214:2010(E)
A Square_u_profile is an open profile that is bounded by three lines. One is the base line and has a defined length. The other two lines begin at the ends of the base line and extend infinitely. The corners of a Square_u_profile may be blended by a radius. The x-axis of the inherited Axis_placement is parallel to the base line. The y-axis is orient such that the side lines of the outline of the profile have positive y co-ordinates. The Axis_placement is located in the midpoint of the base line.
EXAMPLE Figure 68 depicts a Square_u_profile.
A Square_u_profile is a type of Open_profile.
The data associated with a Square_u_profile are the following:
The first_angle specifies the size of an angle between the base and that side of the profile that intersects the x-axis at a positive value.
See square_u_profile to feature_parameter for the application assertion.
The first_radius specifies a radius shape blend between the base and that side of the profile that intersects the x-axis at a positive value.
See square_u_profile to feature_parameter for the application assertion.
The first_radius need not be specified for a particular Square_u_profile.
The second_angle specifies the size of an angle between the base and that side of the profile that intersects the x-axis at a negative value.
See square_u_profile to feature_parameter for the application assertion.
The second_radius specifies a radius shape blend between the base and that side of the profile that intersects the x-axis at a negative value.
See square_u_profile to feature_parameter for the application assertion.
The second_radius need not be specified for a particular Square_u_profile.
The width specifies the size of the base line for a Square_u_profile.
See square_u_profile to feature_parameter for the application assertion.
