Y Direction for Gaps

You specify the orientation of the XY plane of a gap by selecting one of the entities below. Creo Simulate defines a Z direction normal to this XY plane, and defines a Y direction that is perpendicular to the X and Z vectors.

The X vector for a gap is defined by the gap length, which is the shortest distance between the entities used to define the gap. For a zero-length gap, the X direction is normal to the surface.

You can select the Y direction to define the orientation of the XY plane of a gap by selecting one of the following options:

• Y-Direction defined by Point—Defines the XY plane with the gap X vector and the selected point.

• Y-Direction defined by Edge—Defines the XY plane with the gap X vector and the projection from the first point of the gap to the selected edge.

• Y-Direction defined by Curve—Defines the XY plane with the gap X vector and the projection from the first point of the gap to the selected datum curve.

• Y-Direction defined by Axis—Define the gap's XY plane with the gap's X vector and a parallel vector to the selected axis, passing through the gap's start point.

• Y-Direction defined by Surface—Defines the XY plane with the gap X vector and the projection of the first gap point to the selected surface.

• Y-Direction defined by Vector in WCS—Defines the XY plane with the gap X vector and a line projected from the first gap point in a direction parallel to the X, Y, or Z vector in the WCS. The default vector is 0, 1, 0, which defines the Y direction in the WCS.

• Not Defined—The gap definition does not include a Y direction. You cannot select this option if you output to the NASTRAN solver. Creo Simulate blocks output to NASTRAN if the Y direction for gaps in the model is not defined.
