Defining Cutting or Capping Surface References
Use the Define By field on the Results Surface Definition dialog box to indicate the references for cutting or capping surfaces. You can select from:
• WCS—Create the cutting or capping surface relative to the WCS.
• Three Points—Create the cutting or capping surface relative to an XY plane established when you select three points. The Three Points option provides you with a high degree of flexibility in how you define the cutting or capping angle relative to your model's geometry.
When you select this option, Creo Simulate adds a selection area to the dialog box. Use the selector arrow in this area to select the points. Creo Simulate treats the points as follows:
◦ First Point—Establishes the point of origin for the coordinate system
◦ Second Point—Establishes the direction of the X axis
◦ Third Point—Establishes the direction of the Y axis
• UCS—Create the cutting or capping surface relative to a coordinate system you defined for the model. The UCS you select must be Cartesian.
When you select this option, Creo Simulate adds a selection area to the dialog box. Use the selector arrow in this area to select the UCS.
• Screen—Create the cutting or capping surface relative to the angle at which you are currently viewing the model in the result window.
• Isosurface—Create the cutting or capping surface based on the nearest isosurface. This option is only available for fringe plots.
The Isosurface option behaves differently depending on whether you are working with cutting surfaces or capping surfaces:
◦ Cutting Surface—Creo Simulate displays the single isosurface whose range is nearest the value you specify in the Depth field.
◦ Capping Surface—
Creo Simulate displays the single isosurface whose range is nearest the value you specify in the
Depth field. It also fringes the model above or below the isosurface range, depending on the
location you select.
