Curve to Surface
KeyCreator \ Verify \ Deviation \ Curve-to-Surface

Location: Tools>Verify>Deviations>Curve to Surface

This function will measure for maximum deviation from any curve entity to a surface to verify congruency or constant offset value.

Using the Function:

1      Select Curve to Surface from the Verify>Deviations submenu.  The Curve to Surface Deviations dialog box appears.

  • Number of test points - along the specified boundary.

  • Position tolerance - The minimum positional deviation tolerance for which points will be displayed

  • Normal angle tolerance - The minimum angular deviation tolerance for which vectors will be displayed.

2      Either accept the preset default values or select the parameter you wish to change.  Adjust the values as needed.

3      When all values are satisfactory, click OK to initiate the evaluation.

4      Select a face.

5      Select the curve.

6      The Data Verify dialog appears, displaying data specific to the entities you selected.  Contained in this dialog is the calculator feature.  A specified number of points will be distributed along the specified curve.

  • Each point will be evaluated for its minimum distance to the specified surface.  Also, a vector that is tangent to the curve at each point will be checked for tangency to the adjacent surface.

  • If any points exceed a specified 'deviation tolerance' threshold or if any tangents exceed a speci­fied 'angular tolerance' threshold, this data will be reported back to the user as permanent entities displayed on the screen.

7      Review the Data Verify information, and select NEXT to select additional geometry to verify.  When you have finished verifying, click CLOSE.
