When the Find Nearest CAD Element button is clicked, PC-DMIS locates the nearest CAD element in the Graphic Display window based on the XYZ location and any selected axis (or axes). PC-DMIS allows you to either type or surface-select the pertinent information.
Understanding Axes Check Box Selecting
For Vector Points or Surface Points - If you select an X, Y, or Z axis check box, PC-DMIS interprets the selection as the axis that will be modified when you click the Find Nearest CAD Element icon.
For Edge Points or Angle Points - If you select an X, Y, or Z axis check box, PC-DMIS interprets the selection of the axis as a selection of the one axis that will NOT be modified when you click the Find Nearest CAD Element icon. For example, if you select the X check box, PC-DMIS actually select the Y and Z check boxes signifying that the Y axis and Z axis values will be modified by the Find process.
Understanding the Find Operation without Selecting Axes Check Boxes
For Edge Points and Angle Points - If you click the Find Nearest CAD Element icon without an axis selection, PC-DMIS finds the closest CAD edge or angle point.
For Vector Points and Surface Points - If you click the Find Nearest CAD Element icon without an axis selection, PC-DMIS finds the closest CAD along the Normal vector specified in the dialog box. PC-DMIS then populates the dialog box with the found vector.
