v3.5 Errata and Addendum for
"Dimensioning Features"
ADDED JULY 31, 2002
In the English printed and possibly the foreign language versions as
well, the topic "Dimensioning Coaxiality", on the second paragraph,
contains this erroneous first sentence: "PC-DMIS will display a message,
asking you to you will receive an error message. " It should be deleted.
- - - - -
ADDED SEPTEMBER 19, 2002
In the "Display As Radius" topic for True Position dimensions,
the following note regarding this the "Display As Radius"
check box was added:
"Important: If you use this check box, be aware that it is not compliant with ISO standards."

ADDED DECEMBER 04, 2002
The first paragraph in the "Dimensioning Runout" topic should
be rewritten as follows:
"The Runout menu option determines the runout of the first feature with respect to the second feature (i.e., the second feature becomes the datum feature). If only one feature is selected, the origin and the work plane become the datum feature. In this case, PC-DMIS uses the position from the origin and the direction from the workplane for the datum. The text in the Edit window for the datum feature will read 'THE ORIGIN'."
ADDED DECEMBER 05, 2002
The bulleted list immediately following the introductory paragraph in
the "Dimensioning Symmetry" topic should have this addition:
· If the third feature is a plane, the symmetry algorithm attempts to find a line on that plane that represents the datum. To find the correct line, it intersects (or crosses) the chosen plane with the work plane. For this reason, you should ensure that you are using the correct work plane.
ADDED APRIL 2, 2003
The initial paragraph in the "Relationship for Angle Between Dimensions"
was incorrect. It should be rewritten as follows:
The check boxes in the Relationship area of the dialog box allow you to specify whether the the Angle Between dimension can calculate the angle between two features, or between one feature and a particular axis: X axis, Y axis, and Z axis.
Also, documentation for the "To Feature check box" for distance dimensions has been updated to read as follows:
- - - - -When you select the To Feature check box, the Perpen To, or Parallel To options in the Orientation area become available for selection. These options tell PC-DMIS to compute the distance between the first selected feature and the second selected feature parallel to, or perpendicular to a certain feature.
- If only two features are selected from the list, PC-DMIS computes the distance between feature 1 and feature 2, parallel or perpendicular to feature 2.
- If three features are selected from the list, PC-DMIS computes the distance between feature 1 and feature 2, parallel or perpendicular to feature 3.
The feature used to establish the relationship should be a linear feature.
