Appeal No. 95-1296
Application 08/073,257
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 10, 12-16, 21-26 and 29-
33, which constitute all the claims remaining in the application.
An amendment after final rejection was filed on April 26, 1994
and was entered by the examiner. This amendment resulted in the
withdrawal of a rejection of claim 15 under the second paragraph
of 35 U.S.C. § 112.
The claimed invention pertains to a method and apparatus
for storing and displaying data representative of a three
dimensional image of an object. More particularly, the invention
concerns the linking of data relating to a face of the object, a
datum plane and tolerances associated with the object so that the
relationship of this data is retained even when the view of the
object is changed.
Representative claim 10 is reproduced as follows:
10. A method for dimensioning and tolerancing an object
which includes a plurality of geometric elements on a display
screen of a computer, said computer having means for storing
data, said object shown in three dimensional space and having a
selected dimension which can vary by a selected tolerance, the
method comprising the steps of:
defining a first datum mathematically in three
dimensional space, thereby creating a mathematical description of
the first datum;
labeling said first datum;
