Appeal No. 95-4605
Application 08/076,285
This is a decision on appeal under 35 U.S.C. § 134 from the
final rejection of claims 1-16, all of the claims pending in the
application. We affirm-in-part.
The disclosed invention is directed to a computer aided
design (CAD) system which includes a replication command which is
stored in unexecuted form and the number of replications to be
made of a selected structural object is stored as a variable. As
described in the Brief (page 2):
When the generic program containing these variable
replication commands is executed to render an output image,
the variables need to be substituted with specific values.
In general, for execution, a CAD user merely inputs specific
values for modifying the shape of a selected object as well
as the replication number. In response to these user
inputs, the CAD system executes the program and completes
the replication of the selected object "on the fly."
Claim 1 is reproduced below.
1. A method for generating a generic program of a
graphical model of a 2- or 3-dimensional object with at
least partially variable dimensions, in a computer aided
design system, said design system having design commands,
said method comprising the steps of:
selecting a sub-group of geometric elements
corresponding to a structural element of said object,
wherein said geometric elements are defined by a set of said
design commands;
generating a replication command having replication
parameters defined as variables, said replication parameters
being generated in relation to said sub-group of geometric
elements;
incorporating said replication command and said
replication parameters into a design program thereby
