Abstract

Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a model including a plurality of geometries, at least one of the geometries being underdefined. The method includes displaying the model and detecting motion using a motion-sensing device. The method includes perturbing at least one of the underdefined geometries in response to the detected motion and according to an unconstrained freedom of that geometry. The method includes displaying the model while perturbing the at least one of the underdefined geometries. The method can be performed by a handheld device.

Claims

1. A method for displaying underdefined freedoms in a partly-constrained geometry model, the method performed by a data processing system and comprising:

receiving a model including a plurality of geometries, at least one of the geometries being underdefined;

displaying the model;

detecting motion using a motion-sensing device;

perturbing at least one of the underdefined geometries in response to the detected motion and according to an unconstrained freedom of that geometry; and

displaying the model while perturbing the at least one of the underdefined geometries.

2. The method of claim 1, wherein the motion-sensing device includes an accelerometer.

a processor;

a motion-sensing device; and

an accessible memory, the data processing system particularly configured to

receive a model including a plurality of geometries, at least one of the geometries being underdefined;
