PREVIEWING CHANGES ON A GEOMETRIC DESIGN

摘要

Describe is a method for visually presenting, or previewing, changes to 3-dimensional geometry. In Onshape, a user may apply a sequence of configurable geometric operations in order to design a 3-dimensional model. When a user edits a specific operation, the method provides a way for the user to see the effects changes will have on a model. The method provides high-fidelity visualizations of the user's design as it would be before the operation is applied, after the operation is applied, and the operation's effects in conjunction with the effects of all operations in the sequence. The method also provides an interface for transitioning between these visualized states, allowing the user to effectively and efficiently understand the effect of the changes.

1. A method for previewing geometrical operation changes within a three dimensional computer aided design (3D CAD) software program, comprising:
operating a computer device to display a user interface of the 3D CAD program; displaying a preview interface after selection of a geometric operation to add or edit for a model within the user interface of the 3D CAD program; providing a preview control within the preview interface, wherein the preview control allows selection between a before operation display, an after operation display, a blend of before and after display, and a complete preview; and rendering, within the user interface, the model based on the preview control selection while changes are made to parameters of the geometric operation.
