Geometry and Construction Sketcher Tool
In Creo Elements/Pro 5.0 (formerly Pro/ENGINEER Wildfire 5.0), there are separate sketching tools for creating points and centerlines. Namely, construction points, construction centerlines, construction coordinate systems and geometry points, geometry centerlines and geometry coordinate systems.
While some are familiar with the pre-5.0 functionality of being able to add axis points (e.g., in 4.0 for internal sketches only, use >Sketch >Axis Point), users can now make use of geometry sketch tools that allow entities to convey feature-level information outside of Sketcher. On the other hand, construction points, centerlines and coordinate systems are sketching aids and cannot be referenced outside Sketcher.
For example, in the case of a sketched curve, a geometry point will generate a datum point whereas in the case of a geometry centerline, this will create a datum axis. For an internal sketch of an extrude feature, a geometry point generates an axis through the point and normal to the sketching plane (identical to pre-5.0’s Axis Points). In the case of a sketched pattern, a pattern instance is created by a geometry point.
Some of the benefits of using these tools include the capability of adding information to the sketched curve features, simplifying dimensioning schemes and also minimizing the number of items in the model tree.
Design Animation and Assembly Exploded States
An exploded view of an assembly shows each component of the model separated from the other components. You can define and save multiple exploded views and then, toggle between these views.
What’s new in the latest release of Creo Elements/Pro (Pro/ENGINEER Wildfire 5.0) is that you can now animate exploded or unexploded sequences. Several config,pro options and model display dialog can help customize this process.
In addition, you can add exploded states to the animation timeline using Design Animation module. In combination with other options in Design Animation (such as transparencies, orientations, etc) you can generate useful animations for use in the manufacturing process. Also -in Design Animation- there is the capability to record these sequences for later use or presentation purposes in AVI or MPEG format.
Use of Intent Features in Creo Elements/Pro Mechanica
Intent objects are powerful Creo Elements/Pro features that are automatically created based on the model geometry. Intent objects are families of associated points, curves, edges or surfaces that logically define boundaries of geometry created or modified for the feature. Intent objects are regenerated for even small changes, such as modifications in the sketch.
In the latest release of Creo Elements/Pro (Pro/ENGINEER Wildfire 5.0) you can manually create intent objects in Mechanica using the Datum Reference tool. Mechanica allows you to select intent objects as references when creating simulation modeling objects in which surfaces, edges, curves, or points are available for selection. You can select multiple intent objects for a single simulation modeling object.
For example, several surfaces of multiple features are subjected to a pressure load. You can create a datum reference feature of all surfaces independent of the parent features. Two main advantages: if the parent feature changes form or shape then, the load will not require extra selection or deletion of references and, the selection of references is done with one single mouse click.
