Events

Events in Creo Elements/Direct Modeling are a method how a program gets notified about different actions going on in Creo Elements/Direct Modeling. The can be seen as a alarm clock that rings on certain circumstances and the allows the programmer to trigger the appropriate action.

The Creo Elements/Direct Modeling Integration Kit allows the programmer to specify a Lisp function that is then automatically executed when the corresponding event is triggered.

An example could be, that a program needs to update its data structures each time the Creo Elements/Direct Modeling parts tree is changed. In this case the you would specify a Lisp function to update the data each time the event is triggered that indicates a change in Creo Elements/Direct Modeling's parts tree.

Attributes

The Creo Elements/Direct Modeling Integration Kit provides a powerful attributes concept.

Attributes are a method to manage additional information attached to all kinds of Creo Elements/Direct Modeling items

Attributes can consist of whatever Lisp data types, e.g. text, numbers, programs. They can be attached, detached, set or inquired using the Creo Elements/Direct Modeling Integration kit.

Attributes may have different types. Depending on the attribute type, attributes are either temporary (within the current Creo Elements/Direct Modeling session only) or can be stored in different files such as in Creo Elements/Direct Modeling files, in Creo Elements/Direct Modeling layout files (MI files) or in standard data exchange format files like e.g. STEP files (not yet available).

Feedback Elements

Feedback elements are designed to show graphical feedback in a single or all viewports independend of any Creo Elements/Direct Modeling object or element. They provide a fast method to show simplified feedback which can be used as a preview without any change to the object tree. Different functions are provided to create different shapes like pyramid, cylinder, lines or text label.
