About Filters and Selection
Creo Parametric provides various filters to help you select items. These filters are located in the filter option list on the Status Bar. Each filter narrows the item types that you can select enabling you to easily locate the item.
Selection filters are of two types.
Compound Selection Filter — Enables selection of more than one type of object. For example, Geometry selection filter is a pre-defined compound selection filter which includes the selection filters for edge, surface, datums, curves, quilts, and annotation.
Individual Selection Filter — Enables selection of only one type of object.
Assembly mode: Vertices, Parts, and Features.
Part mode: Vertices and Features.
You can press Alt + mouse button to exclude the selected filter. For example, in an assembly, if you select Geometry as a selection filter, and press Alt + mouse button, you can select feature, parts, or vertices, without switching the filter.
When you select a geometric entity, in Part mode, the commands of the extended context that are displayed are relevant to the owner feature of the selected geometry plus the selected geometry. In an assembly mode, the commands of the extended context that are displayed are relevant to the part owner of the selected geometry plus the selected geometry. For example, in an Assembly mode, if you select an edge, the extended commands are displayed related to the part owner plus the selected edge. However, if you activate a part mode in the assembly, and if you select the same edge, the extended commands are displayed related to the feature owner plus the selected edge.
All filters are context-sensitive, so that only those filters that are valid for the geometrical context or that are required to meet feature tool requirements are available. The list of filters available in the Filter box are determined by mode and tab that is active. Additionally, Creo Parametric automatically selects the best filter according to the context. Remember that you can always explicitly change the filter by simply selecting another one from the Filter box.
My Filter
Creo Parametric allows you to define your own selection filter. The filter you define appears at the top of the selection filter list in the Filter box as My Filter. You can add more than one filter to My Filter. You can define a selection filter for each mode.
Geometry-Based Selection and Mini Toolbar
A new selection filter is provided so that you can prehighlight surfaces and edges by default. Click to select the geometry and to open a mini toolbar with direct access to frequently-used commands that you can perform, based on your selection.
When selecting geometry in the graphics area the corresponding feature or part is automatically highlighted in the Model Tree, expanding the Model Tree node if necessary. When you change the selection, any nodes that were automatically expanded are collapsed.
The mini toolbar is also available when you click items in the Model Tree and the option, Zoom to Selected, is added to the mini toolbar. This command Zooms the graphics area to place the selected feature in the center of the screen.
Selecting a geometry in a part provides direct access to commands in the mini toolbar. For a selected surface, this can include commands such as Plane, Axis, Sketch, and Hole, among others.
In addition, there are also commands related to context beyond your actual selection. This is referred to as extended context. Typically, extended context of selected geometry is the owning component when working in an assembly, and the owning feature when working in a part.
When you place the pointer on a command in the mini toolbar, the corresponding context is prehighlighted. For example, if you select a surface belonging to an Extrude feature and place the pointer on an Edit command, the Extrude feature is prehighlighted.
The Select from Parents command is available on the mini toolbar. This command gives you quick access parent objects from the selected geometry, on which you can perform subsequent actions.
The use of the ALT key is extended so that you can make a temporary selection outside of current selection filter scope which, by default, is geometry. For example use ALT to select features or components.
