You can define basic elements of a Creo Parametric feature, such as section profiles, sketching planes, extents, and so on, based on the entities that you select on the active drawing.

For example, you can select a line entity on the drawing to define a sketching plane. This entity on the drawing represents a surface or datum plane in the part. AutobuildZ searches for the relevant surface or datum plane in the 3D part to be used as the sketching plane. It creates a surface or datum plane when no relevant surface or datum plane is found.

For a section profile, the entities that you select must belong to the same drawing view. You cannot use these entities to define any other element. The entities that you select for the section profile are validated depending on the type of feature you want to create. If validation fails, you must first correct the error in the section profile or reselect entities before proceeding with feature creation. AutobuildZ provides a number of automatic section profile fix options that allows you to correct errors in the section profile.

You can preview or highlight the feature elements in 3D model space in a secondary Creo Parametric window each time you select entities to define the feature elements, such as section profiles, sketching planes, depth up to reference surfaces for extruded features and holes, and just before creating the feature. In addition, these entities remain highlighted in the graphics window during feature creation.
