Creating Features with 2D Sections
Sketched features using 2D sections do not require references to other geometry in the Creo+ model. Some examples of where 2D sections are used are:
• Base features, sometimes called first features. This type of feature must be the first feature created in the model, and be of type PRO_FEAT_FIRST_FEAT.
• Sketched hole features.
• The PRO_E_SWEEP_SECTION section of a simple sweep feature.
To create 2D sketched features, follow the steps outlined in the section
To Create Sketched Features Element Trees.

Note:
|
For 2D sketched features, you need not specify section references or use projected 3D entities. Entities in a 2D section are dimensioned to themselves only. A 2D section does not require any elements in the tree to setup the sketch plane or the orientation of the sketch. Thus, the PRO_E_STD_SEC_SETUP_PLANE subtree is not included.
