Understanding 2-D Mode
You can use 2-D mode to create sketches of curves or sections for 3-D shape creation operations.
n
Toggle between 2-D and 3-D mode. Use icons in the status bar. – You must specify the 2-D mode sketch plane.
–
n
Polar grid control: Grid’s orientation angle. – Spacing in radial and angular directions.
–
n
Specify whether sketched entities snap to grid.

Use 2-D mode to create sketches. Configure the grid. Utilize the precision panel while creating sketches. Sketch a Line/Arc Chain. Sketch rectangles, circles, and arcs. Leverage guides to create the desired 2-D shapes.
Opening and Creating a Creo Direct Model
A model created within Creo Parametric opens in Creo Direct, and vice-versa.
n n
Create new part or assembly models. Use templates: English – Metric
Configuring the 2-D Grid
The configurable 2-D grid is a useful aid when creating sketches.

Cartesian grid control: Grid’s orientation angle. – Spacing in X and Y directions.

Understanding the Precision Panel
The precision panel provides feedback and enables you to add input while sketching an entity such as a line, arc, rectangle, circle, ellipse, or spline.

Understanding Selection
There are several ways to select geometry or entities for performing operations.
n
Two main types:
–
Select (no default) – Select (with default) Basic geometry and entity selection includes: Preselection – Individual selection – Query selection – Pick from List
