Sets the options for the Dynamic Input Heads-Up Display (HUD).
Access
Choose 
Options. Then open the Sketch tab of the Application Options dialog box, and click Settings.
- Enable Pointer Input
-
When active, the starting point for a sketch element is displayed as Cartesian coordinates (X and Y values) in the value input boxes near the cursor. Disabling Pointer Input turns off the coordinate display of the starting point of a sketch element.
- Pointer Input options
-
Use to switch the starting point for a sketch element between Cartesian and Polar coordinates.
- Cartesian Coordinates
-
When selected, the starting point of a sketch element is displayed with X and Y values relative to the sketch origin of X = 0, Y = 0. This is the default setting.
- Polar Coordinates
-
When selected, the starting point of a sketch element is displayed with length (L) and angle (A) values relative to the sketch origin of X = 0, Y = 0.
- Enable Dimension Input where possible
-
When active, values are entered using a combination of both regular Cartesian and Polar coordinates depending on the type of sketch element being drawn. Dimensions are automatically placed on sketch geometry when the TAB key is used to toggle between value input fields.
When this setting is disabled, values are entered using Delta X and Delta Y Cartesian coordinates only. Polar coordinates cannot be used. Dimensions are not placed on sketch geometry even when using the TAB key to toggle between value input fields.
Dimension Input options
- Cartesian Coordinates
-
When selected, both positive and negative Cartesian X and Y coordinates are entered. The values are calculated based on the last pick point.
- Polar Coordinates
-
When selected, values are entered using a combination of regular Cartesian and Polar coordinates depending on the type of sketch element being drawn. The values are calculated based on the last pick point. This is the default setting.
Persistent Dimensions
- Create dimensions when inputting dimension value
-
When selected, persistent dimensions are automatically created and placed on sketch elements using the values entered in the value input boxes. The TAB key must be used to toggle through the value input fields.
When disabled, no persistent dimensions are placed on sketch geometry.
Note: Persistent dimensions may be quickly toggled on and off while sketching by clicking Sketch tab
