Setting Up the Drawing Environment

To set up the drawing environment you can apply unit, drawing bounds, grid, and snap settings. You can store these settings in template drawings.

Setting the Units Format

Drawing units

When you create a drawing, decide what units to use. You can set one drawing unit to represent one millimeter, one centimeter, one meter, and so on.

Linear and angular units

You can set the format for entering and displaying linear and angular units. You can also set the accuracy level by specifying the number of decimal places.

Linear units can have formats such as Decimal Units, Imperial Architectural Inch and Feet, Imperial Engineering Inch and Feet, Fractional Units, and Scientific Exponential Notation.

Angular units can have formats such as Decimal Degrees, Degrees/Minutes/Seconds, Grads, Radians, and Surveyors Quadrant Angles.

To set the units format:

1. Click Tools > Options (or type UnitSystem).
1. Click Tools > Options (or type UnitSystem).
1. Click Application menu > Preferences (or type UnitSystem).
2. In the dialog box, click Drawing Settings .
3. Expand Unit System.
4. Set options.
5. Click OK.

Setting the Drawing Bounds

Use drawing bounds to:

• Define the bounds of a drawing
• Control where entities can and cannot be drawn to prevent entities from being drawn outside a specified region
• Define the extent of the grid display

Usually drawing bounds are relative to the paper size when printing a drawing. Bounds checking is turned off by default; there is no restriction as to where entities can be drawn.

To set drawing bounds:

• Click Format > Drawing Boundary (or type DrawingBounds).

Setting the Grid and Snap

Grid

The grid is a pattern of evenly spaced dots that serve as a visual distance reference. The grid is not part of the drawing file and does not appear in the printed output.

You can set the grid to span the graphics area or limit it to the extents of the drawing.

To show or hide the grid:

Snap creates a set of invisible magnetic points that force the pointer to move in even increments. Snap constrains the points you can choose with the pointer to the snap grid you define.
