Using the Draw Orthogonal option

You can restrict cursor movement to the current horizontal and vertical axes so that you can draw at right angles, or orthogonally. For example, with the default 0-degree orientation (angle 0 at the "three o'clock" or "east" position), when the Draw Orthogonal option is enabled, lines are restricted to 0 degrees, 90 degrees, 180 degrees, or 270 degrees. As you draw lines, the rubber-banding line follows either the horizontal or vertical axis, depending on which axis is farthest from the cursor. When you enable the isometric snap and grid, cursor movement is restricted to orthogonal equivalents within the current isometric plane.

NOTE IntelliCAD ignores orthogonal drawing when you type coordinates in the command bar or when you use entity snaps.

To enable orthogonal drawing

1. Do one of the following:
• Choose Settings > Drawing Settings.
• On the Settings toolbar, click the Drawing Settings tool ().
• Type settings and then press Enter.
2. Click the Coordinate Input tab.
3. Click the Draw Orthogonal check box.
4. Click OK.

TIP To toggle orthogonal drawing on and off at any time, double-click the ORTHO settings on the status bar, click the Draw Orthogonal tool () on the Settings toolbar, or press F8.
