Dimensions

Dragging

When you drag a dimension, the text remains visible.

Extension Lines

When you dimension to a circle containing a center mark, but use the circle instead of the center mark as the reference, a gap exists between the center mark and the extension line.

Fractional Dimensions

Fractional dimensions created with the Dimension tool are displayed in a stacked orientation. You set the orientation (horizontal stack, diagonal stack, etc.) and the stack size percentage in Tools, Options, Document Properties, Dimensions under Fractional display.

For stacked fractional dimensions, set the following in Tools, Options, Document Properties, Units: Set Length units to feet & inches. Select Fractions. Select Round to nearest fraction.

See Dimensions Options in the help.

Locking

The pointer indicates that you can lock a dimension's orientation.

See Lock Dimensions in the help.

Snapping

When you place radial, diameter, or chamfer dimensions, they snap at 15° increments. Linear dimensions snap at 0.40 from the offset, and 0.25 thereafter. You can specify the snap distances for linear dimensions in Tools, Options, Document Properties, Dimensions under Offset distances.

To override the snapping behavior, hold down ALT while dragging a dimension.

Undo

If you make a change to a dimension (for example, if you insert a symbol into a dimension), you can undo the change.
