When you add dimensions to your sketch, the default dimension text height is 12 points. You can change the text height by using the arrows in the Dimension text height field of the Sketcher Options dialog box. The dimension text is independent of the current sheet size and zoom settings; that is, the text remains at the size you chose regardless of the apparent size of the dimensioned feature.
In addition, you may want to change the number of decimal places to match the dimensions of the feature you are creating. You can use the Decimal places field to control the number of decimal places displayed in each dimension. To reduce clutter while editing a sketch, you can use the Show dimensions option to hide the dimensions. Dimension customization options apply to the sketch you are working on and are stored along with the sketch. When you create a new sketch, ABAQUS/CAE uses the most recent settings to determine the height of dimensions and the number of decimal places.
