N o t e s

1. At the prompt:
[Mtext/Text/Angle]:

If a t (Text) is entered , another number can be entered , but remember
if the dimension is a radius the letter R must be entered as a prefi x to
the new number.

2. If the response is a (Angle), and an angle number is entered the text
for the dimension will appear at an angle.

3. If the response is m (Mtext) the Text Formatting dialog appears
together with a box in which new text can be entered . See page 147 .

4. Dimensions added to a drawing using other tools from the Annotate/
Dimensions panel should be practised.
