Many factors, such as the size of extension line spacing and arrowhead size,
influence how dimension text and arrowheads fit within the extension lines.
In general, the best fit, given the available space, is applied. If possible, both
text and arrowheads are accommodated between the extension lines, no matter
what fit option you choose.
When creating new dimensions, you can choose to place text by entering a
coordinate or using the pointing device; this is known as user-defined text
placement. Alternatively, the program can compute the text position for you.
The options for automatic fitting of text and arrowheads are listed in the
Dimension Style Manager, Fit tab. For example, you can specify that text and
arrowheads be kept together. In this case, if there is not room for both between
the extension lines, they are both placed outside. You can specify that if there
is room for only text or arrowheads, then either text only or arrowheads only
are placed between the extension lines.
The following illustrations show how the program applies a "best fit" for
arrowheads and text.
If there is no room for text between the extension lines, you can have a leader
line created automatically. This is useful in cases where text outside the
extension lines would interfere with other geometry, for example, in continued
dimensions. Whether text is drawn to the right or the left of the leader is
controlled by the horizontal justification setting on the Text tab of the
Modify/New Dimension Style dialog box. Also, you can fit text and arrowheads
by changing their size.
Even if the arrowheads are outside the extension lines, you can have a line
drawn between the extension lines. This is called forcing an internal line and
is illustrated as follows.
