NOTE The insertion point a block is defined with affects its placement as a custom
arrowhead on a dimension or leader. For information on changing the insertion
point of a block, see
Create Drawing Files for Use as Blocks (page 280).
If you use paper-space scaling, the scale factor is computed before applying it
to the arrowhead size value.

Control Dimension Text
You can control the placement of dimension text, arrowheads, and leader
lines relative to the dimension and extension lines.
Fit Dimension Text Within Extension Lines
Dimension text and arrowheads usually appear between the extension lines
when there is enough space. You can specify how these elements are placed
when space is limited.
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
Modify/New Dimension Style dialog box, 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.
