Dash Type, Miter Limit

Chapter 2 Graphics Tutorial Figure 2. 19. Miter Limit W W = line width L = miter length L Miter limit = maximum ratio of L/w = 1/sin (a/2) If the angle at which lines join is such that this limit is exceeded, the lines are joined with a beveled join, rather than a mitered one. The purpose of the miter limit is to prevent objectionably long spikes when lines join at small angles. The default miter limit is 10, which results in beveled joins at angles of less than about 11.5 degrees. You can set any desired miter limit with the SMLT (Set Miter LimiT) command. This command has the following format. SMLT limit-value; Here are some representative limit-values and the corresponding angles at which the line join type switches between mitered and beveled. limit-value appox. angle 2 60 3 39 4 29 5 23 6 19 7 16 8 14 9 13 Dash Type By default, the STRK command strokes paths with solid lines. However, you can also use a predefined pattern of alternating black and white to stroke paths. This makes it possible to stroke paths as dashed lines. You can also define your own dashed line patterns. The DPAT (select Dash PATtern) command selects one of PRESCRIBE's ten predefined dash patterns, or one of 10 dash patterns that you can define yourself. This command uses the format: DPAT pattern-number; 2-22

Miter Limit
Miter limit = maximum ratio of

=

)
If the angle at which lines join is such that this limit is exceeded, the lines are joined with
a beveled join, rather than a mitered one.
The purpose of the miter limit is to prevent objectionably long spikes when lines join at
small angles. The default miter limit is 10, which results in beveled joins at angles of less
than about 11.5 degrees.
You can set any desired miter limit with the
SMLT
(Set Miter LimiT) command. This
command has the following format.

Here are some representative
limit-values
and the corresponding angles at which the line
join type switches between mitered and beveled.
Dash Type
By default, the STRK command strokes paths with solid lines. However, you can also
use a predefined pattern of alternating black and white to stroke paths. This makes it pos-
sible to stroke paths as dashed lines. You can also define your own dashed line patterns.
The DPAT (select Dash PATtern) command selects one of PRESCRIBE’s ten predefined
dash patterns, or one of 10 dash patterns that you can define yourself. This command
uses the format:
