5.4.3 DRAW FILLET
The DRAW FILLET command is used to draw arc fillets between 2 existing
entities. An arc fillet is an arc segment tangential to 2 entities.
COMMAND FORMAT
#DRAW FILLET modifiers :Ent x1 x2 [:Ent x1 x2] ...
Any valid combination of 2 entities can be identified. The entities may be
cpoint, line, arc, string or polygon. If one of the entities is a string or
a polygon, the segment closest to the identifying digitise is used for the
fillet construction.
The entities should always be identified in anti-clockwise order with
respect to the required arc, as the arc segment will be constructed anti-
clockwise starting at a tangent to the first entity and ending at a tangent
to the second entity. ( See fig. 5.30 and 5.31 ).
Some cases such as an arc fillet between 2 other arcs can have up to 8
possible solutions. The solution returned will be dependent on the locations
used to identify the 2 entities. The location used to identify each of the
two entities should be in the approximate vicinity of the point where the
arc fillet will intersect each entity. ( See figs. 5.32 to 5.34 ).
The default case is to trim the 2 construction entities to the point of
intersection with the arc fillet. This is only valid for arcs or lines or
in the case of a string entity, if the segment identified is the first or
last segment of the string.
MODIFIERS
LAYER Requires a layer number. This will override the current
active layer.
DEPTH Requires a depth number. This will override the current
active depth.
RADIUS A real value defining the arc fillet radius.
NOTRIM If this modifier is entered, the 2 construction entities
will not be trimmed. ( See fig 5.35 ).
HARDFONT Indicates a hardware line style will be entered.
.STYLE One of the predefined line-styles, a value between 0 and 15.
.THICKNESS Line thickness, a value between 1 and 5.
SOFTFONT Indicates a software line style will be entered. For a full
description of the SOFTFONT option, see the documentation
for the command DEFINE SOFTFONT.
ATTRIBUTE Used to enter one or more attributes associated with this
entity. For a full description of the ATTRIBUTE option, see
the documentation for the command ADD ATTRIBUTE.
