Explode Polylines
When you explode a polyline, any associated width information is discarded.
The resulting lines and arcs follow the polyline's centerline. If you explode a
block that contains a polyline, you need to explode the polyline separately.
If you explode a donut, its width becomes 0.
Explode Block References
If you explode a block with attributes, the attribute values are lost, leaving
only the attribute definitions. The colors and linetypes of objects in exploded
block references can change.
Explode External References
An external reference (xref) is a drawing file linked (or attached) to another
drawing. You cannot explode xrefs and their dependent blocks.
Modify Polylines
Change the shape and display of polyline objects with polyline editing options.
You can also join separate polylines.
You can modify polylines using PEDIT, the Properties Inspector palette, or
grips.
■ Move, add, or delete individual vertices
■ Set a uniform width for the entire polyline or control the width of each
segment
■ Create an approximation of a spline called a spline-fit polyline
■ Display noncontinuous linetypes with or without a dash before and after
each vertex
■ Change the orientation of text in a polyline’s linetype by reversing its
direction
Modify Polylines with Grips
NOTE
For general information about working with grips, see Modify Objects Using
Grips (page 207).
Polyline grips offer some grip-specific options, depending on
■ The grip’s location (vertex or midpoint)
