Chapter 2 Important Concepts
■
Marker —A marker is a special entity that notes a specific point in a draw-
ing. For more information, see the chapter titled “Markers,” which begins
on page 241.
■
OLE Object —An OLE object is a special entity created in one application
and embedded into another. When you double-click a linked OLE object,
Windows opens the source application that created it and loads the asso-
ciated file. When you double-click an embedded OLE object, the source
application opens within AutoSketch—that is, its toolbars, menus, and so
on, temporarily replace AutoSketch’s. For more information, see “Using
the Clipboard &OLE” in online Help.
■
Picture —A raster image is a picture or bitmap that can be imported and
placed in the drawing. AutoSketch treats the raster image like most other
entities, allowing you to move, scale, or duplicate it as needed. For more
information, see “Tracing in AutoSketch” in online Help.
■
Polygon — A polygon is a closed polyline that can contain a fill pattern.
Use a polygon when you need to know the area of an enclosed region or
when you need to fill an area with a hatch pattern, bitmap fill, or a solid
color. For more information, see the chapter titled “Polylines, Polygons, &
Curves,” which begins on page 137.
■
Polyline —A polyline is a multi-segmented line AutoSketch treats as a
single entity. When a polyline is closed, it becomes a polygon. Use a
polyline in situations where you need to know the total length of a series
of connected segments.
■
Symbol —A symbol is a group of entities that AutoSketch treats as a single
entity. Symbols can be stored in libraries for use in multiple drawings. For
more information, see the chapter titled “Symbols,” which begins on page
167.
■
Text —A text entity can be any size and can use any TrueType font. It can
be rotated at any angle. For more information, see the chapter titled
“Working With Text,” which begins on page 211.
