Glossary
inscribed polygon A regular polygon whose vertices fall on a defining circle. See also
circumscribed polygon and regular polygon.
intersection Creating a polygon from the shared area of two overlapping polygons.
Intersection snap A snap that allows you to specify intersection points by clicking
near the intersection of two entities. See also 2-Point Intersection Snap.
irregular polygon A polygon whose sides or angles are of unequal length.
isometric grid A reference grid aligned along three major axes, instead of two. This
allows you to create two-dimensional drawings of three-dimensional objects. Because
perspective is not applied, the objects can be accurately dimensioned. See also Circular
Grid, Rectangular Grid, and Reference Grid.
join To connect a line, arc, or polyline to another line, arc, or polyline, forming a new
polyline.
Jump snap A snap that allows you to enter a point exactly on an entity at a specific
distance or percentage from it’s endpoint.
justification In AutoSketch, the alignment of text in relation to the basepoint.
Horizontally, text can be justified left, right, or centered. Vertically, text can be justified
top, bottom, or centered. Text justified “top right,” for instance, has a basepoint at the
top right corner of the text extent.
last point The previous point entered in the current command. Used for Relative
snap and lock modifiers.
layer An organizational structure in a drawing roughly equivalent to a sheet of mylar
in conventional overlay drafting.
layer description A detailed description of a layer. Layer descriptions have a maxi-
mum of 63 characters.
layer name The name of a layer. Layer names have a maximum of 31 characters.
layer state The setting that determines whether new entities are added to a specific
layer and whether or not entities on that layer are visible and/or editable. There are
four layer states in AutoSketch: current, editable, masked, and background. See also
current layer, editable layer, masked layer, and background layer.
leader A type of annotation consisting of a marker, one or more connected lines, and
text.
leader length In dimensioning, the length of the automatically generated line
segment between the text entity and the extension line.
leading zero Zero displayed before decimal point in decimal numbers less than one
(e.g., 0.250 vs. .250).
library See symbol library.
line A straight segment between two points.
line terminator In dimensioning, a marker used to identify the end of a dimension
line or leader.
linear dimension A dimension that measures linear distance. Linear dimensions
normally consist of a line with terminating markers, a line of generated text, and,
