A computer program can carry out extremely complex tasks specific to a particular drawing problem.

It is a command to unite the object as one entity for easy insertion of the same object.

Information or data about a drawing object which can be hidden or appear in the drawing as text. Often this information can be extracted from the drawing and used in a spreadsheet or other program

  Marks a point on a graph by how far along and how far up it is.

Are points determining the path and shape of a Bezier curve.

A drawing tool which limits drawing to a particular point, line or angle. Some common constraints are snap to grid and ortho.

It is a system of numbers used to locate a point or object in a drawing.

It is a drawing exchange format created by Autodesk. An ascii text file format is used in describing drawing data and settings to translate drawings between programs and formats.

It is a common command which break objects apart into their component pieces.

It is a common command which break objects apart into their component pieces.

It is a complex object defined by a series of points or a bordering object such as a circle or polyline which fills are with solid color.

It is the typographic style property of text and may be drafting style (one line thickness) or typographic such as that being used in this document.

It is a drawing tool which is usually a pattern of regularly spaced dots or lines which make the alignment and drawing of objects easier.

These are used to mark the end points of lines.

It is the shorter axis of an ellipse.

A curve defined by endpoints, tangent lines, and control points at theends of the tangent lines. Altering the length and angle of tangent linesalters the shape of the curve.

It is usually with an arrow indicating the direction and distance of a drawing dimension.

It is where the drawing being displayed.

It is where the drawing being displayed.

It is the central part of a CAD drawing. A sequential list of all objectswhich exist within a drawing along with all parameters and definition points.

It is the central part of a CAD drawing. A sequential list of all objects which exist within a drawing along with all parameters and definition points.

It is the central part of a CAD drawing. A sequential list of all objects which exist within a drawing along with all parameters and definition points.

It is the process by which the video display is updated cleaning up anyunwanted marks or construction points. See also regenerate.

It is a property of any line, circle, curve, or arc.

It is an objects in a CAD program a drawn at full scale or 1:1.

These are associated with drawing objects which allow an object to beselected, grouped, and manipulated.

It is a collection of drawing objects defined as a single complex entity.

It is a diagonal line which connects points on two intersecting objectssuch as an angled corner.

It is a class of drawing commands used to modify drawing entities orobjects.

It is a class of drawing commands used to modify drawing entities or objects.

It is a drawing editing command which causes one object to endexactly at another.

These are objects inside of other objects. Symbols may be nestedwithin other symbols.

It is the distance between two objects and are often used to drawparallel lines or determine the location of a dimension.

It is the process of altering the drawing view by moving the viewpointlaterally relative to the drawing.

These are either of two coordinates, the radius or the polar angle, thattogether specify the position of a point in a plane.

It is a complex object composed of two or more lines, curves, or arcswhich have contiguous endpoints.

It is an editing command which creates multiple copies of objects bycopying them around a center point for a given angle.

It is the process by which the view updated from the drawing databasecleaning up any unwanted marks or construction points.

It is a drawing tool which locates points exactly by finding an existingpoint within the drawing database which is closest to a point selected on thescreen.

It is the clarity or degree to which individual elements can be discerned on a monitor or print/plot.

It is a list of drawing commands which can be typed in a text editorand then loaded and executed with one command

It is a drawing constraint which forces all points picked to fall on thecurrent grid.

It is a line which intersects a circle, ellipse or arc at only one point.Tangent lines to Bezier curves define the shape of the curve.

These are units of measure represented by numbers in a CAD program. Usually units are inches or feet, but can be considered to be anything from millimeters to light years.

It is an editing tool which moves some of the points which define anobject and leaves others.

It is a point defining the junction of a segment within a polyline orpolygon.

It is the window or frame within which a view of the drawing is visible.

It is the way the view is changed by magnifying or reducing the imageon the screen.
