coordinates
A sytem of numbers used to locate a betoken or object in a drawing.
In the Cartesian coordinate organisation 2 numbers x and y are used to describe the location of a point in the horizontal and vertical dimensions respectively. 3D CAD programs add the z coordinate which describes distance in the third dimension.
In the Polar coordinate system a point is described by a distance and an bending where 0° exends horizontally to the right.

cursor
The screen symbol or icon which represents the current mouse location relative to the drawing window or viewport. The cursor may appear as crosshairs or another symbol based on which control is active.

bend
A complex entity created by the definition of endpoints of spline curve sections. Notation, the type of curve you use determines the types of editing tools or functions that may exist performed on it. See as well Bezier bend

font
The typographic style belongings of text. Fonts may be drafting style (one line thickness) or typographic such every bit that existence used in this certificate. Fonts are ordinarily managed by the operating system, not the CAD program and tin can be hard to translate from i estimator to another or 1 CAD program to some other.

grid
A drawing tool which is normally a pattern of regularly spaced dots or lines which make the alignment and drawing of objects easier. A snap to grid tool constrains or locks all drawing to filigree points only.

group
A collection of objects which tin be manipulated as ane object.

handles
Run into object handles.

hatch
A complex object defined by a series of points or a bordering object such as a circle or polyline which fills the defined expanse with a repeating pattern of lines. Hatches have a calibration property which determines the size and density of the repeating pattern. See also fill.

layer
A property of any drawing object. Unremarkably objects are organized onto unlike layers for organazational purposes and ease of drawing, viewing and editing. Layers oftentimes can exist named and can have default colors or other properties associated with them. Vectorworks Layers have the added power to have associated properties of scale, view, and projection. These added properties of Vectorworks layers are like in office to AutoCAD paperspace.

leader
A line with an arrowhead and attatched text pointing at another object.

leader line
The line portion of a leader connecting the shoulder to an arrowhead.

line
A CAD object defined past ii endpoints.

line type
A property of any line, circumvolve, curve, or arc. Line type describes a repeating pattern of lines and spaces. Lines may be solid, dashed, alternate, etc. The additional property of line type calibration determines how ofttimes in a given distance a pattern of lines and spaces repeats. Scale may or may not exist affected by the scale of the drawing view.

line width
A property of any line, circle, bend, or arc. Line width describes how thick a line or other object appears on the the screen or on a printout. Unlike CAD programs employ dissimilar schemes for acheiving

line width.

pocket-sized axis
The shorter axis of an ellipse.

motion
A drawing editing tool which moves objects or selection sets to a new drawing location by changing all definition points by a given altitude.

nested
Objects inside of other objects. Symbols may be nested within other symbols. Drawing commands can be nested or executed while other cartoon commands are active. Macro programming objects tin exist nested in terms of their control structure.

object handles
In a windows CAD program the handles which announced when an object is selected. Handles often let objects to be stretched, rotated, or moved.
Note: in AutoCAD handles refer to arbitrary names assigned to each drawing entity in the drawing database so that macros and applications may refer to specific entities directly.

commencement
The distance between two objects. Offsets are often used to draw parallel lines or determine the location of a dimension. In AutoCAD a command which creates a duplicate of an object at a specified distance.

origin
The point in a drawing with the x,y coordinates of 0,0.

ortho
Brusque for orthagonal. Usually refers to objects placed horizontally or vertically within a drawing. Ortho fashion is a constraint which limits all drawing to regular 90° angles. In some CAD programs other ortho angles and modes may be set up.

pan
The process of altering the drawing view by moving the viewpoint laterally relative to the drawing.
polar coordinates
Run across coordinates.

polygon
A complex object composed of three or more than straight lines in a closed effigy. Polygons are treated differently past diffent CAD programs. Often a polygon is simply a closed polyline entity.

polyline
A complex object composed of two or more than lines, curves, or arcs which have face-to-face endpoints. A airtight polyline or polygon has its endpoints joined into a closed form. Polylines are more hard to edit than a course fatigued with individual line segments, but offers some advantages when editing or building surfaces and 3 dimensional objects.

primitive

real scale
Objects in a CAD plan a fatigued at full scale or ane:1. Meet scale.

redraw
The process by which the video display is updated cleaning upward any unwanted marks or construction points. See also regenerate.

reference points
Points associated with drawing objects which permit an object to be selected, grouped, and manipulated. Reference points are often not visible. Ane example is the reference betoken of a text line which is frequently establish at the lower left hand corner of the text line. To select a text entity it is oftentimes neccessary to click nearly this invisible point or include it within a selection window.

regenerate
The process by which the view updated from the drawing database cleaning up whatever unwanted marks or structure points. Similar but more comprehensive and fourth dimension consuming that a redraw. Annotation: on some CAD packages these processes are synonymous.

relative coordinates
Drawing coordinates which when manually entered are interpreted every bit relative to the last signal entered. In AutoCAD relative coordinates are entered by preceeding the coordinate pair with the @ sign such equally @2,3.

resolution
The clarity or caste to which individual elements tin can be discerned on a monitor or print/plot. Common monitor resolutions include 600×800 and 1280×1024 measured in pixels. Mutual light amplification by stimulated emission of radiation printer and plotter resolutions range from 300×300 to 600×600 dots per inch. Resolution of these devices determines how accurate a printout will be or how accurate an object volition appear on the screen. The bodily resolution of objects saved in the drawing database is ordinarily much higher to insure a high degree of accurateness. When drawing objects are viewed on screen or plotted their size and position is rounded to the nearest dot at the resolution of a given device.

rotate
A drawing editing tool which rotates objects or groups of objects based on a center of rotation and an angle.

rubberbanding
A feature of many CAD programs which shows how a line or other object will look earlier it is actually placed. An example is with the line control. A starting betoken is selected after which a line appears rubberbanded betwixt the first point and the cursor. Equally soon as another betoken is selected the actual line is drawn and the rubberband moves to the next betoken.

scale
1) An editing tool which changes the size of an object relative to percentage. Some objects can be rescaled to unlike percentages in the x and y directions.
2) The relative size at which a drawing is viewed on the screen or printed/plotted. Scale is oftentimes represented as a ratio where 1:one is full scale, ane:12 = 1″ =1′-0″, 1:24=one/2″=i′-0″ etc.

script
A list of cartoon commands which tin be typed in a text editor and so loaded and executed with one command. Different scripting methods are supported by different CAD programs. Scripts are useful for performing repetitive tasks such equally drawing setups.

selection gear up
One or more objects selected for activeness with a single command. Oftentimes items are selected this way by drawing a window around them or holding down the shift primal while selecting them individually.

shoulder
The horizontal part of a leader line.

snap
A drawing tool which locates points exactly by finding an existing point inside the drawing database which is closest to a point selected with the on the screen. Some common snaps are: snap to nearest point, snap to midpoint, snap to intersection of 2 lines, etc.

snap to grid
A drawing constraint which forces all points picked to fall on the currentl filigree.

stretch
An editing tool which moves some of the points which ascertain an object and leaves others.

trim
A drawing editing command which causes 1 object to end exactly at some other. Trim points are calculated mathmatically so they are exact. Some complex objects such as curves cannot be trimmed to.
symbol
A collection of drawing objects divers as a single complex entity. Defining and using symbols speeds drawing and makes drawing files more meaty. Symbols are as well called blocks (AutoCAD).

tangent
A line which intersects a circumvolve, ellipse or arc at only i signal. Tangent lines to Bezier curves define the shape of the curve.

toggle
A cartoon control or setting which is either on or off. Subsequent execution of the command reverses the country of the parameter. Ane toggle is the dispaly filigree command.

units
Units of measure represented by numbers in a CAD program. Usually units are inches or anxiety, but can exist anything from millimeters to light years.

vertex
A point defining the junction of a segment within a polyline or polygon.

view
The graphical representation of the geometry stored in the cartoon database which appears in the drawing window or viewport. A view has a centre point and a calibration or zoom. Multiple views of one drawing may be open in seperate windows or viewports simultaneously.

viewport
The window or frame within which a view of the drawing is visible. In some circuitous CAD programs viewports are considered complex objects and can exist placed in drawings. Many programs also support the apply of multiple viewports which can simultaneously bear witness different parts of the same cartoon. This is especially important when working in 3D.

zoom
The manner the view is changed by magnifying or reducing the epitome on the screen. Zoom scales the view simply and does non touch on the bodily size of drawing objects.
