Autocad Commands arrays & LineType

      Places point objects or blocks at measured intervals on an object

Command                       : MEASURE enter

Select object to measure  : select an object

<segment length>/Block : specify a distance

      Places point object at the specified interval along the selected object, starting at the endpoint closest to the point used to select the object.

         Creates multiple copies of object in a given pattern.

Command : ARRAY enter

Select objects : select object(s) to array

Rectangular or Polar array(R/P)<current>: enter an option or press enter

          Creates an array defined by a number of rows and columns of copies of the selected objects.

Number of rows(—)<1>      : enter a non-zero integer or press enter

Number of columns(—)<1> : enter a non-zero integer or press enter

Unit cell or distance between rows(—) : specify a distance

Distance between columns (—)           : specify a distance

         The base point of the selected object is taken as the lower – left corner, and the object is arrayed in the first quadrant.

           Creates an array defined by specifying a center point about which the selected object is replicated.

Base/<Specify center point of array> : specify a point(1)

Number of items                               : Enter a positive integer or press enter

Angle to fill(+=ccw,-=cw)<360>       : Specify an angle or press enter

A positive value specifies counterclockwise (ccw) rotation. A negative specifies clockwise (cw) rotation.

OR

Angle between items(+=ccw,-=cw)      : specify an angle

Rotate objects as they are copied?<Y> : enter y or n or press enter

 Moves and rotates objects to align with other objects.

 Objects can be moved,rotated and scaled to align them with other objects. Source points are added to the objects you want to align,and destination points are added to the objects you want the source objects to be aligned to.You can add up to three pairs of source and destination points to align an object.

Command: ALIGN

Select objects : select the object which you want to align

Specify 1st source point : select SP1

Specify 1st destination point : select DP1

Specify 2nd source point : select SP2

Specify 2nd destination point : select DP2

Specify 3rd source point or <continue>: enter

Scale objects to alignment points?(Yes/No)<current>:

            Creates an ellipse or an elliptical curve.

Command : ELLIPSE enter

Arc/center/Isocircle,<Axis endpoint 1> : specify a point,value, or an option.

          The isocircle option is only available when the style option SNAP is set to isometric. Toggling of isoplane can be using the F5 key or CTRL E.

                 Defines the first axis by it’s two endpoints. The angle of the first axis determines the angle of ellipse. The first axis can either be major or minor axis of the ellipse.

Axis endpoint 2                        : specify a point

<other axis distance>/Rotation : specify a point, enter a value or enter r

               Rotation defines the major axis to the minor axis ratio of the ellipse by rotating a circle about the first axis. Entering 0 defines a circle.

Rotation around the major axis : specify a point or enter a value(0 – 89.4 degrees)

            Creates an elliptical arc. The angle of the first axis determines the angle of the elliptical arc. The first axis can define either the major or the minor axis of the elliptical arc.

<Axis endpoint 1>/isocircle/center : specify a point, enter value or enter an option

Axis endpoint 1 – defines the start point of the axis.

Axis endpoint 2                         :  specify a point

<Other axis distance>/Rotation : specify a point, enter a value or enter r

             Rotation defines the major axis to the minor axis ratio of the ellipse by rotating a circle about the first axis. Entering 0 defines a circle.

            Creates an infinite line.

Command : XLINE enter

Hor/Ver/Ang/Bisect/Offset/<from point> : specify a point or enter an option.

         Specifies the location of the infinite line using a point through which it passes.

Through point : specify the point through which you want the xline to pass or press enter to end the command

        Creates a horizontal xline passing through a selected point.

Through point : specify the point through which you want the xline to pass or press enter to end the command

           Creates a vertical xline passing through a selected point.

Through point : specify the point through which you want the xline to pass or press enter to end the command.

          Creates xline at a specified angle.

Reference/Enter angle<current> : specify an angle or enter r

Enter angle specifies the angle at which to place the line.

Through point : specify a point

         Creates xline that passes through the selected angle vertex and bisects the angle between the first and second line.

Angle vertex point : specify a vertex point

Angle start point : specify a point

Angle end point : specify a point or press enter to end the command

        Creates a xline parallel to another object.

Offset distance or through<current> :  specify an offset distance enter t or press       enter

Select a line object: select a line, polyline, ray,or xline or press enter to end the                       command

Side to offset : specify the side

        Creates an xline offset from a line and passing through a specified point

Select a line object : select a line, polyline, ray,or xline or press enter to end the                          command.

Through point : specify the point through which you want the xline to pass

          Creates a semi infinite line.

Command       : RAY enter

From point      : specify a point

Through point : specify the point through which you want to ray to pass or press enter

AutoCAD draws a ray and continues to prompt for through points so you can create multiple rays. Press enter to end the command.

          Creates loads and sets linetypes

         LINETYPE defines line characteristics consisting of combinations of dashes,dots, and spaces. You can use LINETYPE to load linetype definations from a linetype library(LIN), make a linetype current or modify linetype scales. Although every drawing entity has an associated linetype, the only entities that are affected by it are lines,arcs,circles and polylines. All other entities are always drawn with continuous lines. The prompt is:

Command : LINETYPE enter

       Displays the load or reload linetypes dialog box, in which you can load selected linetypes into the drawing and add them to the linetype list.

      Deletes selected linetypes. Only linetypes that are not referenced in any way can be deleted. Referenced linetypes include BYLAYER,BYBLOCK and CONTINUOUS.

      Sets the selected linetype to be the current linetype.

          Sets the linetype scale factor

          The dash specifications in a linetype definition are in terms of drawing units.Since drawing units mean “inches” in some drawing and “kilometers” in others, a global linetype scale factor is provided for each drawing with default value of 1.0. LTSCALE command allows you to change this factor. The prompt is

Command : LTSCALE enter

New scale factor<default> :

         Respond to the prompt with scale factor greater than 7 for A4 size sheet.
