CAED - Chapter No 4Editing Tools in AutoCAD 2 Text Book Text Book:Mastering AUTOCAD 14 By George Omura Course Outline is available at CAED course website.

CAED - Chapter No 4Editing Tools in AutoCAD 3 Chapter Outline Erase Oops Copy Move Fill Rotate Divide Measure Block Scale Mirror Stretch Extend Offset Fillet Chamfer Array

CAED - Chapter No 4Editing Tools in AutoCAD 4 Erase Command The ERASE command lets you delete selected entities from the drawing. Format:ERASE Select objects: You can easily erase just the last object you drew by responding to the "Select objects" prompt with "L". You can erase the previous selection set by responding with "P". The OOPS command can also be used to retrieve the last thing you erased.

CAED - Chapter No 4Editing Tools in AutoCAD 5 Erase Command Modify / Erase Submenu SelectErases multiple selected objects. SingleErases a single selected object. LastErases the last object created. Oops!Undoes the last Erase command.

CAED - Chapter No 4Editing Tools in AutoCAD 6 OOPS Command The OOPS command reinserts the object(s) deleted by the most recent ERASE or BLOCK command. Format:OOPS You can also use UNDO for a general method of reversing the effect of most commands

CAED - Chapter No 4Editing Tools in AutoCAD 7 Copy Command The COPY command duplicates one or more existing drawing entities at another location (or locations) without erasing the original. Format:COPY Select objects: /Multiple:first point or distance. Second point of displacement:Enter second point

CAED - Chapter No 4Editing Tools in AutoCAD 8 Move Command The MOVE command is used to move one or more existing drawing entities from one location in the drawing to another. Format:MOVE Select objects: Base point or displacement:Select a point or enter a displacement vector. Second point of displacement:Select a point.

CAED - Chapter No 4Editing Tools in AutoCAD 9 Fill Command The FILL command controls whether Solids, Traces, and wide Polylines are to be solid-filled or just outlined. Format:FILL ON/OFF : Controls the filling of multilines, traces, solids, solid-fill hatches, and wide polylines

CAED - Chapter No 4Editing Tools in AutoCAD 10 Rotate Command The ROTATE command can be used to rotate existing entities. Format:ROTATE Select objects: Base point:Enter a point. /Reference:

CAED - Chapter No 4Editing Tools in AutoCAD 11 Rotate Command f you respond to the /Reference: prompt with a numeric angle, this is taken as a relative angle (number of degrees) by which the selected objects will be rotated about the specified base point, from their current orientation. A positive angle produces counterclockwise rotation; a negative angle produces clockwise rotation. If you respond to the last prompt with R, you can specify the current rotation and the new rotation you want. AutoCAD prompts: Rotation angle : New angle:

CAED - Chapter No 4Editing Tools in AutoCAD 12 Divide Command The DIVIDE command lets you divide an entity into a specified number of equal length parts, placing markers along the objects at the dividing points. Format:DIVIDE Select object to divide: /Block: Valid objects that can be divided include arcs, circles, ellipses and elliptical arcs, polylines, and splines

CAED - Chapter No 4Editing Tools in AutoCAD 13 Divide Command You can select a single Line, Arc, Circle, or Polyline. If you enter a segment count within the valid range of 2 through 32,767, Point entities are placed along the object to divide it into that number of equal segments. You can request a specific Block to be inserted instead of the Point entities by responding to the second prompt with B. The system then prompts: Block name to insert: Align block with object? : Number of segments:

CAED - Chapter No 4Editing Tools in AutoCAD 14 Measure Command The MEASURE command allows you to measure an entity, placing markers along the object at intervals of the specified distance. Format:MEASURE Select object to measure: /Block: Markers are always placed on the object, regardless of the elevation settings.

CAED - Chapter No 4Editing Tools in AutoCAD 15 Block Command You can request a specific Block to be inserted instead of the Point entities by responding to the second prompt with B. AutoCAD then prompts: Block name to insert: Align block with object? Segment length:

CAED - Chapter No 4Editing Tools in AutoCAD 16 Block Command The Block must currently be defined within the drawing. If you answer Y to the Align block with object? prompt, the Block is rotated around its insertion point, and drawn tangent to the object being measured. After you answer these prompts, AutoCAD measures the object, drawing the specified Block where each pair of segments meet.

CAED - Chapter No 4Editing Tools in AutoCAD 17 Scale Command The SCALE command lets you change the size of existing entities. The same scale factor is applied to X and Y dimensions. Format:SCALE Select objects: Base point:Select a point. /Reference:Enter a number or R. If you respond to the /Reference: prompt with a number, this is taken as a relative scale factor by which all dimensions of the selected objects will be multiplied.

CAED - Chapter No 4Editing Tools in AutoCAD 18 Scale Command To enlarge an object, enter a scale factor should be greater than 1.To shrink an object, use a scale factor between 0 and 1. If you respond to the /Reference: prompt with R, you can specify the current length and the new length you want. AutoCAD prompts: Reference length : New length: Indicate the Reference length by pointing to the two endpoints of a line to be scaled. Specify the new length by pointing, or by dragging the object.

CAED - Chapter No 4Editing Tools in AutoCAD 19 Mirror Command The MIRROR command lets you mirror selected entities in your drawing. The original objects can be deleted (like a MOVE) or retained (like a COPY). Format:MIRROR Select objects: First point of mirror line:Enter a point. Second point::Enter a point. Delete old objects? :Enter Yes, No, or press. The mirror line you designate is the axis about which the selected objects are mirrored; it can be at any angle.

CAED - Chapter No 4Editing Tools in AutoCAD 20 Stretch Command The STRETCH command allows you to move a selected portion of a drawing, preserving connections to parts of the drawing left in place. Connections made with Lines, Arcs, Traces, Solids, Polylines, and 3D Faces can be stretched. Format:STRETCH Select objects to stretch by window... Select objects: While you may use any of AutoCAD's forms of object selection in the STRETCH command, you must use a window-style selection, either Crossing or Window, at least once.

CAED - Chapter No 4Editing Tools in AutoCAD 21 Stretch Command The last window specified will be the window moved by STRETCH. Objects can be freely added and removed from the selection set. Once the selection set is specified, STRETCH asks you: Base point: New point: And displays a rubber-band line attached to the base point you enter. After you pick the new point, all the chosen objects will be moved or stretched as appropriate. STRETCH behaves differently depending on the entity type it is examining. Endpoints of Lines, which fall within the box, are moved; endpoints outside the box are left unchanged.

CAED - Chapter No 4Editing Tools in AutoCAD 22 Extend Command The EXTEND command lets you lengthen existing objects in a drawing so that they end precisely at a boundary defined by one or more other objects in the drawing. Format:EXTEND Select boundary edge(s)... Select objects: /Undo: You can use any form of entity selection to define the boundary objects. Lines, Arcs, Circles, and 2D Polylines can serve as boundary objects.

CAED - Chapter No 4Editing Tools in AutoCAD 23 Offset Command The OFFSET command constructs an entity parallel to another entity at either a specified distance or through a specified point. You can offset a Line, Arc, Circle, or 2D Polyline. Format:OFFSET Offset distance or Through : Select object to offset:

CAED - Chapter No 4Editing Tools in AutoCAD 24 Offset Command To offset from a wide 2D Polyline, measure the offset distance from the centerline of the Polyline. Once the object is selected, it is highlighted on screen. Depending on whether you specified an offset distance or selected Through in the original prompt, you receive one of the following prompts: Side to offset: or Through point: The offset is then calculated and drawn. The selected object is de-highlighted and the Select object to offset: prompt reappears. Press to exit the command.

CAED - Chapter No 4Editing Tools in AutoCAD 25 Fillet Command The FILLET command connects two lines, arcs, or circles with a smooth arc of specified radius. It adjusts the lengths of the original lines or arcs so they end exactly on the fillet arc. The FILLET command rounds or fillets the edges of two arcs, circles, elliptical arcs, lines, polylines, rays, splines, or xlines with an arc of a specified radius. Format:FILLET Polyline/Radius/ :Enter P or R or Select two entities to fillet.

CAED - Chapter No 4Editing Tools in AutoCAD 26 Fillet Command Options PolylineFillets an entire Polyline, or those segments to which the current radius can apply. RadiusSets the fillet radius for subsequent FILLET commands. Select...Allows you to select a first and second Line, Arc, Circle, or Polyline segment.

CAED - Chapter No 4Editing Tools in AutoCAD 27 Chamfer Command The CHAMFER command trims two intersecting lines (or two adjacent segments of a Polyline) at a given distance from their intersection and connects the trimmed ends with a new line.

CAED - Chapter No 4Editing Tools in AutoCAD 28 Chamfer Command Different trim distances can be set for the two lines, and are retained with the drawing. If the specified lines do not intersect, CHAMFER extends them until they do, and then proceeds as above. Format:CHAMFER Polyline/Distances/ : Options PChamfers entire Polyline. DSets chamfer distances.

CAED - Chapter No 4Editing Tools in AutoCAD 29 Array Command The ARRAY command makes multiple copies of selected objects, in a rectangular or circular pattern. Format:ARRAY Select objects:Show what to copy. Rectangular or Polar array (R/P):

CAED - Chapter No 4Editing Tools in AutoCAD 30 Array Command For a rectangular array, AutoCAD asks for the number of columns and rows, and the spacing between them. The array is built along a baseline defined by the current Snap rotation angle set by the SNAP Rotate command. For a polar, or circular, array, you first supply a center point. Then you supply two of the following three parameters: The number of items in the array. The number of degrees to fill. The angle between items in the array. You can also rotate the items as the polar array is drawn.
