shape, or by selecting a circle orpolyline after typing or picking the "E"option

get rotated with the angle
C "circular" array type in a circularpattern, you must indicate anglebetween items, angle to fill, andwhether objects get rotated with theangle

DIM Takes you out of the drawing editor and
into the semi-automatic dimensioningprogram built into AutoCAD. Will displaya Dim: prompt on the command promptline. To get back to the drawing editorand the Command: prompt, type the key.
DIM1 Same as above, but only allows onedimensioning command to be used, andthen takes you automatically back to thedrawing editor and the Command:prompt.
DIM
ALIGNED
Dimensioning sub-command:
Draws a linear dimension with thedimension line parallel to theselected dimension origin points.This lets you align a dimensionwith an angled line that is noteither exactly horizontal orvertical.
DIM
ANGULAR
Dimensioning sub-command:
Draws an arc and calculates theangle between two non-parallellines, and draws the text andarrowheads. Arrowheads are thestandard AutoCAD filledtriangles, regardless of yourdefined Arrow Block.

BASELINE Continues a linear dimension fromthe baseline (the so-called "firstextension line") of the previous orselected dimension. This is notfrequently used in architecturaldimensions. The spacing between
each dimension line is controlledby the AutoCAD variableDIMDLI ("Dimension LineIncrement"), which you should setat 0 normally, but if you use thebaseline command, you shouldreset to 1/8".
DIM
CENTER
Dimensioning sub-command:
Draws a pair of crossed lines atthe center of a circle or arc on the
current layer
DIM
CONTINUE
Dimensioning sub-command:
Continues a linear dimension fromthe second extension line of theprevious or selected dimension. Itis used to create a so-called"string" of dimensions. This isused quite a bit in architecturaldrawings.
DIM
DIAMETER
Dimensioning sub-command:
Draws a dimension through thecenter of a circle or arc,calculating the diameter, with oneof the arrow heads located at thepoint on the circle or arc which ispicked.
DIM
EXIT
Dimensioning sub-command:
Exits the dimensioning programand returns from the Dim: promptto the normal Command: prompt
DIM
HOMETEXT
Dimensioning sub-command:
Restores the text of an associativedimension to its default (home)location if you have moved it.

DIM
HORIZONTAL
Dimensioning sub-command:
Draws a horizontal lineardimension line
DIM
LEADER
Dimensioning sub-command:
Draws an a line or series of lineswith an arrow head (commonlycalled a "leader") to point to anobject to notate it. This commandwill also prompt you for the noteat the end of the leader line, but itwill allow only one line of text. Themost useful method of using thiscommand is to simply drawleaders between the object to benotated and text that you create
with the DTEXT command.
DIM
NEWTEXT
Dimensioning sub-command:
Permits changing text of anassociative dimension withoutexploding it. However, once thetext has been changed, thedimension will no longer beassociative.
DIM
OBLIQUE
Dimensioning sub-command:
Adjusts the obliquing angle of alinear associative dimensionsextension lines. Useful indimensioning isometric drawings.
DIM
ORDINATE
Dimensioning sub-command:
Draws the X and Y coordinateswithin a box with a leader lineattached to the point, for a
selected point. Automaticallycalculates the coordinates.
DIM
OVERRIDE
Dimensioning sub-command:
Overrides the dimension variablesettings on a selected dimension.
DIM Dimensioning sub-command:

DIM
REDRAW
Dimensioning sub-command:
Redraws the viewport, just like theregular REDRAW command.
DIM
RESTORE
Dimensioning sub-command:
Makes a dimension style current
DIM
ROTATE
Dimensioning sub-command:
Draws a linear dimension with thedistance measured origin points,but with the actual dimension lineset at a different angle.
DIM
SAVE
Dimensioning sub-command:
Saves the currently set dimensionvariables under a dimension stylename for future retrieval throughthe RESTORE command.
DIM
STATUS
Dimensioning sub-command:
Lists all dimension variables withtheir current status.
DIM
STYLE
Dimensioning sub-command:
Switches to a new Text Style forall future dimensions.
DIM
TEDIT
Dimensioning sub-command:
Allows moving text in associativedimensions without having toexplode the dimensions.
DIM
TROTATE
Dimensioning sub-command:
Allows rotation of the text ofseveral associative dimensions atonce.

to the original block. In the case of adimension or hatch pattern that hasbeen exploded, their parts go back tothe 0 layer, and are assigned the logicalcolor (BYBLOCK) regardless of thelayer they were drawn on. In the case ofan exploded polyline, it loses any widthit may have had.

OSNAP Enables points to be precisely locatedon reference points of existing objects.This is the so-called "Running Mode" ofOSNAP, which sets selection method torun continuously until set to NON (none)or until overridden by selecting another"Interrupt Mode" OSNAP method fromthe cursor menu. Combinations ofOSNAP methods can be used byselecting a series of options separated
by commas. For instance, if you want otalways pick either endpoints orintersection points when locatingendpoints of lines, you would issue the
command as follows:

3DFACE Draws flat planes in 3D space witheither 3 corners or 4 corners (3 sided or4 sided flat planes). These are used tohide objects behind them in space tocreate the illusion of a solid object.3DFACEs can also be shaded using theSHADE command, in which case theentire plane takes on the color assignedto its edges. Normally (without using theHIDE or SHADE commands, 3DFACEsare transparent, which means thatobjects behind them in space are visiblethrough them, and they appear as"wireframes."
I ("Invisible") this is used bytyping in the letter "I" just beforepicking a corner point for the3DFACE, and it will make theedge of the 3DFACE drawn fromthat point to the next one"Invisible" (that is, it will not beshown as a line on the drawing).This is important when joiningseveral 3DFACEs together tocover a complex, multi-facetedsurface, where you do not wantthe "seams" of the 3DFACEs toshow in the final drawing. Thevisibility of edges of 3DFACEscan further be turned on or offby the AutoCAD variable"SPLFRAME." WhenSPLFRAME is set to 1 ("on"),both edges which have beenmade "Invisible" as well asnormal, visible edges are shownon the drawing. WhenSPLFRAME is set to 0 ("off"),Invisible edges are not shown.The purpose of sometimeswanting to see invisible edges is
