21	modify draw tool bar (i) erase (ii) move (iii) copy (iv) offset (v) array       rectangular                     -to draw continuous rectangle      polar	e ¬ select object ¬ m ¬ speciy base point » drag the object to required place         or specify co-ordinate or specify distance along x and y co ¬ click where copying is required o ¬ enter distance ¬ for multiple line type m ¬ o ¬ specify two points by clicking to make it offset distance ar ¬ ar ¬ select rectangle » click on select object » specify row and column offset ¬ draw rectangle » ar ¬ click on select object » select object ¬ click on ‘choose both offset bottom’ » click on corners of one diagonal ar ¬ select polar » select object » select center by clicking on co-ordinates and then on the point on screen to be chosen as center » specify angles and number ¬
22	circle circle can be drawn by specifying center points, radius or it can be made to pass through three points	c ¬
23	rectangle	rec ¬ specify co-ordinates of corners or enter dimension or enter area and one dimension rectangle can be made at any angle by rec ¬ r ¬enter angle¬
24	to know distance, co-ordinate	select line » di ¬ click on starting point » click on end point
25	text style	st
26	to list area, perimeter etc of polygon	Li
27	LTS(LTScale)	Increase its value to see the centerline with dash and dot clearly.
28	O (enter) L (layer) C (current)/S (source)	To offset any object with the current layer or source object layer (object whose object is to be taken)
28	L	To draw line.
29	dimlinear	It is under annotation menu bar. After typing ‘dimlinear’ click on one end of line and then the other end and move mouse outward then the dimension appears along with the line.
30	scale with reference (draw two square; A=10 units and B= 10 units side)	sc Select the object (square A) Click at the corner of the square (to specify base point) Press r (for reference) Specify the reference length (click on the corners of side of a square A) Press p Specify new reference length (i.e. click on the corners of the side of a square B) Then square A turns into square B.
31	ts	Table style
32	d	Dimension style
33	Dim	Dimension style
34	St	Text style
35	T	To write text
36	Lead	Leader arrow
37	Breakline
38	A	Area measurement
NOTE: If scale is 1:96 then 96 size of auto cad is 1 size fo paper. if 3 mm is required in paper then in AutoCAD 3*96 size is used so that the output in paper when printed is 3 mm. extend beyond dim line (extension line height above dimension line) tick on the "fixed length extension line" dimensioning is done form dimensioning tool. design center>design center>home,kitchen.....>block
