Text can be drawn as SINGLE LINE TEXT and MULTI LINE TEXT (1) DTEXT : DTEXT displays text on screen as it is entered. At the command prompt, enter DTEXT Justify / Style / < Start point> : Specify a point or enter an option. (2) MTEXT : MTEXT creates paragraph text. At the command prompt, enter MTEXT Attach / Rotation / Style / Height / Direction / < Insertion point> : Specify a point or enter an option. 

2. The MODIFY Menu The MODIFY Menu contains sub-menus or commands to modify the drawn object. 2.1 TRIM : TRIM command cuts the portion of the object, which extends beyond another object. At the command prompt, enter TRIM Select cutting edges : (Projmode = UCS, Edgemode = No extend) Select objects: Use an object selection method <Select object to trim> / Project / Edge / Undo : Select an object, enter an option, or press enter. 2.2 ERASE : ERASE is used for erasing or deleting the objects from the drawing. At the command prompt, enter ERASE Select objects : Use an object selection method. ● Other Methods of ERASING the objects : 1] Selecting a single object 2] Window Selection      A] Left to right selection window      B] Right to left selection window ( Crossing) 2.3 COPY : With COPY command one can copy set of objects to a different location. At the command prompt, enter COPY Select objects : Use an object selection method < Base point or displacement > /Multiple : Specif

DRAW Menu Contd... 1.4 POLYGON : At the command prompt, enter polygon Number of sides <current> : Enter a numerical value OR press enter Edge / <center of polygon> : Specify a point OR enter 1.5 ELLIPSE : Ellipse is a curve having major axis and minor axis with a center. At the command prompt, enter ELLIPSE Arc / Center / Isocircle / <Axis endpoint 1> : Specify a point OR Enter an Option 1.6 RECTANGLE : At the command prompt, enter RECTANGLE First corner : Specify point Other corner : Specify point 1.7 MULTILINE :  With the MULTILINE submenu, one can draw set of parallel lines. 1.8 POLYLINE : Concept of POLYLINE : When one draw with a polyline, one fill as if one is drawing with a LINE. A LINE can be drawn in 3-Dimensional [3D], but the POLYLINE is not. POLYLINE is a collection of single segments or arcs, which is treated as a single object. If one DRAW a POLYLINE, it will have 2 GRIPS only while the LINE will have 3 GRIPS.  Concept of GRIPS : Small squares and triang
