poly line command

PolyLine Command:

Command: PL
PLINE

Prompts common to Line and Arc segments:

Close: Connects first and last segments to create a closed poly line.

Half width: Specifies width from the center of wide segment to an edge.

Width: Specifies width of next segment.

Points to remember while working with width and half width:
  • The starting width becomes the ending default width.
  • The ending width becomes constant for remaining segments untill you change the width again.
  • The starting and ending points of wide line segments are the center line of segment.
  • Typically, the intersections of adjacent wide polyline segments are beveled.
  • No bevelling is performed for non tangent arc segments, very acute angles, or when a dot dash line types are used.
Undo: Removes most recently created segment.

Prompts only for line segment:


Arc: Begins creating arc segments tangent to previous segment. 

Length: Create a line segment of a specified length at same angles as that of previous segment. If the previous segment is an arc, the new line segment will  be tangent to arc segment.

Prompts only for Arc segment:

Endpoint of Arc: Completes an arc segment. The arc segment is always tangent to previous segment of polyline.

Angle: Specifies the included angle of the arc segment from the start point. Entering a positive number creates counter clock wise arc segments. Entering a negative number creates clockwise arc segments.

Center: Specifies an arc segment based on its center point.

Note: For the Center option of the PLINE command, enter ce; for
the Center object snap, enter cen or center.
Direction: Specifies the tangent for the arc segment.

Line: Switches from drawing arc segments to drawing straight segments.

Radius: Specifies the radius of the arc segment.

Second pt: Specifies the second point and endpoint of a three-point arc.

How to draw objects faster with perfect precision in AutoCAD | Object snap| polar tracking | Tracking method | Direct distance entry

 Hello Friends, This blog covers topic basesd on object snap tracking, polar tracking, direct distance entry, tracking method for drafting drawing without any any errors at faster speed.  OBJECT SNAP TRACKING: Object snap tracking (F11) works when object snap option (F3) is kept on. object snap tracks various points of object such as end point, mid point, intersection of two objects etc. they are also used to draw parallel lines and perpendicular lines with to respect to a given object.  You can get object snap and object snap tracking option under drafting settings for which you can press "DS" in command box. below diagram shows all the snap points which Autotrack uses. While tracking any objects a "+" sign is displayed on tracking point with a green extension line with a "x" mark. POLAR TRACKING: In autoCAD ortho mode makes it possible to track in vertical or horizontal direction with increment angle as 0, 90, 180, 270. how ever we can set out increme...

Co-ordinate systems

Hello Friends,             This is my first blog on AutoCAD tutorials. I won’t waste time on overview of AutoCAD and its uses which everyone knows. I will start directly with Co-ordinate systems of AutoCAD.             Co-ordinates systems are not of more use left in recent versions but still knowledge of co-ordinate systems is important as this keeps your mind sharp.  ABOUT CO-ORDINATE SYSTEM:     If you want to make any object in autocad you have two options.  1. you can directly click at any know point or  2. you can specify co ordinates of the point in command box. CARTESIAN AND POLAR CO-ORDINATE SYSTEM: Cartesian co ordinate system works only on linear distance. it have 3 axis X,Y,Z. when u specify any point with (+ or -) sign it prompts autocad to move along positive axis or negative axis at a specified distance. while working in 2D drafting, ...
