Uses of Lenthen Command

Short Cut:-LEN+enter:

• This command is used to extend or trim the length of a line and an object.
• If we apply positive value it extend the value of object as mentioned and it work similar to extend.

        Ex:- (5) extend value of line by value 5.

• If we apply negative value it trim the value of object as mentioned and work similar to trim.

        Ex :- (-5)trim value of line by value 5.

Steps to open lengthen command:

Modify (go to ->)lengthen(if short cut command not known).

It has four sub tools

• Delta
• Percentage
• Total
• Dynamic

Delta:-

• Short cut command:-DE+enter

• By this command we can extend or trim the value of an object
  Range{-x to +x}.

• If we apply value in (+)x it will extend the line (+)x direction.
• If we apply value in (-)x it will trim the line (-)x.
• In this we doesn't have to specify the point on object line. we can click anywhere on the object line and it will increase or decrease the value.
• If point of click is before center point than above part get extend or trim as per value given.
• If point of click is after center point than tail part get extend or trim as per value given.

Percentage:-

• Short cut command :- P+ enter

• Similar to delta command.
• It will increase or decrease the value of line as per specified value in percentage.

Total:-

• Short cut command:- T+enter

• It will also extend and trim the value of object.
• But in this when we apply value positive to the object and if point of click is before center than we get mentioned value before center and if click after center than we get mentioned value in tail portion.

        Ex:-total line length 100

        T+enter

         20+enter

        We get 20 as per click of point.

• And if we apply negative value to the object and if pont of click is before center than we get value as per our requirement and if click after center than we get required value in tail portion.

         Ex:-total line length 100

         T+ enter

         We get 80 as per click of point

Dynamic:-

• Short cut command: -dy+enter

• By this we can have dynamic shorting and lengthening of an object.
• We can also enter free value by using this sub tools.
• When we apply this command it ask 1^st to select 1^st point and than is ask to select 2^nd point and if point of click applied i.e before of after and also value entered is positive or negative we get the result.

Although lengthen command in AutoCad is similar to trim and extend but it has certain advantage over above command

• Trimming and extending of an object by using same command only we have to specify value.
• By using trimming command we can only trim intersect or overlapped area only
• For using extend command, we have to specify some boundaries or target to the object.

[To repeat last command again and again use “space bar”.]

Also we can check the value of object which we increased or decreased by using DLI command.
