Dimensioning

Dimensioning

Dimensioning

(OP)
if i have a shape to which i would like to give a general dimension , like a square of side measuring 'a' units, what should i do as all the dimentioning tools actually gives the measurement but not only a symbol. I like to use this quite regularly so i am expecting a quick way for it.
     is there a command to draw the central x and y axis of any figure?

RE: Dimensioning

After selecting the 2nd point of your dimension, select Text or Mtext

i am interested to write the text with dimension style ...line with two arrows at the ends

RE: Dimensioning

You actually start dimensioning

Command: _dimlinear

Specify first extension line origin or <select object>: _endp of   { 1st point }

Specify second extension line origin: _endp of
  { 2nd point }



Specify dimension line location or
[Mtext/Text/Angle/Horizontal/Vertical/Rotated]: t
  { here you specify to modify the default dimension}



Enter dimension text <208.83>: A
{ The character A will be placed instead of 208.83}



Specify dimension line location or
[Mtext/Text/Angle/Horizontal/Vertical/Rotated]:
{ specify position of dimension line}


Hope this helps

RE: Dimensioning

You can use dimordinate to draw the central x and y axis of any figure but the drawback is you must place the centroid of the figure on the point (0,0). Then when you use dimordinate, you can show a zero dimension from the center. It is a great command for sheet metal dimensioning as well.

RE: Dimensioning

If you are going to dimension linear edges using general dimensions often, you might want to add an extra level of automation to the method Svanels suggested by using a LISP routine.  Try adding this to your Acad.lsp file:

(DEFUN C:TEXTDIM ()(COMMAND "DIMALIGNED" "" pause "T"))

You can then create a custom button and assign it the macro
^C^C_textdim.  The advantage is that it saves you three keystrokes/buttons (5 instead of 8) each time.  

Also, if you are going to be using the same letters repeatedly, you might want to create a LISP command for each letter and assign it a unique button:  

(DEFUN C:TEXTDIMA ()(COMMAND "DIMALIGNED" "" pause "T" "A"))

This cuts the number of keystrokes down to three.
