Looking for a LISP - area and perimeter

Hello Everyone,

I'm new on forum.

I search for a very simple LISP which inserts (on centre in object or bottom, no matter) text with AREA and PERIMETER from RECTANGULAR or closed LINES.

e.g. area - "1,23 m2" and perimeter - "2,45 m"

Best when I can select more objects and than for the all selected the text will be written.

And this function for the two parameter should be writen together. Not that I must first use one command than second.

The font height should be possible to change.

Precission should be: 0,001m or 0,01m.

Could anyone help me?

Sorry for my english

Thanks!

For 'closed LINES' use first Command: BOUNDARY => PolyLines .

And then try this :

(DEFUN C:AreaPer ( / ar coHt coDec eN i lStrA lStrP p pr pMin pMax osm sel sL strA strP ti uL ) ;  dec hT

Thanks very much!

Ist possible to change the scale?

e.g. I'm drawing in "mm", then use the LISP and it shows: "1000000 m2", it should be: "1 m2"

I modified the program.

Units of length must be set with the command: units ,

because their value is taken from the AutoCAD variable : (getVar "insUnits")

Thanks! Thanks! Thanks!

How can I change the font color?

How to change the position of text?

1 . This creates layers ; Find it :

(vl-cmdF "_.Layer" "n" "Area,Perimeter" "c" [color="red"]1[/color] "Area" "c" [color="blue"]5[/color] "Perimeter" "")

1 = red ;

5 = blue ;

Put what colors you like.

2 .

How to change the position of text?

Surface texts are inserted in the middle? Where do you put them? Attach a DWG example.

Or mode tag = justify ( middle left, center, middle , bottom right ) ?

Example in "Paint":

It is possible, but more complicated. How do with circles or arcs of a circle?

If the rectangle is tilted, rotated or irregular ?

You have right. It is complicated.

But I usualy use object like this:

Its possible to make second version of the LISP for me?

Thanks!

If you insist, look:

From what I've seen, you do not know AutoLisp. It would be good and you learn this programming language, is easy and very useful.

While working with AutoCAD, you always need programs to help you work.

PS :

Today I leave on vacation in the country for at least one week and I don't have internet there. So we hear after Easter vacation .

Thanks!

Happy Easter!

Thanks for the greeting.

Download the program again because I brought something useful.

Search these:

  (if (not (numberP hT)) (setq hT [color="red"]1.[/color])) ; Real
  (if (not (numberP dec)) (setq dec [color="red"]3[/color])) ; Integer

and put the values ​​that you consider the most common.
