Insert value returned by lisp to drawing on screen

I'm using this code to measure distance with consecutive clicks. It is like the dist command but allows me to measure polylines (zig-zag), add predefined constants and insert a value form keyboard and the total (tot2) is displayed in a dcl window.

I need help to insert this value (tot2) in the drawing in a position that would be determined by clicking on screen.

This way I would eliminate the dcl window and the trouble to write the value (tot2) manually on the drawing.

I need help to add error traps as well.

 v 300.1.1prad
;cumulative distance
;this routine is just like the Autocad Distance command with the
;exception that it allows you to pick more than 2 consecutive points.
;the routine will display the cumulative distance and the distance
;between the last two points picked on the command line.
;it will add predefined constants and ask for values to add to distance measured
;and show results in a dcl window

You can use something like this to add a text value, based on a specified point.

(and (setq pnt (getpoint "\nSpecify Text placement point: "))
    (entmakex (list '(0 . "MTEXT")
                    '(100 . "AcDbEntity")
                    '(100 . "AcDbMText")
                    (cons 1 tot2)
                    (cons 7 (getvar 'textstyle))
                    (cons 10 pnt)
              ) ;_ list
    ) ;_ entmakex
) ;_ and

Hi alanjt , I get this error.

I just copied the code and pasted to the end of my lisp.

Specify Text placement point: ; error: bad DXF group: (1 . 15.472)

What does it mean ?

Try this instead:

(and (setq pnt (getpoint "\nSpecify Text placement point: "))
    (entmakex (list '(0 . "MTEXT")
                    '(100 . "AcDbEntity")
                    '(100 . "AcDbMText")
                    (cons 1 (rtos tot2 2 2))
                    (cons 7 (getvar 'textstyle))
                    (cons 10 pnt)
              ) ;_ list

Sorry about that. I had just assumed you had/would convert it to a string.

Try this instead:

 

(and (setq pnt (getpoint "\nSpecify Text placement point: "))
    (entmakex (list '(0 . "MTEXT")
                    '(100 . "AcDbEntity")
                    '(100 . "AcDbMText")
                    (cons 1 (rtos tot2 2 2))
                    (cons 7 (getvar 'textstyle))
                    (cons 10 pnt)
              ) ;_ list
    ) ;_ entmakex

Thanks Lee.

Thanks Lee.

No worries dude

Thanks Lee:) Works perfect.

Is text height managed by this ?

(cons 10 pnt)

Thanks Lee:)

 

Is text height managed by this ?

NO, that's the insertion point.

For textsize: (cons 40 (getvar 'textsize))

or whatever you like.

No, Textheight is set by your text style.

You can have an override using:

(cons 40 <height>)

Huu azahh!

Thanks again.

Just did this and got what I wanted :

(and (setq pnt (getpoint "\nSpecify Text placement point: "))
    (entmakex (list '(0 . "MTEXT")
                    '(100 . "AcDbEntity")
                    '(100 . "AcDbMText")
                    (cons 1 (rtos tot2 2 2))
                    (cons 7 (getvar 'textstyle))
                    (cons 10 pnt)
                    (cons 40 0.1)
              ) ;_ list
    ) ;_ entmakex
) ;_ and

Just for the record, if you specify the value instead of retrieving it from a variable, you can additionally call it like the following:

'(40 . 0.1)

Explanation of Alan's suggestion:

http://www.cadtutor.net/forum/showpost.php?p=258390&postcount=20

I need to add two features to the code below:

1. the text be visible along with the cursor before specifying "Text placement point" - so that I can see that the text does not overlap other objects nearby.
   
2. be able to rotate Text (obviously not with the rotate command after insertion)

(and (setq pnt (getpoint "\nSpecify Text placement point: "))
    (entmakex (list '(0 . "MTEXT")
                    '(100 . "AcDbEntity")
                    '(100 . "AcDbMText")
                    ;(cons 8 lay)
                     (cons 1 (strcat "(" Edit1 Edit2 ")" (rtos tot2 2 2) Edit3))
                     (cons 7 (getvar 'textstyle))
                     (cons 10 pnt)
                     (cons 40 0.08)
              ) ;_ list
    ) ;_ entmakex
) ;_ and

This would only be possible either through a grRead loop, or using the move command with a pause, or perhaps using pasteclip.

Don't forget about ACET-SS-Drag-Move. I only suggest this to allow the user the ability of being able to utilize OSnaps normally and avoid the annoyances of a right-click if using Move..Pause. However, it does require Express Tools to be loaded.
