Atarting to use or learn Lisp.

Presently I want to be able to do following.

  1. Click on point
  2. Enter 4 vaules of a steel structure.
    1. Orig. Thickness
    2. Present thickness
    3. Max Allowable % wastage/reduction i.e, 25%
    4. Drawing result to look like this for 1" orig Plate showing present thickness and wastage calculation - .75"(.25").  Highlight %wastage as follows- red when 25% wastage and orange when 18.75% wastage.
Anyone able to assist in writing this code?

Your input is quite vague. What to do with the clicked point? What should be drawn?

(defun C:STEELSTRUC ( / pt oth pth pct)
 (setq pt (getpoint "\nClick a point: "))
 (setq oth (getdist "\nSpecify orig. thickness: "))
 (setq pth (getdist "\nSpecify present thickness: "))
 (setq pct (getdist "\nSpecify percentage - reduction: "))
;now perform drawing and calculations, the hardest part...
;e.g.:
 (command "_LINE" pt (list (+ (car pt) oth) (cadr pt)) "")
 (princ)
)

See attached.  I hope this shows what final drawing might look like.

Arrows and numbers are shown.  Red and Green showing bad thickness readings.

Should red and orange in the first description (item 2. sub-item 4.) be red and green instead?  (Or should green things in the image be orange instead?)

How/where does the description's item 1. "Click on point" relate to the drawing?

We use Red and Yellow actually.  And would like to stay that way.

When I say "Click on Point" I mean insert reading and % wastage at that location. I.e .233"(27%)

Do you think a MACRO can make this work?

Like this -- "ask for Orig, ask for present measurement, click on drwing to insert following in right location then continue same with all other locations the. double click to end inserting":

    measurement" (meas./orig*100)%  i.e .750"(75%)  i.e. .818"(81%)

Where original is 1".   

Always calculated % -- 0% to 75% is red, 76% to 81% is green, % greater then 82% black.
