    I have a lisp file which works well at present using -bhatch for hatching by selecting a point inside boundary (c_sand, c_conc etc..) see below.
    I am trying to add a section to ask for a "p" or "s" (yet to be written and either use the point hatch as shown or selet objects (hatch)

    I have written the section s_sand (directly below c_sand) but the scaling is failing.

    I presume the line:
    (command "hatch" "ar-sand" "hpscale" 0 "")
    is wrong, Im new to this so it may be something obvious.

    Any suggestions please

    full code:-

    (defun MyError (strErr)

    Remove the quotes for a variable.

    Code:
    Wrong
    (command "hatch" "ar-sand" "hpscale" 0 "")
    
    Correct
    (command "hatch" "ar-sand" hpscale 0 "")
