Select Hatch Pattern by Scale and pattern

I'm having an issue with this select Hatch lisp. See comments in code where the error is occurring.

(cons 41 patScale) is at fault.

It fails when selecting solid hatches. Others seem fine.

Thanks in advance.

Change your SSGET to this:

(ssget "X"
      (vl-remove 'nil
	  (list	(cons 8 layer)
		'(0 . "HATCH")
		(cons 2 patname)
		(if (/= "SOLID" patname)
		  (cons 41 patscale)
		)
		(cons 62 laycolor)
		(cons 410 (getvar 'ctab))
	  )
      )
)

Change your SSGET to this:

Thank you very much.
