How to select all DWG objects of a certain type in AutoCAD LT? (texts, circles...)

A - answer Starting in version 2024, AutoLISP can be used in AutoCAD LT, so you can create selection sets using filters with DXF codes, just like in full AutoCAD. These can be used both for grip selection and for selection at the "Select objects:" prompt in the middle of an AutoCAD editing command.

So for example:

  • Select all line geometry (lines, polylines, splines) in the current layout:
    (sssetfirst nil (setq ss (ssget "_X" (list '(0 . "*LINE")(cons 410 (getvar "CTAB"))))))ss
  • Select all green objects in the current layout:
    (sssetfirst nil (setq ss (ssget "_X" (list '(62 . 3)(cons 410 (getvar "CTAB"))))))ss
  • Select all texts starting with an uppercase "A":
    (sssetfirst nil (setq ss (ssget "_X" (list '(0 . "*TEXT")'(1 . "A*")(cons 410 (getvar "CTAB"))))))ss
  • Select all red circles and arcs in the Situation layer:
    (sssetfirst nil (setq ss (ssget "_X" (list '(0 . "CIRCLE,ARC")'(8 . "Situation")'(62 . 1)(cons 410 (getvar "CTAB"))))))ss

The ssget filters can also use AND, OR and NOT conditions, parentheses, greater/lesser, wildcard characters, X/Y/Z coordinate components, etc. See examples in other tips.
