Difference by display style

[saitoib]

Hi all.

rectang 0,0 100,100

rectang 100,0 200,100

After creating the above

With the display style as 2D wireframe, execute the following Lsip and select each square

Two entities are selected for each.

If you change the display style to concept, execute test, and select each square

only one entity is selected.

Why is this?

Thank you.

(defun c:test ( / ent pts ss nn i id)
  (setq ent (entget (car (entsel))))
  (setq pts (mapcar 'cdr (vl-remove-if '(lambda (x) (/= (car x) 10)) ent)))
  (setq ss (ssget "CP" pts))

  (princ "\n")
  (princ (setq nn (sslength ss)))
  (setq i 0)
  (repeat nn
    (princ "\n")
    (princ (ssname ss i))
    (setq i (1+ i))
  )
  (princ)
)

Also if you select the secend (the right) rectangle? 😉

CP (and w c cw ..) are view-dependend object selection methods

and the visualstyle is part of the current view,

also ZOOM and PAN can change the result of your TEST!

2DWireframe(CPU)  works different to all other VisualStyles(GPU),

what you stumbled over is how it works.

EDIT::

>>" and select each square only one entity is selected."

Not on my side: The last drawn rectangle select both rectangles, but the left one just the left.

view-dependend object selection methods are nothing what you can trust.

@cadffm 

I would say that the basis for drawing is a 2D wireframe.
I understand.
Thank you very much.
