Possible to make selection like ENTSEL with just coords?

[stusic]

Hey all!

Is it possible to simulate an aperture selection area stemming from a variable containing a point coordinate, similar to the pickbox for entsel? I'm trying to use the trans function (confusing) to select a block based on a point picked in paperspace. I can find the correct viewport and activate it, still working on how to make the trans function work, but not sure how the selection would be made... Any ideas?

Cheers and thanks

Not sure of your application; this may, or may not be of use:

(defun _ssPickBox (pt / ratio)
  (ssget "_c"
         (mapcar '+
                 pt
                 (setq ratio (list (setq ratio (* (/ (getvar 'pickbox)
                                                     (cadr (getvar 'screensize))
                                                  )
                                                  (getvar 'viewsize)
                                               )
                                   )
                                   ratio
                                   0
                             )
                 )
         )
         (mapcar '- pt ratio)
  )
)

That's awesome! Yeah, I dunno if I could've come up with that one on my own Thanks.

Now to just figure out trans to work *correctly*...

Again, application dependent:

(trans <pt> 3 2)

[edit] - you can always use Utility Object in lieu of TRANS, if you prefer.

I tried using the trans method as you show, but it tranposes it incorrectly. From what I've read it seems it's using the wrong ucs...

I have never heard of the Utility Object (and don't really see much in my seaarch, but my google-fu might be off today).

My goal is to have an mleader in paperspace display block attribute information. I'm using a point they pick (as though they're selecting the start of an mleader) as the basis to find the block they're selecting. It seems like trans would work if I were just using this in plan view (WCS), but they're often in weird isometric views with various UCS's.
