Perspective view of the object and switch to plan view( centred to the object at distance viewed in perspective view)

[pyou]

Hi

Strange request here.

When i look at specific object in perspective view, would it be possible  to switch to plan view, but centred on object of interest at the same distance as viewed in perspective view? Currently i just type in ''plan'' , but it gives overall view with all detail in drawing.

I am not sure if there is a  settings/command in autocad or i would need a lisp command to do this. Any ideas, please?

Not sure exactly as I don't play with views except in layouts as plan production, but it sounds like what you want as a sequence.

 

Plan Zoom Center pt scale

 

The scale will be a number you may find that one number gives a reasonable zoomed in view. 

The pt will be a point selected in your isometric view. (setq pt (getpoint "\nPick a point ")) you could make a little defun that gets you the point, so run that 1st. 

 

(defun c:pt ( / )
(setq pt (getpoint "\nPick point "))
)

 

So the sequence becomes.

Dbl click isometric view

pt

dbl click plan view

plan z c pt 1000

Something like this, but it's not working perfect, Any suggestions how to improve?

Seems not to work properly with 3dpolylines, lines and polylines. Is there a way to click on polyline and that point to become a centre of object or something similar alternative? On other objects it seems to work as i want.

 

Thank you

 

Lisp:

(defun c:ZoomToPlanView (/ obj obj_center)
  ;; Prompt the user to select an object
  (setq obj (car (entsel "\nSelect an object to view in plan view: ")))
  
  ;; Check if the user selected an object
  (if obj
    (progn
      ;; Get the object's center point
      (setq obj_center (cdr (assoc 10 (entget obj))))
      
      ;; Switch to plan view
      (command "_.plan" "")
      
      ;; Zoom into the object
      (command "_.zoom" "_c" obj_center 1.0)
      
      (princ "\nObject displayed in plan view and zoomed.")
    )
    (princ "\nNo object selected.")
  )
  (princ)
)

When using zoom c, I never found it to use 1.0, I think you need to do manually and see what Zoom C returns in your zoomed in/out view I doubt it will be 1.0.

 

Current dwg zoom C = 55.797 not 1.0 value changes, zoom e,  Zoom c = 163.78

still not found solution for 3dpolylines,lines and polylines. any help,please?

And if you use the command DVIEW?

((lambda ( / e_sel e pt_sel)
  (princ "\nSelect an object.")
  (cond
    ((setq e_sel (entsel))
      (setq e (car e_sel) pt_sel (osnap (cadr e_sel) "_near"))
      (command "_.dview"
        e ""
        "_points" "_none"
        (list (car pt_sel) (cadr pt_sel) 0.0)
        "_none"
        (list  (car pt_sel) (cadr pt_sel) 1.0)
        ""
      )
    )
    (T (princ "\nNothing selected."))
  )
  (prin1)
))

Thank you Tsuky! it seems sometimes when i click on MText or Text its just isolate selected text and getting error

''object snap not allowed here.
Requires direction and magnitude angles separated by a comma.
; error: Function cancelled.  

 

Would it be possible to incorporate _pnod  to pick a pointcloud point and have same principal what dview does?

I have specified the code for this task.

But you can add for exemple at line 5:

((lambda ( / e_sel e pt_sel)
  (princ "\nSelect an object.")
  (cond
    ((setq e_sel (entsel))
      (setq e (car e_sel) pt_sel (osnap (cadr e_sel) "_near,_ins,_nod"))
      (command "_.dview"
        e ""
        "_points" "_none"
        (list (car pt_sel) (cadr pt_sel) 0.0)
        "_none"
        (list  (car pt_sel) (cadr pt_sel) 1.0)
        ""
      )
      (sssetfirst nil (ssadd (car e_sel)))
    )
    (T (princ "\nNothing selected."))
  )
  (prin1)
))

 

For pnod I can't incorporate this, but without control of the return of "pnod" you can try this

((lambda ( / pt_sel)
  (command "_.ID" "_pnod" pause)
  (setq pt_sel (getvar "LASTPOINT"))
  (command "_.dview"
    ""
    "_points" "_none"
    (list (car pt_sel) (cadr pt_sel) 0.0)
    "_none"
    (list  (car pt_sel) (cadr pt_sel) 1.0)
    ""
  )
  (prin1)
))

Thank you Tsuky, Works excellent.
