Creating multiple viewports issue

November 8, 2018

This subroutine can create ONE rectangular viewport (as a part of other main routine)


(Defun VportRET (/ Ang Diag Pt1 Pt2 Pt2Lay Ptmed)
(setvar "clayer" LayFIN)
(setq Pt1 (getpoint "\nSpecify first window corner: "))
(setq Pt2 (getcorner pt1 "\nSpecify opposite corner: "))
(setq Ang (angle pt1 pt2))
(setq Diag (distance pt1 pt2))
(setq PtMed (polar Pt1 Ang (/ Diag 2)))
(setvar "CTAB" Lay)
(if (/= 1 (getvar "cvport"))(command "_.Pspace"))
  (if (/= SCA "Add")
      (progn
        (setq Pt2Lay (polar '(0 0) Ang (* Diag (atof FattZoom))))
        (command "_.dragmode" "_auto")
        (setvar "osmode" 0)
        (command "_.-vports" "0,0" Pt2Lay)
        (setq Ent (entget (entlast)))
        (setq Entname (cdr (assoc -1 Ent)))
        (setq NumVP (cdr (assoc 69 Ent)))
        (command "_.zoom" "_w" "0,0" Pt2Lay)
        (command "_.mspace")

need to add option to create multiple viewports (more than one) depend of number given by user like it shown in a different subroutine (also a part of other main routine)

                  (if (>= vpno 2) ; Proceed to copy current viewport if 2 or more separate viewports desired
                    (progn
                      (while (<= lpno vpno) ; Check if viewport loop counter less than number of viewports desired

On this stage It's very complicated for me to do it because of different combinations of variables in these 2 subroutines

Can somebody help me to do it and add necessary addition to the first subroutine?

Any help will be very appreciated
