What is wrong?
« on: January 26, 2005, 12:04:50 PM »
I have a piece of code that inserts blocks.  I set a certian layer before insert and insert the blocks the reset the layer  but when I check the layers of the object I see that the last one inserted is on the old layer why?

If I take out the call to return to the old layer everthing is fine except that I am on the wrong layer now.  Here is a spot of code:

Code: [Select]

;;; ------------ Insert View Name Callout into Drawing
(defun INSERT_DETAIL_CALLOUT ( / ArrowDirectory DetailArrow DetailName Directory InsPoint LyrName OldAttDia OldClayer OldOsmode)

;; Set enviroment variables
(setq OldClayer (getvar "CLAYER"))
(setq OldOsmode (getvar "OSMODE"))
(setq OldAttDia (getvar "ATTDIA"))

;; Check to see if the Layer is already there
(setq LyrName "G-VIEW-NAME")
(if  (not (tblsearch "LAYER" LyrName))
(CREATE_LAYER)
)

;; Check to see if the detail is in the search path
(setq DetailName "DetailCallout.dwg")
(setq DetailArrow "DetailCalloutArrow.dwg")
(if (not (findfile DetailName))
(progn
(setq Directory (vl-filename-directory (findfile(getfiled "Locating Detail Callout"  "DetailCallout" "dwg" 8))))
(setq DetailName (strcat Directory "\\" DetailName))
)
)
(if (not (findfile DetailArrow))
(progn
(setq ArrowDirectory (vl-filename-directory (findfile(getfiled "Locating Detail Callout Arrow"  "DetailCalloutArrow" "dwg" 8))))
(setq DetailArrow (strcat ArrowDirectory "\\" DetailArrow))
)
)
;; Set layer to insert layer and insert block
(setvar "CLAYER" "G-VIEW-NAME")
(setq InsPoint (getpoint "Select Insertion Point:"))
(setvar "ATTDIA" 1)
(command "-insert" DetailName InsPoint "" "" "")
(command "-insert" DetailArrow InsPoint "" "")

;; Reset sys variables
;(setvar "CLAYER" OldClayer)
(setvar "ATTDIA" OldAttDia)
(princ)
)


I have run into this before but cannot remember how to get around it.

Thanks

My guess is that SETVAR speeds past the COMMAND functions so that the layer is set prematurely. Try inserting a loop like (while (> (getvar "CMDACTIVE") 0)) before SETVAR.
