Change space

[Robert G. Collier]

I hope someone can help with this.

In LDD there was a command that allowed items in paper space to be put into model space (and scaled automatically). I believe it was under the express menu items. I found this command very useful for various tasks. Does Carlson have this command or something similiar?

SSX is now "selectsim" etc. so I'm guessing I just don't know the command line input.

Thx

If you are running Carlson over Acad, the keyin for that command is CHSPACE. Hope this helps. -bharris

Thanks it does

I am looking for a chspace lsp that will run in Intellicad.

I found the old version 1.0 from Australia back in 1992. It will work from Paperspace to Modelspace, but not from Model back to Paper.

Any help would be appreciated.

;;; DESCRIPTION
;;;
;;; CHSPACE allows entities that have been drawn in paper space to be moved to
;;; model space and visa versa. Tilemode must be set to 0 otherwise an error
;;; message is given and the program terminates. This program works by making
;;; a block of the desired entities and then inerting them, exploded into the
;;; desired space. Consequently it is easy to change the insertion point, and
;;; scale of the entities in the new space.
;;;
;;; To run, type: CHSPACE tilemode must be set to 0.
;;;
;;; Next select the entities you wish to change and a reference point (the
;;; default is 0,0,0). Then select the new reference point in the new space
;;; (the default is 0,0,0) and finally select the scale (default = 1).
;;; If there are no active viewports on screen, a message is given and the
;;; program terminates.
;;;---------------------------------------------------------------------------;


;;;---------------------------------------------------------------------------;
;;; Internal error handling.
;;;---------------------------------------------------------------------------;

; while this command is active...
(if (/= s "Function cancelled")

)
(setq S nil) ; Free selection-set if any
(setvar "CMDECHO" cm) ; Restore saved mode
(setq *error* olderr) ; Restore old *error* handler
(princ)
)

;;;---------------------------------------------------------------------------;
;;; dent (entype ss) e.g. (dent "LINE" ss1)
;;;
;;; dent (delete entity from selection set) is used to delete a specified type
;;; of entity such as "LINE" "CIRCLE" etc. from a specified selection set.
;;; The new selection set (minus the removed entities) is returned.
;;;---------------------------------------------------------------------------;

;;;---------------------------------------------------------------------------;
;;; actvp

;;; screen (other than the paper space one). If there is not an active

That CAD Girl has a real good webinar training film on this site under Downloads that addresses paper space and model space in Carlson/Intellicad. Goes into the functions that you are asking about.

The CHSPACE command was added to the 2012 version in IntelliCAD 7 and will be available shortly.
