Using some LISP to do the same thing, forces Y direction only in this case (change (0 1 0) where the 1 applies to (x y z) axis) but no changes to ortho state (removes need for error checking to return ortho state to what it was before running the LISP on 'escape'), looses the 'elastic band' though (command "_.stretch" (ssget) "" (mapcar '* '(0 1 0) (setq pt2 (getpoint))) (mapcar '* '(0 1 0) (setq pt3 (getpoint)))) I had a quiet start to the week yesterday, so had a look - using grread to switch X or Y axis is not really satisfactory without a lot of messing about - a quiet day yesterday so I did just that but not to a state to make it worth posting yet. Today 'they' want me to work, weirdos.

Just a comment re stretch, if you do F8 ortho on, select object to stretch, pick point then drag mouse it will go in desired direction X or Y. Then type distance. No code.

I made some comments on your code. It does work but could be made more efficient. However the main point it does work, and I'll often leave things at that rather than spending hours optimising code to save milliseconds. The 'nil' report is just the LISP telling you that there is no result from the LISP. You could put this at the end (princ) which makes the LISP exit quietly. You could see the LISP reporting something by putting for example 'a' as the last line. So some comments I'd make: (defun c:zoo () ;; I'd use (defun c:zoo ( / ) - easier to check if you have localised variables (if (setq a (entlast)) ;; OK, check there is a Last Entity (while (setq b (entnext a)) ;; after (entlast) there should be no entnext (setq a b) ) ;; Add comment here "End While" - longer codes makes modification easier ;; Add here what happens if there is no 'entlast' ) ;; Add comment here "End if" - as above (setq ent (entget a)) (setq po (assoc 10 ent)) (setq pt (cdr po)) ;; Could combine this line to the po line above (setq po (cdr (assoc 10.... ))) (command "zoom" "c" pt 50 "") ;; Add here (princ) to exit quietly (no 'nil' after ending the code) ) Following your code format I'd do something like this (defun c:zoo ( / a pt) ;; Localise variables in case other LISPS use the same (especially common ones like pt) (if (setq a (entlast)) (progn ; If 'a' found (setq pt (cdr (assoc 10 (entget a)))) ;; Get point (command "zoom" "c" pt 50) ;; Zoom to point ) ; end progn (progn ; if 'a' not found ;; If 'a' not found (princ "\nNo entity found") ;; Report that 'a' not found ) ; end progn ) ; end if (princ) ; exit quietly ;;change this to pt to see effect of LISP reporting something (zooming point) )

This is taking the above a little further, but is not as finished as I might want. The user can alter the direction before or after selecting the entities rather than selecting the direction and then the entities. I reckon if you are using grread in something similar you are wanting quite a complex solution, most users are happy with 'select an option and enter' to continue. A bit of work to do another time so show the rubber bands for the stretches and to add in object snaps, but I am just adding this in here as an example - I might get more chance to look at this another day.

Ah yes .. I've done this in the past with regrets .. hope you're doing well Lee!

just use toggle 'Create separate hatches'

Don't need Revit, there is programs out there, here in AUS, Strucplus is one that does structural detailing, there is plenty of rebar lisps out there and most can be used to make a BOM. Wiseys steel shapes will draw your steel sections and has section library's available for steel shapes from all over the world or you can make your own. Many users post here. Again do a Google yes may take a few goes to find something. At "forums/autodesk" search "reobar"

@mhupp The arrow key codes (char 37-40) - at least on my keyboard - only work in the context of the number pad when number lock of OFF. The separate arrow keys return nothing to grread; no code 2, no char. data.

@thekiki You don't need LISP to do this, Just use the Overline and Underline tools in the MTEXT Editor Tab:

Try this: (defun c:foo (/ o s) (if (setq s (ssget ":L" '((0 . "*TEXT")))) (foreach e (vl-remove-if 'listp (mapcar 'cadr (ssnamex s))) (setq o (vlax-ename->vla-object e)) (if (= "TEXT" (cdr (assoc 0 (entget e)))) (vla-put-textstring o (strcat "%%O" (vl-string-left-trim "%%O" (vla-get-textstring o)))) (vla-put-textstring o (strcat "\\O" (vl-string-left-trim "\\O" (vla-get-textstring o)))) ) ) ) (princ) )
