How do you handle command line prompting/looping and exiting for selection sets? ssget doesn't allow a prompt. Which way do you do it for selection sets that contain more than one item? Jamie Duncan Consulting - If you're not part of the solution, there's good money in prolonging the problem.
don't know what you mean by looping and exiting but a little routine I use for getting a selection set is: (defun adcf-GetSet ( prmpt / selset) (or(setq selset (ssget "I")) (progn (if prmpt(prompt prmpt)) (setq selset (ssget)) );prong ) selset ) I usually select items first then issue command(pickfirst =1) so I wrote this to work the way I'm used to, if theres' an existing set selected, it uses that, else if theres' a prompt string passed in, it issues that prompt then calls ssget. then if you want to filter for items there's this one: ;;; if an implied set exists it is filtered according to filter list and returned ;;; if not, if a prompt is supplied, the prompt is issued then ssget gets filtered set ;;; Get set filtered with prompt (defun adcf-GetSetFp (filterList prmpt / rtnset) (or (setq rtnset(ssget "i" filterList)) (progn (if prmpt(prompt prmpt)) (setq rtnset(ssget filterList)) );progn ) rtnset ) eg: (setq blkRefSet(adcf-GetSetFp (list(cons 0 "INSERT"))"\nSelect block inserts to mess with... ")) or (setq blkRefSet(adcf-GetSetFp (list(cons 0 "INSERT")(cons 2 "BlockName"))"\nSelect blockName inserts to mess with... ")) or simply (setq blkRefSet(adcf-GetSetFp (list(cons 2 "BlockName"))"\nSelect blockName inserts to mess with... ")) that's what the prompt function is for, but it means you have to have more than one line showing in your command line window Which way do you do it for selection sets no idea what you mean there, many selection sets have more than one item... hth Mark
ssget doesn't allow a prompt. Which way do you do it for selection sets Maybe I'm not understanding you. When I issue a (ssget) I get to pick as many objects as I want. -------------- Command: (ssget) Select objects: 1 found Select objects: 1 found, 2 total Select objects: 1 found, 3 total Select objects: Specify opposite corner: 2 found, 5 total Select objects: Specify opposite corner: 1 found, 6 total Select objects: Specify opposite corner: 1 found, 7 total Select objects: w Specify first corner: Specify opposite corner: 3 found (3 duplicate), 7 total Select objects: <Selection set: 3>
And if you wanna get specific, you can preface it with a princ or prompt. (princ "\nPlease pick some daisies... don't be greedy, and ONLY the daisies: ") (setq flowers (ssget))
Thanks for the replies, it revolves around something where the selection set is in the start portion of the while i.e. instead of: (while (not (setq flowers(ssget.... (while looper (prompt "\nSelect the daisies or the lupens or <Exit>: ") (setq flowers (ssget now say the user picks some flowers here and there, and then says, hmmm exactly which flowers was I supposed to pick, but now the prompt says 'Select Objects...' I like the functionality of getpoint for example where using initget you can control quite a few options. I guess it's just not possible to have near that kind of functionality with ".select" or ssget or whatever you use to select objects I would love to be able to set/reset the ssget prompt - but can't see a way of doing this. Just me wanting a nicer interface than just 'Select Objects...'

hah! no wonder (ssget "X" '((0 . "LUPENS"))) wasn't working! <g> hmm, didn't even remark on the wishful/wistfulness play... I'm running downstairs now to begin a spring cleaning....have a nice Easter DB -- Jamie Duncan "How wrong it is for a woman to expect the man to build the world she wants, rather than to create it herself." - Anais Nin (1903-1977)
Hmmm... how exactly is that a play on words? You mean like it would be wrong to say 'that was just wistful thinking'? I guess I'm not privy to Canadianglishisms. Amurricans say it both ways, I think. nice Easter Easter... Ahhh the good ol days, hiding candy for the kids. Then as they got older I spent hours and hours making up clues for an indoor treasure hunt. THIS year, my younger son is on a special diet trying to conquer his acne. Currently he's off most everything that might be considered easterlike. So I think it'll just be a day like any other. Maybe I'll do the treasure hunt with money at the other end. -doug
wistfulness+wishful = wishfulness -- Jamie Duncan "How wrong it is for a woman to expect the man to build the world she wants, rather than to create it herself." - Anais Nin (1903-1977)
Let's step outside of the box... You want a selection set, so you're using ssget, What about ssadd and entsel? (setq selset nil) (setq saywhat "\nSelect the Flowers of your choice or <exit>: ") (setq enty (entsel saywhat)) (While enty (if (= " " enty) (setq enty nil)) (if selset (setq selset (ssadd (car enty) selset)) (setq selset (ssadd (car enty))) ) ) (redraw (car enty) 3);highlight it (setq enty (entsel saywhat)) ) (command "regen");unhighlight -- Gary J.

Thanks Gary I knew I could go along those lines but enstel doesn't allow all of the nice things that ssget does (like windowing/crossing etc) -- Jamie Duncan "How wrong it is for a woman to expect the man to build the world she wants, rather than to create it herself." - Anais Nin (1903-1977)
