A little bit more (setq lay (cdr (assoc 8 (entget (car (entsel "pick object for layer")))))) (setq s (ssget "_F" p (list (cons 0 "line") (cons 8 lay))))

I have gone away from initget to using dcl's with radio buttons. It would make sense to highlight the button that has been previously picked so you just pick OK.

Sure .. change the ssget filter: (setq s (ssget "_F" p '((0 . "line") (8 . "yourlayer"))))

The main function (c:ProjectTopRegionPoints) will detect the 'top' region automatically. So it should work from a script.

Placing the points on the Z=0 plane actually makes more sense. They can then be used for snapping when arranging these furniture blocks in plan. Revised code: (defun KGA_Conv_Pickset_To_ObjectList (ss / i ret) (if ss (repeat (setq i (sslength ss)) (setq ret (cons (vlax-ename->vla-object (ssname ss (setq i (1- i)))) ret)) ) ) ) (defun KGA_Geom_ObjectMiddle (obj / ptBL ptTR) (vla-getboundingbox obj 'ptBL 'ptTR) (mapcar '/ (mapcar '+ (vlax-safearray->list ptBL) (vlax-safearray->list ptTR)) '(2.0 2.0 2.0) ) ) (defun KGA_List_DuplicateRemoveAllEqual (lst fuzz / ret) (mapcar '(lambda (a) (if (vl-every '(lambda (b) (not (equal a b fuzz))) ret ) (setq ret (cons a ret)) ) ) lst ) (reverse ret) ) (defun RegionPointList (reg / objLst ptLst) ; Reg as vla-object.

Hi, maybe this help. https://www.theswamp.org/index.php?topic=49892.0

By adding "@" should work, but is better to look to POLAR function instead. Also, take care to avoid interference with current auto OSNAP and conflicts with a localized version of AutoCAD/redefined commands. (command "_.LINE" "_non" point1 "_non" (polar point1 (* (/ -170.0 180.0) pi) 3860.0) "")
