Indoor or Outdoor? Nothing magical for AutoCAD that I know of. Just use general drafting techniques with what regulations you have, some equipment manufacturers have part models, though they could be only for Revit/BIM. Outdoor not much really to do but check regulations for berm heights, structures, shooting benches, any target supports, permanent targets, etc. The rest is just drafting. Indoor you need bulletproof roof, floors and walls (usually concrete), ventilation, acoustics/soundproofing, bullet traps (should be able to get model/drawing/specs from manufacturer), lighting considerations. Something like AutoCAD MEP and Architecture toolsets might be more useful. You might also want some video monitoring, a moveable target system for indoor might be wanted. Each part of the world and particular locations probably have different requirements, so probably no magic button.

As I posted in the other similar thread, I have found for most cases both FLATTEN and FLATSHOT of very little use. Posted somewhere on here are some TOOLBAR MACROs, which IMO does a better job for not too complex drawings to simply get a lot of basic objects to Z=0, as well as LISPs using the same method of moving everything then moving them all back. Initially it was needed for LT, not sure if something better can be used for newer LT with LISP. I'll repost the other thread which gives more on FLATTEN more complicated objects. Performance helps for Large-Scale Z-Flattening (Z0) AutoLISP Routine? - AutoLISP, Visual LISP & DCL - AutoCAD Forums

The FLATTEN command explodes MLeader and does not work with dimensions.

When my workload allows, I'll give it a good run.

P.S.: The interface is available in both Spanish and English. If your operating system language is different, the voice messages will be read in English, but with the pronunciation of your language. If this is your situation and it bothers you, you should search the code for all the English phrases and translate them into your language. It shouldn't take you more than half an hour. You can also mute the speakers . Everyone can do what they think is best.

you're welcome. The 'secret' when going MDI is using vla commands only.

Hola de nuevo, Offsetea.mp4 Dejé una tarea pendiente en este hilo que intentaré cerrar. Adjunto una nueva versión de Offsetea . A continuación, explico el comportamiento y las opciones del comando. Partimos de una lógica de trabajo basada en el enfoque del código de Evgeny Elpanov. De hecho, esta lógica es más fácil de explicar en código que con palabras: proyectar un segmento entre dos vectores guía (definidos por los extremos del segmento y el punto que precede a cada uno de ellos) que se intersecan en un punto, que se convierte en el foco de la proyección. Al proyectar segmentos rectos, el resultado solo puede ser uno. Sin embargo, en el caso de segmentos de arco, ¿qué ocurre si reemplazamos el foco de proyección? En base a esto, se me ocurrieron dos opciones adicionales: el centro y el polo del arco. También consideré la posibilidad de añadir una tercera opción que permitiera al usuario especificar la ubicación del foco en pantalla. Sinceramente, no creo que esto sea útil (espero que al menos una de las otras dos lo sea ). Así, la funcionalidad del comando es la siguiente: - Selección del segmento de polilínea a proyectar: el comando solo funcionará si la polilínea está compuesta por 2 o más segmentos. Si el segmento seleccionado es recto , los vectores guía se definirán por sus extremos y el punto anterior de cada uno (es decir, los segmentos adyacentes). Si uno de los extremos del segmento es también un extremo de la polilínea, el vector guía para ese extremo será la normal a él. Si el segmento es un arco , los vectores guía predeterminados serán los mismos que para los segmentos rectos (propuesta de Evgeny). Sin embargo, aquí es posible cambiar el enfoque del enfoque secante de Evgeny (tecla '2') al enfoque radial (tecla '1') o al enfoque tangente (tecla '3'). En cuanto a las herramientas de control del segmento a proyectar, he implementado un ajuste al estilo GLAVCVS , limitado a los casos posibles para este comando: _end, _mid, _int, _cen, _nod, _ins, _nea. Este ajuste se puede activar o desactivar con F3. La relación entre la posición del cursor y el segmento a proyectar siempre será de seguimiento de segmento en los segmentos rectos. Sin embargo, en los segmentos de arco, puede ser de seguimiento de arco o de cuerda. Para alternar entre ambos, simplemente pulse TAB. El seguimiento de arco está activo mientras el cursor permanece entre los dos vectores de proyección. De lo contrario, cambia automáticamente al seguimiento de cuerda. La diferencia entre ambos radica, por lo tanto, en el comportamiento cuando el cursor se encuentra entre los vectores guía. Estos vectores guía se muestran en pantalla como dos líneas discontinuas rojas. Junto al cursor se muestra texto informativo en tiempo real: Para segmentos rectos (de arriba a abajo): la distancia de desplazamiento desde la ubicación inicial y la longitud del segmento. Para segmentos de arco: distancia de desplazamiento desde la ubicación inicial, radio del arco, longitud del arco y longitud de la cuerda. La visibilidad de esta información se puede activar o desactivar con la tecla "i" . Por último, puedes aumentar o disminuir el tamaño de los indicadores junto al cursor presionando las teclas '+' o '-'. En cuanto al rendimiento del comando, mientras escribía el código, descubrí una mayor variedad de casos de los que inicialmente había pensado. Si el objetivo principal era lograr el seguimiento del segmento de arco según la posición del cursor, creo que este código cubrirá aproximadamente el 90 % de los casos posibles. En los casos donde no sea posible el seguimiento del arco, se realizará a nivel de la cuerda. Espero que a alguien le resulte útil. Offsetea_v2.lsp

Did you try FLATTEN command?

I really haven't tested this : ;;; setvar on allopen (defun c:soa ( / aod var val) (vlax-for doc (vla-get-documents (vlax-get-acad-object))(setq aod (cons doc aod))) (setq var "ORTHOMODE" val (vlax-make-variant 0 vlax-vbInteger))(foreach doc aod (vla-SetVariable doc var val))) ;;; or with save (defun c:soas ( / aod var val) (vlax-for doc (vla-get-documents (vlax-get-acad-object))(setq aod (cons doc aod))) (setq var "ORTHOMODE" val (vlax-make-variant 0 vlax-vbInteger)) (foreach doc aod (vla-SetVariable doc var val)(vl-catch-all-apply 'vla-saveas (list doc (vla-get-fullname doc))))) ;;; show allopen plotstyle (defun c:saps ()(vlax-for d (vla-get-documents (vlax-get-acad-object))(vlax-for l (vla-get-layouts d) (if (not (eq (vla-get-name l) "Model")) (vlax-put-property l 'ShowPlotStyles :vlax-true))))) ;;; hide allopen plotstyle (defun c:haps ()(vlax-for d (vla-get-documents (vlax-get-acad-object))(vlax-for l (vla-get-layouts d) (if (not (eq (vla-get-name l) "Model")) (vlax-put-property l 'ShowPlotStyles :vlax-false)))))

Do you want step by step undo? I would just wrap it in the start and end of the lisp to have one undo. (defun c:foo () (vl-load-com) (setq doc (vla-get-activedocument (vlax-get-acad-object))) (vla-StartUndoMark doc) ; Begin Undo Group ;code (vla-EndUndoMark doc) ;End Undo Group (princ) )

Yes, it could use some more refinement, but plenty close for what I need right now, I would like to get this LISP working on Leaders as well. I did get some headway on drawing a multileader to length, but spent too much time on this already, I have a couple of quick projects at work to knock out, so probably get back to it next week. I also looked at exploding, didn't really seem to be much better. When time allows I will play some more.

Why shurg? Sorry if you're MP over on there. It can pass defun if they're done like so with defun-q: (defun-q foo ( ) (command "tilemode" 1) (princ)) (vl-propagate 'foo) The running (foo) in the other open drawings will set them to model space. So this is where I was hoping that my code earlier would work.

shurg.

This thread for RunAll by MP on the swamp wrote this. @BIGAL, that RunAll utility will process all open drawings without having to write a script.

I do know of this prograam that was on the swamp by MP over there. https://www.theswamp.org/index.php?topic=53912.msg586779#msg586779 Just thought that (vlax-for d (vla-get-Documents (vlax-get-acad-object)) would work for this.

That's not how vl-propagate works. it only passes variable and its value between all open drawings. here is how i used it passing VC and SZ between all open drawings. once ZAD is run in one drawing any other drawing you run ZAD in will zoom to the same xy location. it was good to look at old revisions. ;;----------------------------------------------------------------------------;; ;; Zoom Area Across Multiple Drawings (defun C:ZAD (/ a) (initget "Yes No") (setq a (cond ((getkword "\nRedefine Zoom Area? [Yes/No]: ")) ("No") ) ) (if (= "Yes" a) (progn (vl-cmdf "_.Zoom" "W" Pause Pause) (setq vc (getvar 'viewctr)) (setq SZ (getvar 'viewsize)) (vl-propagate 'vc) (vl-propagate 'sz) ) (if (or (= vc nil) (= sz nil)) (prompt "\nPlease Define Zoom Area") (vl-cmdf "_.Zoom" "C" VC SZ) ) ) (princ) ) like i said AutoCAD doesn't like to run one lisp across multiple open drawings. but its been awhile since iv used it. Maybe this would work? -- edit oops didn't hit post

You can get a list of currently open documents and change to any of those documents. But your lisp will stop. Not sure and have mot tested using a script with this method. The one thing you must do is re do the current document list each time you change dwg. (defun openblk (blkname / adocs) (setq acDocs (vla-get-documents (vlax-get-acad-object))) (vla-open acDocs blkname) (vla-activate (vla-item acdocs 1)) ) You could load the lisp and run for each dwg name. have a look at 1st line each item inside acdocs for dwg names. Then write a script. script maybe (load "openblk") (openblk "dwg1") ; do your thing Save Close (load "openblk") (openblk "dwg2") ; do your thing Save Close and so on Example (vlax-get (vla-item acdocs 1) 'name) = "section.dwg" the acdoc has property "Count" so know how many dwgs are open.

Just a comment, If you compare the length of using vertices against the length of the spline they are different. So that was why I was exploding the mleader and playing with adjusting say the arrow point. The code I posted for 2 point mleaders could be easily changed to work with 3 or 4 vertices, ie a straight segment Mleader. That is why I was looking at making a matching spline and adjust it till correct length with doglegend = 0.0. Just have to work out how to set tangential line start to spline. A when have time task.

Yup, that sounds about right... LISP generally cannot perform a function on another open drawing. In MHUPPs link Lee Mac explains it in there. The only way I've found you can do it is to make a script for example in Lee Macs Script Write or in Script Writer Pro and use that - the drawings have to be closed though
