change default ARC command

jessicapaula8QYSS — Thu, 08 Feb 2024 14:41:10 GMT

Hello!

I would like to change my default arc type from 3 point to start, end direction. I rarely use the 3 point type arc, and am constantly using the start, end, direction arc. I have to select this type of arc from the ribbon every single time I wish to use it, because when I press the space bar the command reverts back to 3 point. Would someone have an LSP command line that works? I tried to make my own but couldn't.

Hi,

you can customize your ribbon by command CUI.

I prefer to change the property to keep the last choice, but you can also re-order the buttons.

found an lsp line that worked:

(defun C:ARCSED() (command "_.arc" pause "E" pause "D" pause))

If you ever use CTRL to toggle the direction, remove the last pause. Also, to make it cleaner, add (princ) at the end.

(defun C:ARCSED() (command "_.arc" pause "E" pause "D") (princ))

You can actually do that, without making a different command name, by undefining the regular Arc command and making a new definition under the same name. Put this into acaddoc.lsp so it will happen in every drawing you create or open:

(command "_.undefine" "ARC")
(defun C:ARC ()
(command "_.arc" pause "_e" pause "_direction")
(prin1)
)

Then you don't need to remember to use the different command name for that option sequence. And Enter/space to recall the latest command will get you the same, and ARC as auto-completed when you type in the first letter or two, and the Arc icon in the ribbon, and the A default alias. You can still use the native Arc command allowing other than that specific option sequence, when you want to, by typing it in with a preceding period to force use of the native command instead of your custom definition -- .ARC.

[Ordinarily I would spell out option names completely as I did with "_direction" here, rather than use abbreviations. That's for the future possibility that later enhancements to a command might introduce other options that might start with the same letter, making that ambiguous. But in the case of the End option in ARC, and either End or Endpoint in some other commands, the full word is taken as an object-snap call for picking the next point. So the _e alone is necessary here.]
