Creating a Move/Copy/Rotate/Mirror Command

t.brezinsky — Tue, 17 Nov 2020 20:45:33 GMT

Hi All,

I'm looking to create a command or tool similar to the express tool command Move/Copy/Rotate/(scale), but instead of being able to scale the object I'd like to be able to Mirror the object. I'm using AutoCAD 2021 and am VERY green to this sort of customization. Any info helps.

Thanks,

TB.

Assuming some grip location is appropriate as a basis for Move or Copy displacement and/or Rotation base and/or Mirror axis, are you aware that you can do all that with grip-editing, without the need for any command at all, whether native or custom?

I was not aware of that and I'm not sure what grip-editing is.

Well that was rather easy. Thanks for your help. Just back to my original question.. Is something like that able to be done and work like the express tool move/copy/rotate?

The express command uses a arx but there is a another close to it and by Autodesk. You could possibly patch that.

It may be the original idea looking at 1990.

No way to edit MOCORO anyhow.

Why you're using that command? What's the advantage of its usage? The reason I am asking is, that we may recommend you some other way to achieve that. Personally, I never found this command useful. It's too cumbersome for me.

[Some of the Express Tools are defined in .lsp files, so I was thinking maybe it would be possible to edit MOCORO to add a Mirror option somehow, But unfortunately, the MOCORO command is in an .arx file, which I don't think can be edited -- at least, I don't know how.]

I use MOCORO because it's continuous, most times I'm not moving rotating or copying from a grip, and I don't mind using the keyboard keys to switch the function of the command. I just thought if the mirror command could be added in somehow that would be a bonus. I am however open to new ideas...

As I suggested what I posted is maybe the 1st version of the command, you can use that and add on to it.

You need a front end something like this keep choosing till you exit or hit OK the way this is set up you click a choice and dcl closes do not actually need to pick OK its there more for repeat.

No way to edit the current command but could be imitated and possibly enhanced. Still not sure if I find the usage for this, but certainly closer to my idea of how such a tool should perform.

Differences from the original MOCORO:

(prompt "\rSpecify point for qmove or [MovE/Copy/Rotate/Align/mIrroW/Flip/Scale/Base] <eXit>: ")

;; command options by single key stoke, no need to confirmation by enter or space

;; commands not obvious:
;; default is QuickMove - without osnaps, ignores base-ref-point if specified
;; both M/E are for the same Move - a classic command with a prompt for base-ref-point if unspecified yet
;; Copy - single copy only with prompt for base ref point if unspecified yet (not possible make it multiple as original MOCORO)
;; I/W/F for Mirror
;; I for classic Mirror with 'Remove objects' prompt
;; W for Mirror with NO to 'Remove objects' prompt, F for YES option
;; Align and Mirror ignors&resets base-ref-point if already specified

Footnote: qmove isn't as q as I thought would be because can't have grread on 2nd point 😞
