[Plugin] Mirror

TIG

Today I noticed when I mirror a component the mirrored copy gets "Scale definition" active. When click to reset it rotates 180 degree, when choose to scale the original now gets "Scale definition"?

The component instance will be scaled '-1' in the selected direction[s]. Resetting the scale should revert to the original scaling...

And may be this is the cause of my troubles with the components getting unique! I did a lot of models with the Mirror Selection - now I just copied instead of mirror and components don't convert to unique!

hello

maybe i've missed something, but I tried mirror 3.5 with sketchyphysics and it won't do the mirror operation... Once the sketchyphisics has been removed no problem... I had thought I had understood that 3.5 fixed this (amongst other things)... shame as it's a great tool.
(using v7 on a vista platform)...

thanks anyway to TIG for all the time & trouble.

This is a known bug caused by SketchyPhysics rewriting the code of some of the API's own Group class, which is used by Mirror. I'm not sure what the issue is.
Perhaps if you bring pressure to bear on the SketchyPhysics side they could fix their code to stop the problem!
AS SketchyPhysics loads after Mirror could you try renaming 'Mirror.rb' as 'zMirror.rb' so it loads afterwards -perhaps what SP breaks will stay OK this way and hopefully SP will still work...

Thanks for yr speedy reply... I tried the workaround, but alas to no avail ! I guess you're right, we have to ask the SP guys to fix there stuff ! Thanks anyway, & meantime their stuff is out & yours is in as totally indispensable (I don't understand why the gogol people haven't put in a mirror command as a basic standard tool like in any other cad program !).

Thank you!I have downloaded it.

Hi TIG,
Thank you for sharing all of your wonderful talents. This + the imagetrimmer.rb are very nice.

I haven't had time to read this whole thread, so sorry if this issue has been mentioned before:
On my machine, when I have the toolbar for Mirror open, and I double-click a component or group to edit - it can take about 4-5 seconds to actually open the group or component. This was killing me until I tried just closing the mirror36.rb toolbar button. I downloaded the .rb file from this thread just tonight. I thought to close the toolbar and the problem went away. I would have no idea why. I have a shortcut assigned and don't need the toolbar anyway.

Make sure you have v3.6 installed...
It might be because there's a context-menu too ?
To stop the toolbar being made at all you can simply move the button file 'MI.png' out of the ../Plugins/ folder and then there will be no toolbar as it only gets made IF the button's png is found.
To stop the context-menu item appearing you can open the 'Mirror.rb' file in Notepad.exe or another equivalent plain text editor [NOT a wordprocessor] and near the end of the code around line #376 there's this block of text

UI.add_context_menu_handler do |menu|### v3.5 TIG
      #if Sketchup.active_model.selection
        #menu.add_separator
        menu.add_item("Mirror Selection"){Sketchup.active_model.select_tool(MirrorTool.new)}
      #end#if
   end#do menu###

change it so the UI.add..., menu.add... and end#do... lines all start with a #, thus

#UI.add_context_menu_handler do |menu|### v3.5 TIG
      #if Sketchup.active_model.selection
        #menu.add_separator
        #menu.add_item("Mirror Selection"){Sketchup.active_model.select_tool(MirrorTool.new)}
      #end#if
   #end#do menu###

now there'll be no context-menu.
Having done this you'll only have the main Plugins menu item 'Mirror' to shortcut to.

Incidentally if you'd like the tool to appear in say the 'Tools' menu and be named 'Mirror' you can simply edit line #370

UI.menu("Plugins").add_item("Mirror Selection"){Sketchup.active_model.select_tool(MirrorTool.new)}

to read

UI.menu("Tools").add_item("Mirror"){Sketchup.active_model.select_tool(MirrorTool.new)}

Thanks a lot TIG.
I was in a (rather) large file, and perhaps it was just a glitch happening with the machine/RAM/etc.
Everything seems fine today (with or without toolbar showing)... I do appreciate the info, however, as there are times I wish I could modify these things in some rubies.

I confirm that circles get exploded in some cases.
Not when they are free standing, but when they are part of a face, like on top of a cube, yes.
Pretty annoying.

TIG

Mario

I've tested what you say and can't get a circle or arc to 'explode' after mirroring
Are you using the latest version?
Can you supply a skp where you do get this issue, so that I can test it...

TIG

Your gif doesn't auto animate ??
A face with edges should copy and mirror OK, loose edges/arc == edges ??

jorge2011

"Your gif doesn't auto animate ??"
you click on the image

when the circle mirror with your face, does not exploit the circle
When mirror only the circle, the circle is exploited

I know BUT it looks just like any other image so why would I want to click on it at all
A gif can auto-animate... so it's obvious what it is.

Sr TIG, see this exampler
see this example.
Mirrors edge face ( copy good)/ edge mirrors only (copy explode edge)

jorge2011

sorry but I do not understand what you say.
Posted there again animated giff

TIG

NOW it animates automatically... before it didn't!
You 'attached' the first one but the second one was 'placed-in-line as a linked-image'

TIG

It's the way that Sketchup itself works...

Try this manual test.

Make a circle.
Group it - including its face in the selection.
Copy the group.
Edit it, you find that the circle remains a circle.

Now make another circle.
Group it - this time excluding its face from the selection.
Copy the group.
Edit it, you find that the circle is now is pieces.

Because Mirror has to make a group and copy it to do the scaling/mirroring then it will fail to keep the circle-ness of the circle if it has no face[s] selected with it in the group - exactly as occurs when you do it by hand

It's a shortcoming in Sketchup not Mirror...

Yep, 3.6, downloaded today.
Skp attached; just a box with circle on top.
Mac related issue ?
update : tested it on my Doze 7 vm, same problem.
update-2 : sorry, indeed mirroring the perimeter does explode it, mirroring the round face works fine. (I was working with hole in steel plates, so mirror before punch)

hi folks,
I have been using mirror.rb v3.6 without problems for a while... until today where i'm using SU8 on a windows 7 machine as opposed to the normal vista i used b4... now mirror does nothing & the following gobbldy gook appears in ruby console:

C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/Mirror.rb;266;in `mirror'
C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/Mirror.rb;178;in `onLButtonDown'
C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/Mirror.rb;266

anyone have an idea ?
thanks
