[Plugin] Mirror

I only rarely happens to me - usually a Curve is kept intact...
If you know you have Curves and experience the problem then you could manually Group the Selection before Mirroring it.
I don't know how to stop the rare 'raw' curve exploding glitch - the method used is basically "the selection is grouped, the group is copied, scaled -1 [to 'mirror' it] and then the original group might be deleted, then the group is exploded so the selection is back as it was but now 'mirrored'.

A Curve shouldn't 'explode' as it's container group explodes but just sometimes it does!
I was aware of the glitch but in a few tests just now I can't get it to reproduce - could you post a small SKP with a failing example ?

tig. is a very strange error.
sometimes it generates and sometimes not.
I have not found a pattern of regular behavior

Tig, I use the Flip Along tool a lot of the time. I also watched a SketchUp tutorial with an official Google instructor saying that he didn't quite get it (flip along). I don't understand what there is that's not to get? How does your Mirror plugin differ or improve what's already available?

With the flip along tool, you can flip along one of the main axes (or those of groups/components) only. This plugin lets you mirror in a bunch of different ways, too.

TIG · 6 Oct 2010, 10:10

As Gai explained... the built in 'Flip' mirrors around the model's axes.
This is also similar to using Scale with '-1', where the 'mirroring' is limited to three directions too.
The Mirror tool allows you to mirror around a point, line or plane depending whether you pick 1, 2 or 3 points.
The most usual is around the plane from 3 points - that way you can Mirror about any plane, not just the axial planes and the mirrored version is related to the plane in the reverse manner to the original selection. To do it with Flip/Scale would involve one or more Rotate steps too.
The other benefit of Mirror is that [like CAD tools] on completion of the mirroring you can choose to keep or delete the original selection - useful when modeling in symmetrical parts etc as the 'copy' part is built-in for you...

Although this is not hard with the native tools either;

Copy the "to-be-mirrored" entity
Do the mirroring (flip or scale)
Paste in place the original entity

But awkward with non-axial flips...

tfdesign · 6 Oct 2010, 11:33

I think it's got to be the sado-masochistic mathematician in me! (incidentally, my old man is a Cambridge-educated topologist! ) I like that "now how can I do this without a plugin?". Sounds good Tig. Thanks for the reply. I'll try and get round to having a go with this tool some time in the not too distant future.

Meanwhile, I have a table to build!

Yes. Do-able, but I can see that it would only be possible if one was good at remembering strings of numbers, repetitions and angles?

Plugins are best then?

you can do it without knowing any angles etc. but it's a pita.. this video makes it look easier than it really is because i didn't include the 5-10 minutes i spent figuring out the right moves (and have spent that same 5-10 minutes multiple times doing this in real drawings).. mirror.rb is a blessing

Change in SU 7. Place axis then scale??

GWD · 7 Oct 2010, 06:13

TIG,

Thanks very much for the outline closer!!!!!! I can use this code in some of mine scripts.

Hello!
Mirror is one of the plugins i use most, but with SU8, the plugin Mirror 3.3 don't work for me. I use SU 8 spanish on Mac OSX Snow Leopard, one message appears in Console window, with SU7 and Mirror 3.1 the plugin worked fine.

I use
windows xp sp3, in Spanish. sketchup sketchup 8 in Spanish and 7 in Spanish
in the two versions generated BugSplats.

the image is made with sketchup 8.
although sketchup 7, BugSplats generates but does not generate error reporting in the console ruby

Hi !

A little off topic but how did you do that animated gif ? It's looking good !

sents=[]
    	ss.each{|e|sents.push(e)}
    	  copy_group=Sketchup.active_model.active_entities.add_group(sents)
      group_miner(copy_group.entities)###v3.1
        new_group=copy_group.copy
      group_miner(new_group.entities)###v3.1
...

The last line is #266.
It seems that there is nothing in the selection to copy... BUT if there is nothing then an earlier part of the code should trap it with an error, starting at line #109


    def activate
        ###Sketchup.send_action("showRubyPanel;")
        self.reset()
        ss=Sketchup.active_model.selection
        if ss.empty?
            Sketchup;;set_status_text("Mirror; NO Selection !")###
    		UI.messagebox("Select Something BEFORE Using the Mirror Tool.")###v2.8
            Sketchup.send_action("selectSelectionTool;")
            return nil
        end
...

Have you messed up the code with the translation ?

I haven't done changes in the code only i have translated the UI.messagebox and the text of the popups windows, i have probe with the mirror 3.3 original version (english) and don't works too.
I don't know if there is a conflict with others plugins.

TIG · 25 Oct 2010, 22:00

Can you try it with the 'Ruby Console' open and post all error messages...
This is a puzzle...

Oxer · 25 Oct 2010, 22:15

I have found the error!
There is a conflict with SketchyPhisics 3.1, remember i work on Mac OSX.
Excuse me, it not was a problem in the plugin there were a conflict.
Thanks TIG¡¡

It's no problem for me! Now it's no problem for you!
¡No hay problema para mí! ¡Ahora no es problema para ti!
