[Plugin] Mirror

TIG

The usual usage for this tool is "3-point", which then defines a 'plane', about which a 'mirror' [reflection] occurs.

A "2-point" transformation, 'about a line', cannot do what you seem to consider to be a true 'mirror' [reflection] - although technically I suspect that it is - because the object is rotated around the line, but keeps its original orientation otherwise.
e.g. If you were to try to do this manually, then you could not expect an arbitrary 2-points to set in train what you wish, because a third point is needed to determine the 'plane' about which the hoped-for mirroring can be done...

Great extension that I use all the time. I realize this is free so just want to drop a few suggestions to consider if you spend any more time developing this extension:

A cancel option would be great at the Delete original object prompt, i.e. Yes / No / Cancel. I realize a ctrl-z will undo the mirror, so if it's too much effort/time to add the feature, then I will continue using ctrl-z.
Any way to use the native / (divide) command after the mirror? I often draw a screw or bolt at a location, then mirror it about a plane, then want to add evenly spaced ones in between. currently I just copy the original item onto the mirrored item, then use the / command, then delete the copied one but if possibly immediately after using mirror that would be a time saver.

Again, thanks for such a great extension.

Hi

I am Ho Young and I am a 3D background designer in Korea. I work with sketchups and sell my 3D modeling to cartoonists.

I joined this site for free. I want to use 'TIG' plugins in my working in sketchup.

I want to use TIG plugins which name is MIRROR, FRACTURE, WELD, etc. Can I also use TIG plugins not mentioned?

I downloaded the plugin for free from this site. Do I have to pay you a plugin fee?

I never sell your plugins. just I want to use your plugins to create 3D modeling and sell my 3D modeling to cartoon's background. Can I use it?

Thank you for making such a great plugin. Thank you very very much. You are really genius.

I am not good at English and thank you for reading.

To clarify things.

Most Plugins and Extensions at SketchUcation are free to download and use.
If you find they are useful, then you can always make a voluntary donation via PayPal, using the button associated with the tool's entry.
The choice to pay something is yours.
If you use these Plugins commercially [as you seem to be] then you might feel some compunction to give back something in return, but it is not compulsory.
So if some Plugins save you considerable time and effort, then making a donation of a very small proportion of what you earn would seem fair?

Rather than distribute copies of these yourself, I recommend that you point others to the SketchUcation PluginStore, so that they can get them direct.
You should never sell things which can be got for free.

A few Extensions are available to buy through the Shop.
Obviously you pay for these and should not distribute them to others.

Anyone else has experienced crashes using the mirror plugin in V2020?

Mirroring nested groups and/or components several times have caused a crash of SU (bugsplat screen). Sometimes it goes ok, sometimes not.

Saving the file now before using the command. Pre 20 never had to do that.

TIG

I've tested it quite a bit in v2020, and do not see any BugSplats...

Anything specific in your case ?
e.g. scaled instances, Outliner open etc ??

Strange, nothing specific (to me) although;

outliner is always open - was never a problem pre v20
the top part in the hierarchy is a component with axis at the origin
nested in this main component are many groups.

Will keep an eye open next week for crashes and see if I notice a pattern.

Same crash for me with Sketchup 2020...
Sometimes crash, sometimes not. Strange.
Thank you for your work.

HI, the circle issue again, but currently in V2021 your argument that circle can't be copied without a face is untrue. The circel stays now intact!

Can you correct this behaviour for mirror also?
For CNC work this would be great.... as you probably know.

Thanks in advance,

Searchie

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...

Help! I love this plugin (easily the best and my most used of all plugins).

However, my '21 SU (Mac) has been crashing when closing or switching files which, as I understand, is typically a plugin problem. I removed the plugin and it seemed to fix this issue. I tried downloading and re-installing the plugin with the latest version, but that does not seem to resolve the crashes.

Please help! I miss it so dearly.

Mirror doesn't do anything to SketchUp's internal settings.
It works fine for me in v2021 [PC].
What's your MAC OS ?

So its use should not be connected...
Can you run it with the Ruby Console open and report any error messages...

Hello,
I have an idea - it would be very handy to have an axis snapping feature based on keyboard arrows, similar to the one in the native line tool.
The exact behaviour I have in mind is:

Activate the tool,
Pick first point,
hit one of the keyboard arrows while guiding a "virtual line" to lock direction: X, Y or Z,
possibly repeat for the second line, so the two lines will quickly form one of the main planes: XY, XZ or YZ. Alternatively, only one line could be locked to a main axis, and the other would be drawn freely.

Sure, there is axis snapping for this tool already, and it works well. Though, in some situations using arrows to instantly snap the "virtual line" to axes would benefit for working speed.

It's just a suggestion, if you have time and will to further develop this tool

The Mirror extension doesn’t seem to be locking to any axis when arrow keys are pressed.
Sometimes its very difficult to lock to a particular axis with cursor(mouse) only.

Using arrow keys to lock to a particular axis would be a very helpful feature to this extension.
Just like native drafting tools in sketchup.

Try adjusting your viewpoint in the model, then it works as well as the native line command.
