[Plugin] Mirror

TIG

So the Max 'swapper' script is misinterpreting the transformation of the imported objects ?
If you swap and re-swap back as you were, are you back or has further wrong-transformation happened ?
Seems to me the issue is with the Max swapper script itself, which is clearly flipping the 'mirrored' versions of swapped pyramids about their centers ??
If you used a non-symmetrical object as the two simple/complex we can better see the extent of the 'flipping' which might be a 'rotation' or a real 'scale -1' ??? try a pyramid placeholder with an offset apex so we can clearly see its transformation, and a more complex version for the 'swap'.
The Z-offset issue should be solved if the script correctly flips these mirrored versions...
I know little about Max scripts.
Have you tried looking for solutions over on their forums...

Wow you helped (even knowing little about max script) me to solve the the issue that was a real pain in the @ss for a very long period.
I tended to blame Sketchup but it appears to be a Soulburn replacer problem.
For all who suffered the same issue, Here is a good one (that respects SU components):

Sorry don't understand first proposition ...and second proposition!

it's that the problem that don't work
with 2 or 3 clicks even I split horizontally the rectangle

maybe it works out ok with 2D (but even then, i think you still have to define the Z for proper mirror)

A Copy Rotate works (don't explode the arc) but it's not the mirror function and i must draw some helper lines

[attachment=0:25m1367s]copyrot.jpg[/attachment:25m1367s]

copy/rotate isn't mirroring it though.. using a rectangle for testing doesn't make that immediately recognizable..
(mirroring an object can very literally be thought of as placing an actual mirror on a line and you'll be left with the original component as well as the one you see in the mirror.. there's no 180º rotating happening )

anyway.. the idea for <return> for Z isn't creating new functionality for the tools.. it just makes some situations a tiny bit easier when you're zoomed in close.. if you want to mirror something along the green axis, you select the object, click on one part of the green axis, click another part of the green axis, then inference along the blue axis for your third point.. if you can push <return> for Z, you'd only click the first and second points then <return> tells it your third click is on a vertical axis..

with lathe, you also have to define the rotation axis.. but if this option were in it and you were rotating perpendicular to the ground, you'd only click once then <enter>
(in a round about way, it's the same thing as holding the shift key in order to lock the protractor to the Z axis then using one click to define a point of rotation)

you can see the same behavior in split_to_plane and cut_to_plane.

Yes but the problem was not exactly that the problem was the "explosion" of the arc

So my solution to Group the rectangle before draw anything resolve all headache!
Mirror can be used with any restriction and by Magical mood the arc stay safe!

haha.. i think we're talking about two entirely different things.
TIG knows what i'm talking about because i got the idea from him.. it's not my idea, it's his

would love to see <enter> or <return> give you the Z. would make life that much nicer when picking and hunting around to mirror an object.

TIG

But if you pick two points if gives you a line on the 'plane of mirroring', the third point can be in any direction, provided it's not co-linear with the initial two points: the inference engine makes picking a third point on the plane to make it 'vertical' easy [provided that the initial two points are not already vertically aligned!]... just move the cursor until the rubber-banding turn blue and click the 'plane of mirroring' is now vertical and passing through the initial two points... If you replaced the third mouse click with a <enter> key-press what are the advantages ? you'd probably have to take your hand off the mouse ?? Having the third point replaced by <enter> also screws up the tool as you can mirror in different ways by picking one, two or three points - an <enter> after clicking stops and uses the points so far clicked...

yeah.. i hear what you're saying..
the reason i posted in the first place was because i was doing some mirroring in a weirdish situation (in close with other elements nearby) and was having problems getting the Z inference.. so i was setting 1st & 2nd points then zooming out to get the Z.. in which case, id rather of kept the zoom the same then took my hand off the mouse for the <return> key..

generally though, the mirror plugin catches the Z axis very consistently.. maybe a sweeter idea than <return> would be a double-click (or a right-click?) on the 2nd point forces the Z? is that even possible with ruby?

that said, lathe's axis setting is a little more finicky when it comes to setting the second point and i usually end up drawing a line which defines the rotation axis then snapping to it's end points.. (there's a little box the follows the cursor and you have to click inside of it.. even if it's showing you you're locked to the Z axis, you still have to click in the little box as well)

[EDIT]- oh.. also.. i wasn't suggesting replacing the third click with <enter>... the third click is still necessary in a lot of situations.. i was just thinking IF the <enter> is pressed after the 2nd click then it will go on the Z.. but you're still able to do a 3rd click instead if you need another plane that isn't vertical

bmike

yes, you still need to keep the third click, but if there was an 'option' click or something that simply meant Z on the last point, it would be sweet.

thats the way the mirror works in auto cad, if i remember. you can pick three points, or 2 with a right click or enter to finish the command.

Wow great plugin, Thanks!

function

is there a way to turn off the prompt at the end of the command, so it never erases original geometry?

mitcorb

There probably is. You would have to study the Ruby code and maybe comment out the line(s) that generates it. Conceptually, this would be simple. But I will bet that while you comment out one thing, you might "punch a hole in the bottom of the boat". The author could probably point you to it.

You can edit the code so it does whatever you want...
The closing code that asks the question and makes the erase is easily disabled with a leading #

if UI.messagebox("Erase Original Selection ? ",MB_YESNO,"")==6 ### 6=YES 7=NO
            copy_group.erase! if copy_group.valid?        
      	else ### NO
            copy_group.explode if copy_group.valid?
	        @faces=[]
	        ents.each{|e|@faces << e if e.valid? && e.class==Sketchup;;Face}
			self.gluer(sents)
			@ss.clear
            sents.each{|e|@ss.add(e) if e.valid?}
    	end#if

becomes

#if UI.messagebox("Erase Original Selection ? ",MB_YESNO,"")==6 ### 6=YES 7=NO
            #copy_group.erase! if copy_group.valid?        
      	#else ### NO
            copy_group.explode if copy_group.valid?
	        @faces=[]
	        ents.each{|e|@faces << e if e.valid? && e.class==Sketchup;;Face}
			self.gluer(sents)
			@ss.clear
            sents.each{|e|@ss.add(e) if e.valid?}
    	#end#if

BUT if you want to Mirror and NOT keep the original selected object[s] then how would you do it ?
Clicking on Yes/No [or just pressing the Y or the N key] is hardly a hardship ?

Krisidious

I never use the delete afterwards either. Mirror is normally my symmetry tool. One of the most necessary tools in computer aided architectural drafting in my opinion. The dialog is not a hardship. But I will probably disable it. When I need to remove a previously mirrored object I'll just delete it. I would say that the delete feature is more needed than not. It's quite traditional in the sense of autocad.

TIG

@Kris

You are right - I added that final dialog to make the Mirror tool match most CAD applications, which will prompt you after doing the Mirror to Erase/Keep the original selection.
Feel free to customize it as you will

Agree with this... maybe 1 in 10 do I delete the object.

Thanks for showing where to comment out, I was blowing it up dissecting it!

I can't see the plug any where in my Tool menu.
I had followed the instructions as you set, but I can't find it!

Any suggestion?
Thx

When it has been correctly installed the tool appears in the Plugins menu, a Toolbar [which you might need to (re)activate] if the plugin's image file is also in the Plugins folder AND the right-click context-menu, when there's a suitable selection... As 'Mirror Selection...'

This suggests you might have simply put the ZIP-extracted folder OR the RBZ archive into the Plugins folder, and not 'installed' it correctly ??
Or perhaps you don't have FULL Properties>Security>Edit permissions to the Plugins folder itself and so Windows itself is messing you up, by letting you think you have put the files into the Plugins folder, but actually a VirtualStore has been used...

So... 'how' exactly have you installed this plugin ?

There is [was] a ZIP version around... BUT I recommend that you always use the equivalent latest RBZ archive that is download-able from the SCF PluginStore [linked] - or accessed via the Resources menu above.
Install it using the Preferences > Extensions > Install... button [or even better, when the 'Plugin Store toolset' v1.3~ is launched very shortly, you could use its Installer from the ../Plugins/SketchUcation submenu]
OR why not just use the latest 'Plugin Store toolset' for your Plugins - to AutoInstall, Manage, and much more... all done from within SketchUp itself...
These tools will AutoInstall plugins for you, and can warn about incorrect permissions etc too...
Then there's no need to try and do it manually and make mistakes...

Dear Mr Tig / Frank Wiesner

I have mirror plug in v3.1 revisi 21 Feb 2007 ,i want ask to you sir..
Can i edit the script and change it ^_^ .. but for history and ownership remains in the source

I hope you are willing,cause i really love it for this tool.. ^_^
