Point Transform Tool - duplicate + mirror

Recommended Posts

I'm trying to duplicate and mirror an object. I found the point transform tool, which only seems to rotate and duplicate, but not mirror. In this illustration, the 'mirror' gets to the other side, but upside down and below where I want it.

Any help is appreciated.

Having got it to that position, is there any reason why you can’t simply flip it vertically and then align it (again, vertically) to the top of the original ‘mirror’? :/

Yup, in the meantime I did something like that, but WOW it was more work than I anticipated - initially thought I was using the wrong tool.

I'm coming from Illustrator where it is a simple process with the rotate command, pick the origin point + CTRL (to duplicate) + SHIFT, (to constrain to angles) done.

Hopefully Designer gets there soon.

I wonder why it is not even easier + possible, to flip horizontally with the rotation point as flipping distance (axis)?

Situation before flip:

I would expect a horizontal flip would mirror the trapezopid to the left side of the rectangle. – But instead I get this:

The rotation point is flipping with the object around the object center. – Why?

@PixelPest yeah I was aware of that procedure however I don't see it being practical in the situation I posted above.

Are you sure?

Nope, all I get is move (four arrows) when using only the point transform tool. Maybe this is a Windows only defect?

While you need to constraint the anchor point horizontally to the guide snapping with shift key - still hold shift key down - then transform.

I really appreciate your input, but I'm just not getting transform handles no matter what combination of key presses I make. I can rotate and move, but not transform like you did.

No biggie as I went through the process @Alfred suggested. Took a bit longer and IMO was kinda clunky, but it worked.

Yes - drag the transform thingy to the mirror axis - cmd+J - flip horizontally - move over till transform point meet mirror plane - no big deal.

I wonder why not at least the 9-point-set at the transform panel have any effect either.

I can get this to work fine on curves that I have drawn, I am trying to do something using the vector brush, whatever I try and however I flip or reverse the curve it will not work. The curve path mirrors but the brush doesn't. I have attached the result below, I want a mirror of the curve on the left...I end up with upside down bees :4_joy: ...the only way I can get around this is to create a new brush with the bee facing the other way :) Do you know a way to make this work as I need to do this sort of thing quite often.

There is a flipping workaround that I saw the voodoo priest of workarounds @JimmyJack use... see the voodoo below.

Flipping-trick.gif

basically you make the duplicate a child of whatever you wish to flip around and then remove it.

If the flipping object is asymmetrical once you have removed the flipped piggybacker you can flip the flipper back. :D I'm sure there's a tongue twister there somewhere. 

Ps. I'm patenting the wing mirror design and will be used ostensibly for knocking bikers and pedestrians flying, creating drag to make you use more fuel (I have shares in the oil companies) and allow pretty ladies to stand by my car and apply make-up. :D

Note that since the advent of the Point Transform Tool, the point is now called the "Transform Origin," not the rotation point.

Anyway, I think the reason for this is the origin could be set to any location, including one very far off the canvas like in this flip the cat.afdesign example. Image what would happen if it worked like you expected -- flipping the cat horizontally would place it twice as far off the canvas as its original location.

That probably isn't what one would want normally, but more to the point I'm not sure how it would work when using the method @PixelPest mentioned to snap the object across the mirror axis.

Ignore the flipping - and let go when size is right - then hit "Flip Vertical" - done.

Its not really working, they end up facing the same way...I need them facing the opposite way and the right way up :) A true mirror Image doesn't seem possible when using the Vector Brush :(

Maybe I'm missing something, but why not just duplicate the brush layer, use the Point Transform Tool as in this post by @PixelPest (& as shown in my movie) to move (not rotate) that layer to the mirrored position? Then just use Flip Horizontal to make them face the other way.

I have done all of that, they always end up facing the wrong way or upside down, have you tried it with a vector image brush that has an obvious top and direction ?

I used the chain image brush so I didn´t notice.

Thanks, at least I am not going mad :)

Thank you. Hm, this more general name makes me even expect more to become respected and used when flipping an object. Whereas the cat sample does not confuse me at all, since the point must have been moved by the user to this position in purpose, so I assume the (same) user would be aware of it (– btw: is there a way to click-reset that point to the object center?)

Additionally I am confused why a 3x3 square selection in transform panel is neither respected/used for rotation nor for flipping but simply ignored.
