Real-time mirroring in Designer?

[Kurt]

Hi. Is there a way, in AD, to invoke real-time mirroring, such that when I add objects to one side of one or more (grid- or user-defined) lines, it's mirror object(s) is displayed on the other side of the line(s)? There is scattered mention of mirroring in other  comments, but I can't find mention of this feature, if it exists.

Real-time mirroring would be great when creating symmetric images, such as the initial drafting of human faces, custom symmetric symbols, etc.

Thanks.

You can use symbols for this, draw a line, the create a symbol from it, duplicate the symbol Press CMD (⌘) + J on Mac, Ctrl + J On Windows)  and flip it horizontally, move it over and hold shift to keep it level.

Nice tip, thanks. However I see that alter the SCALE of one symbol, the other instances aren't affected. Suppose I want to scale the size of an eyeball on the x and/or y axis? How can I get other instances to scale as well?

...Also, the current symbol system doesn't have mirror functionality where if you move object A towards object B, object  moves towards object A. Positional symmetry isn't maintained.

Not as convenient as in Inkscape but works:

Not sure if there is a better to do this but one way is to group everything in the symbol & then use the Move Tool to scale the group rather than the 'parent' symbol instance:

Try it with this simple Eyeballs.afdesign file to see what I mean.

Thanks all. I'll try these ideas.
