Flipping object with transformation origin and angle

[ashf]

How do I flip a object if the original object is oblique and has moved transformation origin?
(P.S. the object on attached picture is horizontally symmetric but I would use asymmetric one.)

[PixelPest]

Maybe like so:

1. double

2. flip horizontally+vertically

3. draw a helper line along an edge - extend with shift

4. use Point Transform Tool to align

Thanks. but I suppose this method won't work with asymmetric objects in many case.

Why not? Flipping along 2 axis will mirror. Question is how you determine the mirror axis point - regardless the shape.

In case like attached picture?

What is wrong with the result?

That's what I've done manually so it's not in precisely correct position.

It's easy task with Illustrator's Reflect tool, so I wondered if there's similar way.

That might be a handy tool - but the question remains: What and where is the right mirror axis?

[ashf]

Would be like this.

Ultimately I would like to find out efficient way to flip objects for someone.

This guy is a popular Origami crafter and trying out Affinity.
And he does flipping objects a lot, he's pointing out Affinity is not good at flipping objects.
He has been a Freehand user for more than 20 years and is still using it.

Then I´d go this route:

Thank you.

How do you flip the object in this case?
He flipped and manually rotated the object to flip it along the folding line.

Not the fastest-on-earth-method but mathematically correct:

Thank you for detailed tips!
Very informative.

"Enable Transform Origin" should be being this instead of hacks and workarounds. That's the whole point of a transform origin, except only rotations use it.

Agree, it's inconvenient that the transform origin doesn't work for flipping.
Preferably more options like Illustrator.

So it's been 11 months, has this extremely basic functionality been added yet? (I don't mean hacky solutions)

I've looked and it's not immediately popping out to me and searches are not bringing up anything.

Please have the flip command follow the transform origin.

A simpler workaround. Create a helper rectangle. Nest layer to rectangle. Flip rectangle angle. Unnest shape.

this will flip with the along the center point of the rectangle. You can position this point (along with the rectangle and its rotation angle) freely.

Then do a handstand, clap 4 times and bury a boiled egg in the back garden 🤣

This workaround does not always work either as rotating the rectangle often moves the shape. More importantly workarounds have been known for a long time, but we need a proper solution that works every time and does not involve lots of extra steps for such an extremely basic and easy function.

I fully support the request for a permanent fix. No reason for you to attack me personally. Respect please.

I made a harmless little joke about all of the convoluted workarounds that have been suggested on this thread for years.

Nobody is attacking you, get a grip.

It starts small. Always drifting to the personal level, leaving the objective level. And you still continue in your latest reply to the personal level with „get a grip“. It is 100% up to you to stay on the objective level and not escape to personal level. Get serious. Get grown-up. Stop harassing people. It is you, not me.

1. Use move tool
2. use transform panel and edit the value in „rotation“, add „+180“ behind the current displayed value. Do not delete or overwrite, add after this value.

this will preserve all other transformations of the source object, and any transformed origin.

I know how to do with that. 
But what we need is this. other vector graphic apps do it since decades ago.
