Mirror features to another body

Anonymous — Sun, 20 Mar 2016 13:13:09 GMT

Hi,

I have modeled two bodies with a plane created between the two. One body has a slot feature which I want to mirror to the second body. I select the pattern type as "pattern features" and the midplane as the mirror plane. When I select the slot feature, it show a preview of the slot in the second body, however, when I "apply" the feature it does not appear on the second body.

What am I doing wrong?

When mirroring bodies, you make a mirrored, independent copy of that body. That means that any etiting on body 1 wil not automatically be present on body 2.

This would be possible with components (not bodies) and works for array and circular patterns, but curenly not with the mirror pattern. It is a very often requested feature annd as I understand it it's in the development queue waiting for implementation.

There are a number of workarounds I could suggest, but it is difficult to do as I don't know what your end goal is. sSome more detail is needed.

This is surely a bug with the mirror tool. So Bug Alert!

In the screencast, I try to first mirror the faces of a cylinder then try to mirror an retangular inset. The mirrored inset resulted in a hole through the original part. I'm pretty sure this has worked in the past.

Actually, I recently stumbled across this as well. It is definitely a deficiency in the Fusion pattern commands (mirror is just a pattern with an inverse transform). They do not work across bodies... It came up in this other thread: problem-with-circular-pattern.

We chose to characterize it as "not yet implemented" as opposed to a bug, not that it really matters...

There are some workarounds:

1. In the other thread, it was as simple as rolling back before the Pattern Body and inserting the desired feature. Then, the Pattern Body will pick it up.

2. You can always create the feature as a New Body, pattern the body, then use Combine to do the Join/Cut. A bit clumsy, but workable

In some ways, it is surprising that this hasn't come up more often. If it becomes more common of a problem, we will certainly prioritize a fix.

For a workaround, that works well when the timeline is off:

Extrude/join a narrow cylinder that connects or joins both bodies into one. Do the mirror of the features, then delete the narrow cylinder.

Unfortunately, Create --> Mirror --> Pattern Type: "Feature", if the feature shall be mirrored to another body (even if created together with the first body), still doesn't work in Fusion 360 version 2.0.5688 (released April 23, 2019).

It seems this is (unfortunately) a very low priority feature. It's not in the May 2019 update either, and this thread is from 2016.

It can be worked around in different ways, but I feel we shouldn't have to.

July 2022 and we still need Fusion team fixes this problem.

I come across alot with this! And still no progress!
Fusion Team PLEASE IMPLEMENT THIS FINALLY! All this workarounds are just cumbersome!
This is mandatory i think! Please!!!

Yep I keep having this problem too, and often end up having to do multiple sketches of the same thing on different faces and repeat a feature because the feature won't mirror onto another body.

Issue is still occurring. I was able to work around fairly easily by projecting geometry and then just applying the feature again.

7 years!!!!

7 freaking years and still nothing changed, there are so many of these issues that go back several years that just don't get addressed.

I can't think of any other CSG CAD Program that cannot mirror a feature across a plane to another body.

This bothers me since the beginning and NOTHING changed! Shame on you autodesk!

You obvioulsy don't listen to customers!

still a problem, and a wasted day trying to work out why its not working!

Stumbled across this thread trying to solve the same problem.....one month shy of 8 years.....

Yup, still a thing. I refuse to believe that is such a niche edge case to justify so many years of waiting

I am also waiting for that implementation 🙂
