Mirror of a mirror?

[Anonymous]

Hi -

I have a model that is a square plate with five features in the top right corner. I want to mirror horizontally and vertically so that the features appear (mirrored) in all four corners. The features are asymmetrical, so I can't just copy them; they need to be mirrored.

I made a selection set of the five features. I can then easily mirror them to the bottom right corner or the top left corner. But what about the bottom left corner? I tried to select the already created top left mirror feature in the mirror tool, but it is not select-able there.

After some trial and error I came up with a solution but a) it is messy and b) it does not seem always to work:

1) Make a selection set of the five features.

2) Mirror to the top left corner. Use the selection set to fill in the "features to be mirrored" box.

3) Make a new selection set of the original five features and also the new mirror feature from the timeline.

4) Mirror to the two bottom corners using this new selection set.

I often do this: mirroring twice to get a component with horizontal and vertical symmetry. Is there a simpler and more reliable way to accomplish this in F360?

I have not explored this further but wonder if this is a general issue when making copies of copies, patterns of patterns, copies of mirrors, etc.

Any suggestions appreciated...

Sounds like hard work, its simpler and reliable for me,

doesn't matter about how many features

Mirror the body one way, then both bodies the other way, and Combine > Join.

Might help....

Can you share your model ? (export as .f3d and attach) ?

Thanks for quick reply. Yes, your solution is good if the part is completely 2-way symmetrical. In this case I am adding 2-way symmetrical features to an existing part that is not completely symmetrical. I could probably rebuild it from scratch using your method and then add on the asymmetrical features. But I would much rather have the flexibility to work either way.

Thanks for reply. I can't send the original part so I made a simplified test piece. With a little more experimentation I found that the trick is to select all the features before starting the mirror tool. To do the 2nd mirror I click on my selection set in the tree (the original features) and then control-click the mirror feature in the timeline. Then I open the mirror tool and everything is there. And so on for a third mirror.

But if I open the mirror tool first and then try to select the existing mirror feature in the timeline - nothing is selected. It ought to work either way, so seems like a bug.
