Potential bug with rectengular pattern and filet

Hi,

 

Please see attached video showing a potential bug.

Design has a pattern of features were one of the features is filet.

When I change the value of the filet, it changes in the pattern.

When I remove one of the edges, it changes in the pattern.

But when I add another edge, it changes in the first instance but do not replicate to the pattern.

 

I've also added the component file.

 

Plz check.

 

tnx.

This is not a Bug, this is normal behavior.  In your first three instances, the features were already defined in the pattern, you just modified them in some way.  Your last example of adding an edge was not including in the original pattern so it is not added "automatically" to the pattern.  You can edit the pattern and add it, then it will behave just like the other features your mentioned.

 

The Pattern command is not physic, it cannot read your mind, it only works on the features it includes.

I'm sorry but I do not understand this logic.

 

When I'm replicating a feature I expect that ALL the parameters/changes/add-ons/deletes will also be replicated and changed accordingly. What you are saying is that if I've already had an edge selected when doing the pattern I can remove this edge and add it again afterwards but if this edge wasn't selected when doing the pattern I can't add this edge.

But, if I add the edge after the pattern was created it won't be replicated but if I delete the pattern and reapply it then it will be created.

I think this logic is very confusing and might leave 'stealth changes' which are not logged in the time-line and might be impossible to detect.

 

I agree that you can't read my mind, no doubt in that, but if I change a feature which is part of a pattern is it possible to 'reapply' this pattern and make all changes (add/delete/modify) appear in the model? If I can delete the pattern and reapply it, can't fusion 360 do this for me?

 

As I come from Solidworks, this 'normal behavior' in Fusion 360 is quite troublesome and raises some concerns.

As you're copying a feature, not faces I would expect it to work. Even if I remove the fillet from the pattern, click OK, then edit the pattern and reselect the fillet it still fails!

@jeff_strater What do you think? The preview shows correct but when you click OK it changes back.
