pattern failure paradigm

[dgschaefer]

I believe that if you select fix model (not quick fix) and then select
feature / pattern / delete pattern / failed feature you can do exactly
what you want. I may have the menu wording wrong or in the wrong order,
but you should be able to figure it out.

I really wish there is an answer to this....if I understand it
correctly. I've many time struggled and faced the fact that the pattern
must be deleted, then fix any issues - then re pattern. Truly stings
when using reference patterns.

[jbennett]

That sounds like a correct way to do that. But if that doesn't work, try the investigate tool inside of the resolve mode. It takes out alot of the guessing games on what is wrong. I know that resolve mode can be intimidating, but try it out.

thanks

Thanx Doug! Deep within the 'Fix Model' menu I was able to find the
'Delete Pattern' button. Not really sure why this would be buried so
deep, but I'm glad you pointed it out. And to think all these years
I've been deleting and recreating the feature... hmmm

What gets me is when you mirror a pattern. If you want to change the pattern the mirror won't update and you have to delete then recreate the mirror. You'd hope a regeneration would fix it but it doesn't. 😉

[dgschaefer]

This is one reason of several why I never mirror features. If a part is
largely symmetric, I build it in half and then mirror the entire part
(select the top node of the tree, click the mirror icon) then I'll build
the asymmetric features. Or I'll simply build each feature as symmetric
in the sketch.



Copying or mirroring features locks up the original and limits how you
can change it later in ways I'm not willing to live with.

One way around is to MIRROR copied surfaces and then solidify. If things fail, it's generally fixable by simply redefining the copy surface.. Just another option....

I have done this before but somehow forgot how to do it.

In a part, I want the mass in the model tree listed in a column so it continually updates as the part is modified.

Hi Folks,
And to follow up from Paul's comments the same copy surfaces method that he
suggests for mirror works well for pattern too. You then solidify the
surfaces using reference pattern. Very robust.

In fact it has been a recommended technique for doing complex patterns such
as a fan blade for a very long time. I have an old Tips and Techniques
book that is from R14 that shows this.
