few doubts on patterens

[leenus2b]

hi

i hav few doubts,



(A)wat r the limitations of patterening i.e..we cant mirror the axial patterened feature like that



(B)wat r the points we should consider do for unpatteren a feature



(C)how to deleate a particular feature which is patterened



(D)how many times we can patteren a patteren



thanking u

I have some of the same questions - I find it very annoying that I can'tmirror an axial pattern, it seems pretty intuitive. That makes me think I'm missing something.


I also hate you can't delete a part of a patterned group, i.e. rounds without deleting the pattern and ungrouping. It seems like a little more (or maybe less) intelligence needs to be put into the pattern feature.

leenus2b:


a) to mirror a axial pattern or any patternyou have to group it first.


C) when you are in the pattern mode click on the black dots that shows up and the part will be excluded.


B) I think there's no such thing as unpattern


d) you can't pattern a pattern.


hope this help

I think you can pattern a pattern, I'm sure I've done it... I'll look in to it again..

 

[arroyopr]

i hope you can find it, that will be very helpfull. I have beentrying to do it for a very long time.

I got this from a presentation give by on eof the PTC guys (Gills Combette - sheetmetal) at the PTC/User Conference last year..


hope it helps. it on WF 2.0.. let me know if yo uare still having problems and I'll see if I can help you out!

but it looks like you still have to group the fisrt pattern before u r able to pattern. I ment pattern without grouping the pattern

 

[AHA-D]

I hear that patterning has been enhanced in WF to what I would call "normal functionality". It's a real PITA in 2001. You have to know if and how you will be patterning before you create the feature, you can't attach any geometry to fixed references if you don't want to run in trouble, ...

I dont see the problem with grouping a pattern? why is this a problem?

 

[arroyopr]

no there's no problem. is just in the first post hewas having problem patterning a pattern and the solutions was to group it first. becuase you can't mirror or pattern without grouping first. i totaly agree with you.my bad ididn't explain it verywell.i just was curious if you can do it in any other way. i already knew how to pattern that way.

Glad we cleared that up!

the reason you are making a group to pattern stuff is that you need to
get it reference to a point generally. By doing this your able to
select features that you where not able to before hand



ie



in your recent post you needed to goup with a point that you had
referenced. by doing this you were then able to pick this as your
reference for patterening. ie where able to using a relational distance
to the curve....



by grouping with a plane which is at a angle.. you get a rotational option... etc...



somethings you can beat easly by just using some of the pattern options
just stock within wf2. but if you doing more advanced stuff u really
need to reference extra geometry.





Problems occurer though when you reference stuff that does not change
with your geometry, so carefull consideration eneds to be taken.





if you need help just post it. there are heaps of aweseome people on here

the inside pattern can just be done via the pattern curve feature. but
the radial style pattern can not. ( least not that i have managed.) it
was done via a



-intersect datum plane and the body .. then using a point and a few
datum planes for construstion. then finally grouping the lot and then
patterening that.

 

[Dell_Boy]

One of the original questions was about mirroring an axial pattern without grouping.



In many cases this can be done by making a dependant copy of the
original pattern and manipulating some of regen actions. This also has
the advantage of allowing you to make the mirror image slightly
different from the original if you so desire.



If you really get stuck you might have to negate one of the pattern dimensions and link it back via relations.
