automate holes on a rounded shaft by relation
automate holes on a rounded shaft by relation
(OP)
Hi all,
I am new to relation in proe, & I had been trying to setup a relation in my shaft model to insert a hole on the shaft's flange.
my relation is as below:
p = floor (d3/2)
ang_slot = 360/p
where
ang_slot is the angle between the 1st hole & datum.
d3 is the o.d. of shaft
Now, the problem is: I tried to insert a pattern feature on model tree to creat a pattern out of it, but when I picked the direction 1 (in dimension setup), & pick the relation selection, I got an error message. What was the proper procedure to do it?
I don't know where it went wrong, & please give me some headsup advices!

Still dont' get it.
How to relate the values inside pattern feature with relation?
RE: automate holes on a rounded shaft by relation
complete the feature
then pattern it... pick the angle dim ..defaults 2
complete it..you don't care at this point
then modify ..pick the angle ...type in your ang_slot
which should be 360/num of divs you want not 360 divided by the od/2
it will ask if you want the relation added..yes you do
your going to want one more tho and it should really before the angle ....360/number divs..let it calc tha angle for you
sorry if i'm writing I have to get to work...but
what you want in the rel table is a num of divs and let that control the rest.. so it will make the angle for full 360
num = how many you want
ang=360/num.... ang increment
so when you change the p value of the pattern..it clas the angle ... note when you insert ang for the angular value... you no longer can modify that as it realtion based... you mod with the "x" holes
RE: automate holes on a rounded shaft by relation
if you want to change that goto the rel table and either delete or insert a commet mark in front so it ignore it
which is /*

Good job in posting responses under limited time constraints. I can't believe that PTC hasn't made it ossible yet to add relations on the fly in wildfire yet which has pissed me off more times than anyone can count. I guess whatever software you use you'll always have to use workarounds.

I really hate that about unions... you could go in a fool around all night long ...but heaven forbid if you're late
