automate holes on a rounded shaft by relation

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!

Regards,

engmechs

RE: automate holes on a rounded shaft by relation

It's sounding like you haven't set up the pattern first to apply the relation too

Hi cadcamguy,

Still dont' get it.
How to relate the values inside pattern feature with relation?

RE: automate holes on a rounded shaft by relation

make your hole....radial...to have the angular ref

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

you will be able to modify the position of the intial hole...but not the pattern once you set the 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   /*

RE: automate holes on a rounded shaft by relation

again sorry for the hasty reply.. but being in union.. I can't be late

Thanks cadcamguy, for your prompt reply.

cadcamguy,

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.
