i have been using dimension pattern, where in, i have given the increment value for center to center distance as 4.
i need the distance to keep reducing by 0.1 for every instance , like
c-c for my first instance is 4 , 2nd should be 3.9 , 3rd is 3.8 .. and so on ..
how can i achieve this using relation ...
is there any command like "do while", "for" that can be used in creo ...
Thanks in advance.
Solved! Go to Solution.
edit pattern definition and set relations. See following picture taken from CR2.
Thank you for those pics.
I have found out that option to go to relation.
I am not able to successfully create a relation with those variables.
The logic is pretty simple, can do it with a do while command..
but i do not know how to establish a realiton in here (creo)... and am not well aware of the syntax...
can you help me with some examples ...?
Unfortunately, there is no looping construct available in Creo relations. Do while, for, repeat until are all not implemented. All you have is if-else-endif constructs. The evaluation of relations is done in a sort of single pass way. It parses through them in order and does the calculations you need. I have if-else-else-...endif logical constructs that would be graded very poorly in a class with a more powerful language.
yes, i agree.. i went through the the available functions.. here ..
looks like , there is no such function similar to DO WHILE or FOR ...
but if you can find a way to achieve a the result i want with the existing functions , kindly help me out...
(more over, this is a PTC community .. .is there a possibility for the PTC developers to look at these conversations.. looks like no body cares.. )
Thank for that equation.
That seems to work ..
can you please tell the variable "di" means..
but, i used the following equation and it worked ..
memb_i = lead_v - (0.1*idx1)
Thanks a lot..
The variable di is the initial dimension selected to define the pattern increment. In your case lead_v = di = 4 I just specified the dimension in the equation directly instead of using lead_v.
