Pattern every 2nd instance offset down

[puppet]

Greetings from the past.
I am looking to create a pattern where every other instance is offset down based on a variable.
Like the below.

×××.......×××.......×××.......×××
.......×××......×××........×××

There are a couple of ways you can do this:

1) By creating a pattern which would include all positions and then click the black dots to remove every other instance you don't want.
2) Create a pattern for the first line and then pattern the pattern in x & y to give the second line (although this will give 4 instances of xxx in row 2 - not sure if this is what you want?).

Hope that helps?

Pattern it in 2 directions and turn off every other instance via the black dots...

Take a look at this, it uses a relation for the second direction:

(much easier than clicking on dots)

Hey dross thats how i solved it.
equations are much better than clicking the dots.
mem_v and idx1

Using idx1 to test for every alternating instance and mem_v to set my value
thx

From the tutorial:
"Create the Pattern To create a staggered pattern, use only one direction, and use two dimensions. Write relations for one of these dimensions to cause the staggered effect."

This doesn't seem to work in Creo 3.0. I see the tutorial was written for Pre-Wildfire Pro/E. Is there something different that needs to be done to make it work in Creo?

Sorry, don't know how to make it work in Creo.

hmmm, i dont have time to try but you could try writing the relation


off = -1^IDX1
memb_v = if(off <1, (lead_v)*(2), lead_v)

I was playing around with something siimilar in creo 3 and it worked...
