Python make set from reference points 1

[nice_guy]

Hi everyone,
I have some reference point which are defined in my model.
Now I want to produce a set which contains some of those reference point in it and I want to automate this procedure by looping it.
When I look at the recording of the python commands used to do build that set it looks like this:

a = mdb.models['Model-1'].rootAssembly
r1 = a.referencePoints
refPoints1=(r1[5], r1[7], r1[9], r1[10], )
a.Set(referencePoints=refPoints1, name='mySet')

I have some simple logic rules on which point I want in that set, can anyone advice on how can I loop this picking action?

Thanks,
Itay

What you see are the indices of the points (5,7,9,10).

What logic do you want to use?

Example:
You could cycle through all points and check their coordinates. If certain criteria are fulfilled, their index is stored and then used when creating the set.

Thanks!
Problem solved.. so I'll share it here anyway.

refPoints1=[0]*size
j=0
for i in range(start,end,interval):
refPoints1[j]=(mdb.models['Model-1'].rootAssembly.referencePoints)
j+=1
mdb.models['Model-1'].rootAssembly.Set(referencePoints=refPoints1, name='mySet')
