Script to generate edge set from different CAD models 1

[skr3178]

Hi,
I used abaqus macro recording when defining set: by edge(20 deg). My end goal is run through the script different models/geometries which are identical in every aspect except for a few parametric values. For both models, I am using the same procedure for selecting the highlighted edges:create set from edge-by byedgeangle-20.
However, when I run it through for other geometric models, it selects an entirely different "e.getSequenceFromMask" or as I should say entirely different sets for "e.findAt" after running the commands for the similar edge

session.journalOptions.replayGeometry
session.journalOptions.setValues(replayGeometry=INDEX)
I am aware that the program has restrictions over findAt :

findAt initially uses the ACIS tolerance of 1E-6. As a result, findAt returns any edge that is at the arbitrary point specified or at a distance of less than 1E-6 from the arbitrary point.

I would appreciate if anyone can suggest how to ensure same edges are for different geometries when using the e.find at command.

When the position of the edges varies slightly, so the tolerance of 1e-6 is too tight, then you could try using getClosest().

Hi,
I am fairly new with scripting and this might be a novice error which I have been trying to work on for several hours.
I would like to select a vertice/node from a point closest to (0.0,5.0,0.0). Running the getclosest(coordinate=....) is preventing me from creating a set.
When I record through macro, the following command is executed

a = mdb.models['model-11'].rootAssembly
    session.viewports['Viewport: 1'].setValues(displayedObject=a)
    a = mdb.models['model-11'].rootAssembly
    v1 = a.instances['Circular_knit - 2, 3, 11-1'].vertices
    verts1 = v1.getSequenceFromMask(mask=('[#0 #10 ]', ), )
    region = a.Set(vertices=verts1, name='Set-2')
    mdb.models['model-11'].EncastreBC(name='BC-1', createStepName='Initial', 
        region=region, localCsys=None)

where
verts1 = mdb.models['model-11'].rootAssembly.instances['Circular_knit - 2, 3, 11-1'].vertices.findAt(((0.0, 5.0, 0.0),),)

Instead I am running code

a = mdb.models['model-11'].rootAssembly
v = a.instances['Circular_knit - 2, 3, 11-1'].vertices
r=v.getClosest(coordinates=((0.0,05.0,0.0),))
region = a.Set(vertices=verts1, name='Set-2')
TypeError: keyword error on vertices

I think the problem is with the type of variable being created. How to convert between data types?Any help would be appreciated.

type(r)
<type 'dict'>
type(verts1)
<type 'Sequence'>

I think I found the catch.
Instead of using getclosest(coordinate=....), I switched to using verts1 = v1.findAt(((0.0, 5.0, 0.0), ))
and it worked.
