how to access the instance's vertices of a wire by python

how to access the instance's vertices of a wire by python

how to access the instance's vertices of a wire by python

(OP)
I use the abaqus python to create a wire in Interaction Module, sth like this:

mdb.models['Model-1'].rootAssembly.WirePolyLine(mergeWire=OFF, meshable=OFF, points=((mdb.models['Model-1'].rootAssembly.instances['I'].vertices[10], mdb.models['Model-1'].rootAssembly.instances['I'].vertices[11]), ))

mdb.models['Model-1'].rootAssembly.Set(edges= mdb.models['Model-1'].rootAssembly.edges.getSequenceFromMask(('[#1 ]', ), ) , name='Wire-1-Set-1')

then a feature + an edge is created correctly.

And the two vertices for creating this wire are instance's vertices. But when I use the python function Edge.getVertices, it only returns rootAssembly's vertices ID instead of Instance's vertices.

So how to get the instance's vertices.

RE: how to access the instance's vertices of a wire by python

Instances are not created in the Interaction module. Instances are created in the Assembly module from Parts.
You are creating just features in the assembly.
