BlenderMCP

Feature: Select By Criteria As a retopology agent I need to select mesh elements by flexible criteria So that I can quickly identify and work with specific topology patterns Background: Given Blender is running with MCP addon connected And a mesh object "TestMesh" exists in the scene Scenario: Select vertices by valence range When I call select_by_criteria with criteria "valence" min_value 5 max_value 8 Then the result should indicate success And vertices with 5-8 edges should be selected Scenario: Select faces by vertex count When I call select_by_criteria with criteria "face_sides" min_value 3 max_value 3 Then the result should indicate success And only triangular faces should be selected Scenario: Select ngons (5+ sides) When I call select_by_criteria with criteria "face_sides" min_value 5 Then the result should indicate success And all n-gon faces should be selected Scenario: Select boundary edges When I call select_by_criteria with criteria "boundary" Then the result should indicate success And boundary edges should be selected Scenario: Select by face area When I call select_by_criteria with criteria "area" min_value 0.5 max_value 2.0 Then the result should indicate success And faces within area range should be selected Scenario: Invalid criteria returns error When I call select_by_criteria with criteria "invalid_criteria" Then the result should contain an error message
