Model.hm_detectselfsymmetry

Model.hm_detectselfsymmetry(collection)

Finds and returns a point on the plane of symmetry and the normal of the plane.

Parameters:

collection (Collection) – The collection containing the input entities to find the self-symmetry for. Valid entities are elements and surfaces.

Returns:

• hwReturnStatus - Status object

• HmQueryResult - Result object containing the output values:

  • centerString (str)

  • centerCoordinates (numpy.ndarray)

  • normalString (str)

  • normalVectorComponents (numpy.ndarray)

Examples

Find the plane of symmetry of a given geometry

import hm
import hm.entities as ent

model = hm.Model()

_, result = model.hm_detectselfsymmetry(collection=hm.Collection(model, ent.Surface))

print("centerString", result.centerString)
print("centerCoordinates", result.centerCoordinates)
print("normalString", result.normalString)
print("normalVectorComponents", result.normalVectorComponents)

Find the plane of symmetry of a given mesh

import hm
import hm.entities as ent

model = hm.Model()

_, result = model.hm_detectselfsymmetry(collection=hm.Collection(model, ent.Element))

print("centerString", result.centerString)
print("centerCoordinates", result.centerCoordinates)
print("normalString", result.normalString)
print("normalVectorComponents", result.normalVectorComponents)
