Model.detach_solids

Model.detach_solids(collection, options)

Separates solids that have shared boundary surfaces by duplicating the common surfaces and breaking, when possible, the connectivity between the edges and vertices of shared surfaces.

Parameters:

• collection (Collection) – The collection containing the solid entities to be separated.

• options (int) –

  Defines the separation method. Valid values are:

  0 - Selected solids are separated from those not selected. Shared boundary between selected solids is preserved.

  1 - Selected solids are separated from each other. Shared boundary between selected solid and those not selected is preserved.

  2 - Each selected solid is separated from all solids it has a shared boundary with.

  3 - Same as options=0.

Examples

Separate solids with IDs 1 and 2 between each other , but keep solid with ID 3 connected to both solid with ID 1 and solid with ID 2

import hm
import hm.entities as ent

model = hm.Model()

model.detach_solids(collection=hm.Collection(model, ent.Solid, [1, 2]), options=1)

Separate solids with IDs 1 and 2 from solid with ID 3 and keep shared boundary between solids with IDs 1 and 2

import hm
import hm.entities as ent

model = hm.Model()

model.detach_solids(collection=hm.Collection(model, ent.Solid, [1, 2]), options=0)
