Creates sets of glazing, casting, skeleton, panel and hardpoint elements from provided model using geometrical and mechanical procedures.

Parameters:

• collection (Collection) – The collection containing the input entities.

• holeswidth (double) – Maximum allowed hole width.

• youngsmoduli (double) – Remove all parts with small Young’s modulus.

• thickness (double) – Remove all elements with small thickness.

• volume (double) – Remove parts with low volume.

• skeletonholeswidth (double) – Fills holes so that the skeleton set can be calculated.

• tolerance (double) – Tolerance used to generate the skeleton set. Use a large value for cruder output, smaller for more refined.

• hardpointsratio (double) – Ratio above which all parts are kept in the set of elements.

• adjacentfaces (double) – Find the faces that are adjacent to features.

• adjacenthardpoints (double) – The number of expansions performed towards nearby elements. Used to categorize elements around a hardpoint.

• connectpanels (bool) –

  Connection elements that are connected to panel set elements are included in the panel set output.

  0 - Do not connect panel set

  1 - Connect panel set

• detectionfiltertoggle (bool) –

  Disable or enable glazing filtering.

  0 - Do not filter glazings

  1 - Identify glazings above auto-calculated or user defined CofG

• fillholestoggle (bool) –

  Fill holes in selected input.

  0 - Disable fill holes

  1 - Enable fill holes

• glazingflangestoggle (bool) –

  Find the rows of elements around and attached to the adhesive on the glazing.

• hardpointsratiotoggle (bool) –

  Ratio above which all parts are kept in the set of elements.

  0 - Disable hardpoints ratio

• includehardpointscastingstoggle (bool) –

  Controls the location of the hardpoint information.

  0 - Exclude hardpoints from castings set

  1 - Include hardpoints in castings set

• includehardpointspanelstoggle (bool) –

  Controls the location of the hardpoint elements.

  0 - Exclude hardpoints from panel set

  1 - Include hardpoints in panel set

• minimumareatoggle (bool) –

  All patches less than the size specified will be removed from the panel set.

  0 - Disable area filtering

  1 - Enable area filtering

• minimumarea (double) – All patches less than the size specified will be removed from the panel set.

• thicknesstoggle (bool) –

  Remove all elements with small thickness.

  0 - Disable thickness filtering

  1 - Enable thickness filtering

• volumetoggle (bool) –

  Remove parts with low volume.

  0 - Disable volume filtering

  0 - Delete filled holes

  1 - Retain filled holes

Example

Categorize all the displayed elements

import hm
import hm.entities as ent

model = hm.Model()

elems = hm.CollectionByDisplayed(model, ent.Element)

model.categorize_skeleton_model(collection=elems)

Categorize all the displayed components using thickness 0.05 and tolerance 30.0

import hm
import hm.entities as ent

model = hm.Model()

comps = hm.CollectionByDisplayed(model, ent.Component)

model.categorize_skeleton_model(collection=comps, thickness=0.05, tolerance=30.0)

Categorize all the displayed elements and compute the hardpoints for node ID 34 and 43

import hm
import hm.entities as ent

model = hm.Model()

nodes = hm.Collection(model, ent.Node, [34, 43])

elems = hm.CollectionByDisplayed(model, ent.Element)

model.categorize_skeleton_model(collection=elems, hardpointsmask=nodes)
