Model.endnotehistorystate

Model.endnotehistorystate(name)

Defines the end of a history state. Must be preceded by a call to Model.startnotehistorystate() with the same name value.

This function is used to group a set of functions into a single undo/redo operation. All functions that appear within the start/end block must be supported for undo/redo.

Parameters:

name (hwString) – The name of the history state. If the name contains spaces, it must be enclosed in curly braces or quotes.

Example

Execute an element remesh operation on two selections of elements , but consider them as a single history operation

import hm
import hm.entities as ent

model = hm.Model()

model.startnotehistorystate(name="Remesh two element selections")

model.setedgedensitylinkwithaspectratio(aspectratio=0)

hm.setoption(element_order=1)

model.setusefeatures(mode=3)

elems1 = hm.Collection(model, ent.Element, list(range(1,101)))
model.defaultremeshelems(
    collection=elems1,
    elem_size=1.0,
    elem_type=2,
    elem_type_2=2,
    comp_mode=1,
    size_control=1,
    skew_control=1,
    edge_mesh_type=1,
    min_size=0.0,
    max_size=0.0,
    max_deviation=0.0,
    max_angle=0.0,
    previous_settings=2,
    vertex_angle=30.0
)

elems2 = hm.Collection(model, ent.Element, list(range(1,201)))
