Modeler3D.import_nastran(file_path, import_lines=True, lines_thickness=0, import_as_light_weight=False, decimation=0, group_parts=True, enable_planar_merge='True', save_only_stl=False, preview=False, merge_angle=0.001, remove_multiple_connections=False)

Import Nastran file into 3D Modeler by converting the faces to stl and reading it.

The solids are translated directly to AEDT format.

Parameters:

file_pathstr

Path to .nas file.

import_linesbool, optional

Whether to import the lines or only triangles. Default is True.

lines_thicknessfloat, optional

Whether to thicken lines after creation and it’s default value. Every line will be parametrized with a design variable called xsection_linename.

import_as_light_weightbool, optional

Import the stl generatated as light weight. It works only on SBR+ and HFSS Regions. Default is False.

decimationfloat, optional

Fraction of the original mesh to remove before creating the stl file. If set to 0.9, this function tries to reduce the data set to 10% of its original size and removes 90% of the input triangles.

group_partsbool, optional

Whether to group imported parts by object ID. The default is True.

enable_planar_mergestr, optional

Whether to enable or not planar merge. It can be "True", "False" or "Auto". "Auto" will disable the planar merge if stl contains more than 50000 triangles.

save_only_stlbool, optional

Whether to import the model in HFSS or only generate the stl file.

previewbool, optional

Whether to preview the model in pyvista or skip it.

merge_anglefloat, optional

Angle in radians for which faces will be considered planar. Default is 1e-3.

remove_multiple_connectionsbool, optional

Whether to remove multiple connections in the mesh. Default is False.

Returns:

List of ansys.aedt.core.modeler.cad.object_3d.Object3d, dict

New object created and nastran dictionary.
