# ScrewModifier(Modifier)

base classes — `bpy_struct`, `Modifier`

class `bpy.types.``ScrewModifier`(Modifier)

  Revolve edges

  `angle`

    Angle of revolution

    Type: | float in [-inf, inf], default 0.0

  `axis`

    Screw axis

    Type: | enum in [‘X’, ‘Y’, ‘Z’], default ‘X’

  `iterations`

    Number of times to apply the screw operation

    Type: | int in [1, 10000], default 0

  `merge_threshold`

    Limit below which to merge vertices

    Type: | float in [0, inf], default 0.0

  `object`

    Object to define the screw axis

    Type: | `Object`

  `render_steps`

    Number of steps in the revolution

    Type: | int in [2, 10000], default 0

  `screw_offset`

    Offset the revolution along its axis

    Type: | float in [-inf, inf], default 0.0

  `steps`

    Number of steps in the revolution

    Type: | int in [2, 10000], default 0

  `use_merge_vertices`

    Merge adjacent vertices (screw offset must be zero)

    Type: | boolean, default False

  `use_normal_calculate`

    Calculate the order of edges (needed for meshes, but not curves)

    Type: | boolean, default False

  `use_normal_flip`

    Flip normals of lathed faces

    Type: | boolean, default False

  `use_object_screw_offset`

    Use the distance between the objects to make a screw

    Type: | boolean, default False

  `use_smooth_shade`

    Output faces with smooth shading rather than flat shaded

    Type: | boolean, default False

  `use_stretch_u`

    Stretch the U coordinates between 0-1 when UV’s are present

    Type: | boolean, default False

  `use_stretch_v`

    Stretch the V coordinates between 0-1 when UV’s are present

    Type: | boolean, default False

  classmethod `bl_rna_get_subclass`(id, default=None)

    Parameters: | id (string) – The RNA type identifier.
    Returns: | The RNA type or default when not found.
    Return type: | `bpy.types.Struct` subclass
