Loft

class Loft

Bases: CommonBaseModel

Represents a lofted surface, a smooth spatial surface generated by transitioning between multiple spline curves.

In engineering and design, lofts are used to create complex shapes by smoothly connecting a series of cross-sectional profiles. This class enables the representation of lofted surfaces, facilitating their use in computational modeling, simulation, and visualization of aerodynamic shapes, product designs, and more.

splines

A series of splines defining the shapes to interpolate for the loft.

Type:: List[Spline]

num_samples

The number of sample points to generate along each spline.

Type:: int

metadata

Additional metadata for the loft.

Type:: Metadata

Attributes Summary

model_config

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

Methods Summary

`add_spline`(spline)	Add a new spline to the series of cross-sectional profiles, potentially altering the shape of the lofted surface.
`calculate_surface`()	Calculate the lofted surface by interpolating between the splines.
`validate_num_samples`(value)	Validate the 'num_samples' field to ensure it is a positive integer.
`validate_splines`(value)	Validate the 'splines' list to ensure it contains at least two splines with the same degree.

Methods Documentation

add_spline(spline)

Add a new spline to the series of cross-sectional profiles, potentially altering the shape of the lofted surface.

Parameters:: spline (Spline) – The new spline to be added to the series defining the loft.
Return type:: None

calculate_surface()

Calculate the lofted surface by interpolating between the splines.

This method generates a series of intermediate curves by interpolating between the given splines, creating a smooth surface that transitions from one cross-sectional profile to another.

Returns:: A list of lists representing the lofted surface points, where each inner list represents a point on the surface with [x, y, z] coordinates.
Return type:: List[List[float]]

classmethod validate_num_samples(value)

Validate the ‘num_samples’ field to ensure it is a positive integer.

Parameters:: value (int) – The number of samples being validated.
Returns:: The validated number of samples.
Raises:: ValueError – If the number of samples is not a positive integer.
Return type:: int

classmethod validate_splines(value)

Validate the ‘splines’ list to ensure it contains at least two splines with the same degree.

Parameters:: value (List[Spline]) – The list of splines being validated.
Returns:: The validated list of splines.
Raises:: ValueError – If the list contains fewer than two splines or if the splines have different degrees.
Return type:: List[Spline]

Methods:

`validate_splines`(value)	Validate the 'splines' list to ensure it contains at least two splines with the same degree.
`validate_num_samples`(value)	Validate the 'num_samples' field to ensure it is a positive integer.
`add_spline`(spline)	Add a new spline to the series of cross-sectional profiles, potentially altering the shape of the lofted surface.
`calculate_surface`()	Calculate the lofted surface by interpolating between the splines.
