Loft

Use Loft to create a 3D solid that smoothly transitions between two or more sketch profiles. Loft is essential for blended mechanical forms, tapered transitions, aerodynamic surfaces, and geometry that changes cross-sectional shape along its length.

Options

Sketches

Select two or more sketch profiles in order from start to end. The sketches can have different shapes and sizes - position them where you want them along the loft.

Surface Degree (V-Direction)

Controls how smooth the transition is between profiles. Default is 3 (cubic), which gives smooth curvature. Higher values create smoother transitions but compute slower:

• 1 - Linear (straight blend)
• 3 - Cubic (smooth, recommended)
• 5+ - Very smooth transitions

Bezier Approximation

Enable this to use Bezier math instead of rational B-splines. Can help with compatibility in some downstream tools.

Base Curve Index

Specifies which sketch (counting from 0) to use as the base for interpolation calculations. Affects the blending between profiles.

Start Tag and End Tag

Tag the first profile's face or the last profile's face to reference them later.

Body Type

Choose solid (requires closed profiles) or surface for a shell without thickness.
