Loft a surface body
Learn how to use the Loft command to create a surface body in Fusion.
On the toolbar, click Surface > Create > Loft .
The Loft dialog displays.
In the canvas, select two or more Profiles to loft.
In the dialog, select an end condition or continuity for the first and last profiles:
- Connected
- Direction
- Connected (G0)
- Tangent (G1)
- Curvature (G2)
If the first or last profile shares a connected face, and continuity is set to Tangent (G1) or Curvature (G2), adjust its edge alignment:
- Free Edges
- Align Edges
- Align To Surface
Select a Guide Type:
In the canvas, select the rails or centerline.
Select an option for Tangent Edges:
- Merge: Merges edges of tangent faces into a single face.
- Keep: Maintains edges between adjacent tangent faces.
Select an Operation, and adjust its associated settings:
- New Body: Creates a new body in the active component.
- New Component: Creates a new body in a new component.
Optional: On the Analysis tab, select an Analysis Type to analyze the previewed result in context:
- None: Displays no analysis.
- Zebra: Displays alternating black and white stripes on a body to help you analyze surface curvature.
- Curvature Map: Displays a color gradient on a body to help you analyze areas of high and low surface curvature.
- Isocurve Analysis: Applies UV mapping and curvature combs to help you analyze the quality of the surface curvature.
Click OK.
The lofted surface body displays in the canvas.
Tips
- Use Tangent Chain to dynamically control selection sets.
- To create a closed loop Loft, check Closed to connect the first and last profiles to each other.
- Add rails to gain additional control over the shape of the lofted body.
- Select labels in the canvas to change settings for individual profiles, rails, or centerlines.
