Lofting has its heritage from shipbuilders as they laid out ship hulls. They passed imaginary lines between multiple sequential cross-sections. A lofted surface creates a smooth surface from cross-sectional curve data. The curves can be non-planar as well.
To create a Lofted Surface:
- Select Construct tab > Surfaces panel > From Curves > Loft to display the Lofting dialog.
- Optionally enter a name in the Surface name field.
- Select a curve from the
Curve list, or click the
Pick Curve
button and select it in the graphics window.
- Repeat step 3 to select more curves. You need to select at least two curves to create a lofted surface.
- Use the
Move item up
,
Move item down
,
Reverse selected curve
, and
Delete item
buttons to set the sequence and direction of the curves in the lofted surface.
- Select Interpolated or Spline. Click Preview to see the difference.
- Optionally select Uneven spacing. Click Preview to see the difference.
- Optionally select Reparameterize curves.
- Click Preview to display a preview of the surface in the graphics window.
- Click OK.
