Guided loft: Create a surface using weights
Description: 5 minutes; Lab exercise: 20 minutes
Change the importance of a profile by increasing
or decreasing the weight value. Changing the weight will change the shape.
Weight values range
between 0 and 3.
Default weight values include:
- One profile - The weight option is disabled.
- Two profiles - The default weight for each profile is 0.
The profiles are
linearly blended.
- More than two profiles - The default weight is 1.
A smooth transition
between two adjacent pairs of profiles is created.
Warning: When more than two profiles
are selected, small values for inner profiles can lead to poor curvature
behavior of the surface around the profile.
The weight should not
be made much smaller than 1.
Use the
Surface Analysis tool to verify an
acceptable result when using a small weight.
