Drafted cylinders (to cones) are not analytic and thus may have small C1 violations to adj face.
User Access:
No change to the way the draft command is used. Where a cylindrical surface is drafted, the command will create a conical surface instead of the interpolated approximation created in earlier versions.
User Impact:
Draft features created in 14.00 will use analytic conical surfaces where analytic cylindrical surfaces are drafted. Draft features created in earlier versions will not change. The conical surfaces created in 14.00 will have the desired continuity described in the diary.
User Access:
Commands Constant Fillet, Elliptical Fillet, Loop Fillet, Chamfer, and Asymmetric Chamfer now have a check box labeled "blend corners" as an optional input.
If enabled, its sub-options "sample density" and/or "density" will become available, when appropriate.
User Impact:
Unlike the existing regular n-blend based corner patch routine that generates multiple tangent-continuous faces to patch a given corner, the "blend corner" option creates a single smooth trimmed face for each corner, via the FEM-based surface fitting method.
This helps produce smoother corners in certain cases.
Just like in the stand-alone FEM n-blend command, the "sample density" option allows the user to chose between automatic sampling of corner boundaries via discretization algorithm which traces along the boundaries within a given tolerance, or according to manually specified value of the sample density.
The density is specified per "side" of the corner in the "density" field.

Make 6-sided n-blend fillet corner smoother
User Access:
For stand alone n-blend command, boundary curves are "refit" whenever such option is specified. Before, only cases with 4 or less sides were refit.
For fillet corners, the refit is used by default.
User Impact:
Now, all n-blend patch cases will use boundary curve "refit" method for smoother n-sided multi-face patches, not just those with 4-sides or less.
This includes both stand-alone n-blend command and fillet corners generated by regular n-blend method.
