Variable Blend Surfaces

The VariableBlendSrf command creates a blend surface between edges of intersecting surfaces with varying radius values, trims the original surfaces faces, and joins the resulting surfaces.

Steps

  1. Select two intersecting surfaces for variable radius blend on the surfaces near the edge that will be blended.
    Surfaces must intersect.
    Handles will appear on surface edges.
  2. Infinite Plane: Type IP for InfinitePlane options.

  3. Press Enter to use the default radii.
    Or
    Type a new radius distance any time the Radius option displays on the command line.
  4. Specify a command line option.
    Or
    Select a handle to edit.

Tips for using handle grips

The Radius and Distance options appear on the command line when you drag a handle grip.

Radius/Distance options

FromCurve

Select a curve. The radius of the curve at the picked location will be used.

FromTwoPoints

Pick two points to show the radius distance.

 
Handle options

AddHandle

Adds a handle along the edges.

CopyHandle

Adds a new handle using the distance from the selected handle.

RemoveHandle

Visible only when at least one handle has been added.

SetAll

Sets the distance or radius for all handles.

LinkHandles

Editing a single handle updates all handles.

Note

RailType options

DistFromEdge

The distance from the edge curves determines the intersection.

RollingBall

The radius of a rolling ball determines the intersection.

DistBetweenRails

The distance between the edge rails determines the intersection.

TrimAndJoin

Trims and joins the resulting surface to the input surfaces.

History only works if TrimAndJoin=No.

Preview

Displays a dynamic preview. You can change the options and the preview will update.
