Description

The Curves BlendSurf2 tool creates a surface between two edges with some continuity with their support faces.

Usage

1. Select four sub shapes:
   • The first edge and the related first face
   • The second edge and the related second face
2. There are several ways to invoke the tool:
   • Press the BlendSurface button.
   • Select the Surfaces → BlendSurface option from the menu.
3. A Blend_Surface object is created.
4. Optionally edit the values in the Property editor to choose a different auto scale method and adjust the related properties (see Properties below).

Notes

It seems like this tool currently lacks options to reverse the directions of the blend surface's start and end tangents. However, a workaround exists. By setting the DataAuto Scale property to Manual, a user can gain access to the DataScale1 and DataScale2 values. Multiplying all values in DataScale1 and/or DataScale2 by -1 will reverse the tangency at the start and/or end surfaces. This isn't always enough to fix all issues with some surfaces, but it does correct the tangency direction successfully.

Properties

A Blend_Surface object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Base

• DataSamples (Integer): Number of samples to generate surface.
• DataSources (LinkSubList): Edges and support faces.

Continuity

• DataContinuity1 (Integer): Continuity level with face of edge 1.
• DataContinuity2 (Integer): Continuity level with face of edge 2.

Scale

• DataAuto Scale (Enumeration): Compute scale values to get regular poles, or minimal curvature.
  • RegularPoles (default): ...
  • MinimizeCurvature: ...
  • Manual: Scale values' sign sets tangency direction.
• DataScale1 (FloatList): Scale values along edge 1.
• DataScale2 (FloatList): Scale values along edge 2.
• DataScale Samples (Integer): Number of samples for auto scaling.
