Chamfer Surfaces

 History enabled

The ChamferSrf command creates a ruled surface as a bevel between two input surface edges.

Steps

  1. Select the first surface.

    Click the surface at the side you want to keep after chamfering.

  2. Select the second surface.

    Click the surface at the side you want to keep after chamfering.

Warning

This command works on the analogy of rolling a ball of a defined radius along the edges of the surfaces. If a corner is narrower than the ball radius, the ball cannot negotiate the turn, which can cause the command to fail.

Command-line options

Distances

The distance from the intersection of the surfaces to the edge of the chamfer.

Extend

When one input surface is longer than the other, the chamfer surface is extended on the longer edge.

Trim
Yes

Trims the original surfaces to the intersections with the resulting surface.

No

Does not trim.

Uses the output surface to trim the input surfaces when possible.

History is supported when the Trim=No.

Split

Splits the original surfaces at the resulting surface edges.

Fillet Surfaces

 History enabled

The FilletSrf command creates a constant-radius round surface between two surfaces.

Steps

  1. Select the first surface.

    Click the surface at the side you want to keep after filleting.

  2. Select second surface.

    Click the surface at the side you want to keep after filleting.

Warning

This command works on the analogy of rolling a ball of a defined radius along the edges of the surfaces. If a corner is narrower than the ball radius, the ball cannot negotiate the turn, which can cause the command to fail.

Tips

  • Always fillet from the largest radius to the smallest radius across a model.
  • Remove any edges you can prior to filleting with MergeAllCoplanarFaces or by way of surfacing in a simpler manner. Fewer intersected edges = Fewer problems as the fillet rolls along any edges and tries to trim and join with the adjacent surfaces.
  • Make sure there is enough room for the fillet surface to trim and join with adjacent surfaces. The angle relationships between surfaces, sharpness of the bend in the rail around corners and rail type all play a part in any particular case.

Command-line options

Radius

Sets the radius of the fillet surface. It will be the initial value of the Radius slider in the options dialog

Options

Radius

Move the slider to change the radius, or double-click on the slider to enter a value.

Range

Click a number button to change the range of the slider for smaller or larger adjustment.

Blend Type
Arc

Creates a fillet surface with arc sections and tangent (G1) to the input surfaces.

Deformable

Adds more control points to the fillet sections for adjusting tangency and bulge.

Deformable degree

Sets the degree of fillet sections from 3 to 5.

Tangent

Moves the second points on both ends in the tangent direction.

Bulge (For degree 4 and 5)

Moves the point(s) in the middle to make the fillet sections sharper or flatter.

G2 Blend

Creates a blend surface connecting to the input surfaces with curvature (G2) continuity.

Trim

Uses the output surface to trim the input surfaces when possible.

History is supported when the Trim checkbox is disabled.

Extend

When one input surface is longer than the other, the fillet surface is extended on the longer edge.
