Fillet feature dialog box

Adds fillets or rounds to one or more edges of a part, between two face sets, or between three adjacent face sets.

Access

Ribbon: 3D Model tab Modify panel Fillet

Edge fillets: Adds fillets or rounds to one or more edges of a part. You can create constant-radius and variable-radius fillets, fillets of different sizes, and fillets of different continuity (Tangent or Smooth G2) in a single operation. All fillets and rounds that you create in a single operation become a single feature.

Constant tab

Sets the parameters for adding constant-radius fillets. If necessary, click More to set the options for fillets and rounds.

Edges

Defines a set of edges to fillet. To add edges, select the set from the Edges box, then click the edges in the graphics window. (To remove edges, press Ctrl as you click.) To add another edge set, click the prompt in the last row of the Edges box. Use Select Mode to simplify the selection of edges.

Tip: To select a single edge without selecting edges that are tangent to it, click More, and then clear the Automatic Edge Chain option.

Radius

Specifies the fillet radius for the selected set of edges. To change the radius, click the radius value, then enter the new radius.

Applies Tangent (G1) fillets which are tangent to adjacent faces. Click the arrow to select the continuity from the list.

Applies Smooth (G2) fillets which are curvature continuous to adjacent faces. Applying this option causes changes in curvature to occur gradually, resulting in smoother, more aesthetically pleasing transitions between faces. Click the arrow to select the continuity from the list.

Select Mode

Changes the selection method for adding or removing edges from an edge set. Click to select the mode from the list.

Edge selects or removes single edges.
Loop selects or removes the edges of a closed loop on a face.
Feature selects or removes all edges of a feature that do not result from intersections between the feature and other faces. If used in the assembly environment, only part features can be selected.
Solids selects the participating solids in a multi-body part. Not available in a single body part.
All Fillets selects or removes all remaining concave edges and corners. This mode requires a separate edge set. Not available in the assembly environment.
All Rounds selects or removes all remaining convex edges and corners. This mode requires a separate edge set. Not available in the assembly environment.

Variable tab

Sets the parameters for adding variable-radius fillets. If necessary, click More to set the options for fillets and rounds.

Edges

Specifies edges to fillet. To add an edge, select the prompt in the Edges box, then click the edge in the graphics window.

Tip: To select a single edge segment without selecting edges that are tangent to it, click More, and then clear the Automatic Edge Chain option.

Point

Selects the start point, endpoint, or an intermediate point so that you can enter its radius.

Radius

Sets the fillet radius at the selected point. To change the radius, select the point in the point list, then enter the new radius.

Position

Specifies the position of the selected point. To change the position, select the point in the point list, then enter a value from 0 through 1 as a percentage of the length of the edge.

Note: If the selected edge contains multiple tangent edge segments, the position is relative to the start point of individual edge segment on which the point resides.

Smooth Radius Transition

Defines how variable-radius fillets are created between control points. Smooth is the default setting.

Select the check box to create fillets with a gradual blending transition between the points. The transition is tangent (no rate of change between points).

Clear the check box to create fillets with linear transitions between the points.

Setbacks

: Defines tangent continuous transitions between fillets on intersecting edges. You can specify a different setback for each edge in an intersection.
Vertex: Specifies the vertex of the intersecting edges. Select the vertex in the graphics window.
Minimal: Allows the system to define the minimum allowable setback for a given vertex. Often provides the smoothest transition, and increases the success rate of solving difficult vertex fillets.
Edge: Specifies one edge of the edges that intersect at the selected vertex. Select an edge in the graphics window.
Setback: Specifies the setback distance. Enter the distance.

Face fillets: Adds fillets or rounds between two selected face sets, which need not share an edge.

Face

Sets the parameters for adding fillets between faces. If necessary, click More to set a help point if the preview fillet is not as expected.

Face Set 1

Specifies one or more tangent, contiguous faces from the model or surface body to include in the first set of faces to fillet. To add a face, click Select, and then, in the graphics window, click the faces.

Tip: To select more than one face per face set, clear the check box for Optimize for Single Selection.

Flip reverses the side on which to create the fillet when selecting surfaces.

Face Set 2

Specifies one or more tangent, contiguous faces from the model or surface body in the second set of faces fillet. To add a face, click the Select command, and then click the faces in the graphics window.

Note: The selected face set is highlighted in the color indicated on the Select command to distinguish between selection sets.

Flip reverses the side on which to create the fillet when selecting surfaces.

Include Tangent Faces

Sets the face selection preference for face fillets. Select to allow the fillet to continue over tangent, adjacent faces automatically. To create the fillet between only selected faces, clear the check box. This option does not add faces to or remove faces from the selection set.

Optimize for Single Selection

Automatically advances to the next Select command once a single selection is made. Clear the check box when making multiple selections per face set. For multiple selections, in the dialog box, click the next Select command, or on the context menu, select Continue to finish a particular selection.

Radius

Specifies the fillet radius for the selected set of faces. To change the radius, click the radius value, then enter the new radius.

Note: Does not preview without a valid radius value.

Full Round Fillet: Adds variable-radius fillets or rounds that are tangent to three adjacent faces. The variable-radius fillet replaces the center face set. To cap or round exterior part features, such as ribs, use Full Round Fillet.

Full round

Sets the parameters for adding a variable-radius fillet between three adjacent faces. To specify whether to preserve all features that intersect with the fillet, click More.

Side Face Set 1: Specifies one or more tangent, contiguous faces from the model or surface body that are next to the center face set. To add a face, click Select, and then, in the graphics window, click the faces.

Tip: To select more than one face per face set, clear the check box for Optimize for Single Selection.
Center Face Set: Specifies one or more tangent, contiguous faces from the model or surface body that are replaced with the fillet. To add a face, click Select, and then, in the graphics window, click the faces.

Note: To distinguish between selection sets, the selected face set highlights in the color indicated on the Select command.
Side Face Set 2: Specifies one or more tangent, contiguous faces from the model or surface body that are next to the center face set. To add a face, click the Select command, and then, in the graphics window, click the faces.
Include Tangent Faces: Sets the face selection preference for face fillets. Select to allow the fillet to continue over tangent, adjacent faces automatically. To create the fillet between only selected faces, clear the check box. This option does not add faces to or remove faces from the selection set.
Optimize for Single Selection: Automatically advances to the next Select command once a single selection is made. Clear the check box when making multiple selections. For multiple selections, click the next Select command in the dialog box or select the Continue command in the context menu to finish a particular selection.

(More)

Sets the options for fillets and rounds. The default settings are correct for most fillet features.

Roll Along Sharp Edges

Sets the solution method for edge type fillets when the specified radius would cause adjacent faces to extend.

When selected, varies the specified radius when necessary to preserve the edges of adjacent faces.

When not selected, maintains a constant radius and extend adjacent faces when necessary.

Rolling Ball Where Possible

Sets the corner style for edge type fillets.

When selected, creates an edge fillet defined as if a ball had been rolled along the edge and around the corners.

When not selected, creates a continuous tangent transition between edge fillets in sharp corners.

Automatic Edge Chain

Sets the edge selection preference for edge fillets. Select to select all tangent edges automatically when selecting an edge to fillet. To select only the indicated edges, clear the check box.

Tip: To select part of an edge that already has filleted corners, clear the check box.

Preserve All Features

When selected, checks all features that intersect with the fillet. Their intersections calculate during the fillet operation. When not selected, only the edges that are part of the fillet operation calculate during the operation. (All fillet types.)

Help Point

In rare conditions, face fillets have multiple solutions. Specifying a help point can help resolve ambiguity, allowing face fillet to provide the appropriate solution. Select to enable help point selection, and then specify a location on a selected face which is nearest to the appropriate fillet. The proximity of the selected point forces the creation of the resulting fillet at the intended location.

Preview: Provides a preview of the fillet based on the current selections.
