About Creating Fillets

What is a Fillet Feature?

A fillet is a curved face of a constant or variable radius that is tangent to, and that joins, two surfaces. Together, these three surfaces form either an inside corner or an outside corner.

The curved surface of an outside corner is generally called a 'round' and that of an inside corner is normally referred to as a 'fillet'.

Edge fillets are smooth transitional surfaces between two adjacent faces.

Reshaping Corners

The Blend Corners option available from Edge Fillet and Variable Radius Fillet dialog boxes lets you quickly reshape these corners. For more information, see Reshaping Corners.

Interrupting Fillet Computations

If the fillet definition needs modification, you can interrupt the feature computation launched after clicking OK. This is possible when the computation requires a few seconds to perform.

If the computation exceeds a certain amount of time, a progress dialog box appears providing. To interrupt the operation, click Cancel. This interrupts the process and displays an Update Diagnosis dialog box enabling you to edit, deactivate, isolate or even delete the feature.

This capability is available for any type of fillet features you create or edit.

Deactivate and Extract Geometry Commands

If you perform a difficult fillet operation, for example resulting in twisted faces, you can use the Deactivate and Extract Geometry commands to solve the difficulties.

Extract lets you generate separate elements from the initial geometry, without deleting the geometry.

When the app displays an error message that the operation cannot be properly performed, close the message box. A new dialog box appear that lets you deactivate feature and extract its geometry.

The feature is deactivated and is inaccessible in the tree. A node Extracted Geometry (Fillet.x) is also displayed in the tree.
