Surface Fillet

Introduction

This topic will explain the Surface Fillet function, and the optionsfound in it.This topic will also describe where to find the function,provide quick steps and an example on how to use it, and provide links to related topics.

The Surface Fillet Function

The Fillet Surfaces function is used to join two separate surfaces witha defined radius between them using one of five trimming options.To ensuretangency, this function trims surfaces, but it does not extend them.

To open the Surface Fillet function:

  • In the Corners group, of the Create 3D tab, click Surface Fillet.

The parameters display in theData Entry Manager.

The Data Entry Parameters

Boundary Trim Type

The boundary options determine how the fillet is trimmed at the outerboundaries.The following image shows the two original surfaces as a referenceto the result shown below each option.

Original Surfaces

  • Blend - creates thefillet by trimming it and creating a tangent blend with the surfaceedges.

Blend

  • No Trim - creates thefillet between the two surfaces, but does not trim the outer edgesof the fillet.The resulting fillet exceeds the larger surface bythe radius amount.

No Trim

  • Minimal - creates thefillet using the smaller surface.

Minimal

  • Maximal - creates thefillet using the larger surface.

Maximal

  • Bevel - create the filletby trimming it and creating a beveled edge between the two surfaces.

Bevel

First Surface/Solid

 

(Delete) - removes the highlighted item from the list.
The list box will list the entity currently selected for the function.

Second Surface/Solid

 

(Delete) - removes the highlighted item from the list.
This list box will show the entity currently selected for the function.

Parameters

  • Radius - sets the radiusvalue of the fillet.

  • Tolerance - sets the tolerancefor the creation of the surface fillet.

  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps - Surface Fillet

  1. Open the function.

    The First Surface list is automatically given focus.

  2. Select the first surface

    The surface is added to the First Surface list.

    Focus is automatically placed on the Second Surface list.

  3. Select the second surface.

    The surface is added to the Second Surface list.

    The preview displays showing the result with default parameters.

  4. Update the parameters to achieve the desired result, which is visible in the preview.

  5. Click OK to confirm.

    The feature is added to the CAD Tree.

  6. Repeat as necessary.

  7. Click Cancel to confirm the function.

Example

This example will demonstrate how to use the Fillet Surface function.This example will have you:

  • Open a New Window
  • Adjust View
  • Create a Rectangular Plane
  • Move to the Front Plane
  • Create Another Rectangular Plane
  • Move to the Top Plane
  • Selecting the Geometry
  • Adjusting the Results


Note: In theimages below, both the Show Axis X-Yand Show Gnomon toggles have beendisabled in the Axis X-Y groupof the Settings Part > Displaydialog.

Part 1) Open a New Window and Adjust View

  1. In the Quick Access Toolbar, click New.

Part 2) Adjust the View

  1. Enter an ISO2 view by pressing Ctrl+7.

Part 3) Create a Rectangular Plane

  1. In the Surfaces group, of the Create 3D ribbon,click the down arrow under Planar, and select Rectangular Plane.

    The Rectangular Plane dialog opens in the Data Entry Manager.

    The Preview appears at X0, Y0, Z0.



  2. Click OKto confirm this surface.

    The surface is created in the graphics area and a Rectangular Plane feature is addedto the CADTree.


Part 4) Move to the Front Plane

  1. In the UCS Manager,click Front (X/Z) in order to create another surface on the Front Plane.

    The Front Plane highlights.

Part 5) Create Another Rectangular Plane

  1. In the Rectangular Plane dialog, set the Dimensions to:

    1. Width = 3.0000

    2. Height = 3.0000


The Preview updates.



  1. In the Base Pointgroup, change the Z valueto -1.0000.

    The Preview updates.



  2. Click OK toconfirm this surface.
    The surface is created in the graphics area and another RectangularPlane feature is added to the CADTree.


Part 6) Move to the Top Plane

  1. In the UCS Manager,click Top (X/Y).

    The Front Plane disappears.


Part 7) Selecting the Geometry

  1. In the Corners group, of the Create 3D tab, click Surface Fillet.

    The Fillet Surface dialog opens in the Data Entry Manager.

  2. Hover over the surface created on theFront Plane as shown in the image below.



  3. Select the surface.

    The surface is added to the First Surface/Solid list.



  4. Hover over the surface created on the TopPlane as shown in the image below.



  5. Select the surface.

    The surface is added to the Second Surface/Solid list and the Previewappears showing the result if the default Blend option is used.


Part 8) Adjusting the Results

  1. In the BoundaryTrim Type group, select NoTrim.

    The Preview updates to show the result if the No Trim option is used.



  2. In the BoundaryTrim Type group, select Minimal.

    The Preview updates to show the result if the Minimal option is used.



  3. In the BoundaryTrim Type group, select Maximal.

    The Preview updates to show the result if the Maximal option is used.



  4. In the BoundaryTrim Type group, select Bevel.

    The Preview updates to show the result if the Bevel option is used.



  5. In the Parameters group, change the Radius value to 0.5000.

    The Preview updates.



  6. Click OKto finalize the Surface Fillet.

    The surface fillet is created in the graphics area and another Fillet Surface featureis added to the CAD Tree.



  7. To end this function, click Cancel.

This concludes the example.
