Fill

 

Use the FillClosed tool to fill in the selected region with the surrounding surface or solid. FillClosed can "heal" many cuts made into geometry, such as chamfers and rounds, subtractive revolves, protrusions, depressions, and regions removed by removing regions in the CombineClosed tool. When using FillClosed to fill a gusset, the bend geometry on which the gusset is defined remains intact.

The FillClosed tool can also be used to simplify surface edges and cap surfaces to form solids. You can select a combination of faces and edges to replace them with a single new face.

 

 

You can use the FillClosed tool in Sketch modeClosed to fill a loop of sketch curves that is almost closed, but that has multiple small gaps. If the gaps are too large, multiple error messages appear to show you where the gaps are. You can also use it to concatenate multiple sketched curves.

You can also use the FillClosed tool when editing a layout. FillClosed functionality is useful when you sketch faces across section lines, but do not want the section lines to split the surfaces when you switch to 3D.

When you change the geometry of a model, for example, the model’s length, height, or width, the model’s fill pattern will automatically update to correctly re-fill to the model’s new geometry.

Using the Fill tool

Click on one of the links below for detailed information about working with the FillClosed tool:

 

ClosedSketch and layout curves
ClosedVertices
ClosedEdges on surfaces
ClosedChamfers on surfaces
ClosedEdges on more than one face
ClosedSolids
ClosedFaces and edges or sketch curves
ClosedAny combination of sketch curves, layout curves, surface edges, and solid edges
ClosedMeshes

You can also use the Delete key to fill faces on a solid or surface.

To fill a region

  1. Select the edges that define a surface region, or the faces that define a region within or on a solid.

    You can select an object in the Structure treeClosed to simplify it.

    You can select faces and the FillClosed tool will automatically create a patch if you also select at least one edge.

  2. Click the FillClosed tool or press F.

To fill sketch or layout lines

  1. Select a closed or almost closed loop of sketch lines.

  2. Click the FillClosed tool or press F.

    If a gap is 1.5 times the length of the minor grid spacing on the sketch grid or less, the edges are extended to close the gap. If the gap is larger, a message appears in the status bar and the gap's endpoints flash.

    The mode is switched to 3D mode, and the filled loop becomes a surface.

    You can select the face of a solid when only the edge is displayed (such as in a drawing sheet view) using the scroll wheel. The edge becomes a slightly thicker line when the face is highlighted. If you fill lines in a layout, you can then pull the surface into 3D from the layout, but remain in edit layout mode after this action.

    You can fill lines and edges whether or not the sketched lines you want to fill were sketched in the same plane as the edges. (If the lines are imprinted on a face and become edges, filling those edges deletes them.)

Click the FillClosed tool in Sketch modeClosed to fill any closed or almost closed loops and switch to 3D mode.

Tool guides

The following tool guides help step you through the process. Use the Tab key to cycle through them. As soon as the tool guide switches, the cursor may change to reflect the active guide.

 

The Select tool guide is active by default. When this tool guide is active, you can select edges and faces to be filled. You can click an edge loop or use box-select to select multiple objects.

The Select Guide Curves tool guide allows you to select a guide curve.

The Complete tool guide generates the filled face.

Options

The following options are available in the Options panelClosed:

 

 

Examples

Simplifying edges

 

 

Simplifying edges across multiple faces

 

 

Filling with straight and curved edges

 

 

Filling with curved edges as guides

 

 

Capping a surface

 

 

Capping a surface that crosses multiple edges

 

 

Selecting internal edges to keep them after filling.

Selecting lines to simplify a surface by filling. Internal edges are removed.

Patch blendClosed with and without tangent extension. The Tangent extensionClosed option is selected on the left, and not selected on the right.

When selecting Guide Curves in the FillClosed tool, preview allows continued selection of multiple Guide Curves. This enables you to understand how the Guide Curves influence the geometry.

FillClosed works on multiple-selected, disconnected edge loops in surfaces. Use this as a shortcut instead of filling edge loops individually.
