Modify tools for surface bodies

The tools in the Design workspace, in the Surface > Modify panel, let you modify surfaces in Fusion.

You can use the following commands to modify a surface:

• Press Pull
• Fillet
• Chamfer
• Trim
• Untrim
• Extend
• Stitch
• Unstitch
• Merge
• Reverse Normal
• Scale
• Split Face
• Split Body

Press Pull

The Press Pull command changes the size of faces, bodies, fillets, chamfers, holes, and other geometry. The exact behavior depends on the selected geometry.

When you use the Press Pull command, a Press Pull feature appears in the Timeline.

You can create a fillet or radius on edges, create extrusions from sketches, and offset existing faces.

Fillet

The Fillet command rounds the edges of a solid body, by adding material to interior edges and removing material from exterior edges.

When you create a fillet, a Fillet feature appears in the Timeline.

You can use the Press Pull command to modify existing fillets.

Chamfer

The Chamfer command bevels the edges of a solid body, by adding material to interior edges and removing material from exterior edges.

When you create a chamfer, a Chamfer feature appears in the Timeline.

You can use the Press Pull command to modify existing chamfers.

Trim

The Trim command splits intersecting surfaces and removes one or more sections of a surface or quilt.

You can use Trim to remove unwanted sections of intersected surfaces.

Untrim

The Untrim command extends trimmed surfaces and fills gaps, holes, or empty regions.

You select the surface to untrim, then select the untrim type. You can untrim all edges, internal edges, external edges, or manually select the edges you want to untrim.

Extend

The Extend command extends a face or surface by selecting one or more edges and moving them away from the face.

You can use Extend to create complex objects by manipulating surfaces.

Stitch

The Stitch command combines surfaces into a single quilt.

Unstitch

The Unstitch command separates the selected body into individual surfaces.

You can use Unstitch to break a quilted surface into multiple surfaces.

Merge

The Merge command combines surfaces within a single body into a quilt.

You can only use the Merge command within a single body and it is only available when design history is turned off.

Reverse Normal

The Reverse Normal command changes which side of a surface is considered positive.

A surface has two faces. One side of the surface is positive and one side is negative.

You can use Reverse Normal to repair imported models. During the translation process, the wrong orientation is sometimes assigned to faces.

Scale

The Scale command enlarges or reduces the size of surface bodies.

Split Face

The Split Face command divides faces on a surface body to add a draft, delete an area, or create features.

Split Body

The Split Body command divides a surface body into two surface bodies.
