Mesh modification

The tools in the Design > Mesh > Modify panel let you modify mesh bodies in Fusion.

You can use the following commands to modify mesh bodies:

Direct Edit

The Direct Edit command creates a mesh base feature that you can edit directly.

Select the mesh body to edit. A mesh base feature displays on the timeline and you can make local modifications to the mesh body without capturing the changes in the parametric history of the design.

Note: Face groups are the smallest selectable entity in Parametric Modeling mode. Use Direct Edit to select and modify individual faces.

direct edit example

Remesh

The Remesh command refines or coarsens faces on a mesh body or face groups.

You select a mesh body or face groups on a mesh body, then adjust the settings to regenerate the mesh faces.

Reduce

The Reduce command reduces the number of faces on a mesh body to minimize complexity.

You select a mesh body or face groups, select a reduction target, then adjust the settings to reduce the number of mesh faces.

reduce example

Plane Cut

The Plane Cut command uses a plane to trim or split a mesh body.

You select a mesh body, then select and position the cutting plane. The cut can trim the body, split the body into multiple bodies, or split the faces only. For the Trim and Split Body cut types, select a fill type to generate watertight bodies.

Shell

The Shell command hollows the interior of a mesh body.

You select a mesh body, then adjust the direction and thickness to hollow the interior volume.

Combine

The Combine command joins, intersects, cuts, or merges two or more mesh bodies to create a single mesh body.

You select the target body, select one or more tool bodies to combine with the target body, then select the operation to use to combine the bodies together. Overlapping boundary edges are stitched. You can also choose to create a new component to contain the combined bodies or keep a copy of the original bodies.

Smooth

The Smooth command smooths rough or creased regions on a mesh body.

Select a mesh body or face groups, select a smoothing type, then adjust the smoothness and scale to smooth rough or creased regions.

Reverse Normal

The Reverse Normal command reverses the normal direction of the selected faces on a mesh body.

Select faces on a mesh body to reverse their normal direction. To select individual faces, use Direct Edit.

Erase And Fill

The Erase And Fill command removes and replaces faces on a mesh body to fill holes and repair regions.

Select the boundary of faces around a hole to fill or select the faces of a region to remove and replace.

Note: Erase And Fill is only available in Direct Modeling mode.

Separate

The Separate command separates regions of a mesh body into independent mesh bodies.

Select a separation type, then select a mesh body or face groups to separate into individual bodies. You can also choose to keep a copy of the original mesh body.

Move/Copy

The Move/Copy command moves or copies selected faces, bodies, sketches, or construction geometry a specified distance or angle.

Select the objects to move or copy, then specify the distance and angle.

Scale Mesh

The Scale Mesh command scales mesh bodies from a reference point.

Select mesh bodies, select a reference point to scale from and a scale type, then specify the scale factor to scale the mesh bodies.

Delete

The Delete command permanently deletes selected objects, and everything related to them, from the design.

Select components, bodies, sketches, and construction objects to delete.

Note: The Delete command does not create a feature in the timeline. Deleted objects cannot be restored parametrically. If you want to preserve parametric history, use the Remove command instead.

Convert Mesh

The Convert Mesh command converts a mesh body to a solid or surface body.

Select the mesh body to convert, then select the conversion type: faceted, prismatic, or organic.

Physical Material

The Physical Material command lets you apply color and engineering properties to components and bodies.

Appearance

The Appearance command lets you apply color to components, bodies, and faces.

Change Parameters

The Change Parameters command lets you create equations and relationships to control the size of objects in your design.

Compute All

The Compute All command computes all of the parameters in your design.
