Converting a polygon body to a CAD convergent-type sheet or solid body

You can use the Convergent Body From Body command to convert an existing polygon body to a CAD convergent-type body and store that new sheet or solid body in a part file. This capability is helpful when you want to make CAD modifications to a polygon body that is not associated to any underlying CAD geometry. For example, you can convert the following types of polygon bodies to convergent-type sheet or solid bodies:

• Solid or sheet polygon bodies that were created with the Face from Mesh command.

• Fluid bodies that were created with the Surface Wrap Recipe command.

You can create convergent-type polygon bodies from convergent-type CAD sheet and solid bodies. Convergent-type bodies are faceted representations of geometry in which edges and faces are based on tessellation rather than on parameterization. Convergent-type geometry is typically created by reverse engineering processes in which physical objects are scanned and translated into detailed 3D models as polygon facet data, such as STL format data. Additive manufacturing processes, for example, utilize this detailed facet data to both produce and inspect parts.

Designating a part for the new CAD convergent-type sheet or solid body

The software adds the new convergent-type sheet or solid body as an unparameterized feature to a CAD part file that you specify in the Convert Body from Body dialog box. You can store the convergent-type sheet or solid body:

• In the part file associated with the current FEM file.

• In a part file that is a component of a CAD part.

• In an entirely new part file.If you are working in a FEM file, the software creates a new CAD part and adds the CAD convergent-type sheet or solid body to that part as an unparameterized feature.If you are working in a component FEM in an assembly FEM file, the software creates a new CAD part.

• In an existing part file that you specify.

Associating the original polygon body to the CAD convergent-type sheet or solid body

Depending on where you choose to store the new convergent-type sheet or solid body, you can use the Associate to Convergent Body option to associate the polygon body to this convergent-type body. If there are changes to this new CAD convergent-type sheet or solid body in the CAD part file, the polygon body updates in the FEM file. However, the CAD convergent-type body does not update if there are changes to the polygon body.

Whether the Associate to Convergent Body option is available depends on both the option you select from the Target Part list and whether there is an existing part associated with the source polygon body.

Converting non-manifold polygon bodies

You can use the Convergent Body From Body command to convert both manifold and non-manifold polygon bodies to CAD convergent-type bodies. With a non-manifold body, the software automatically splits a single non-manifold polygon body into multiple CAD convergent-type bodies during the conversion process.
