CONVTOSOLID (Command)

Converts eligible 3D objects to 3D solids.

Find

The following prompt is displayed.

Select objects

Specifies one or more objects to convert to 3D solid objects.

Eligible objects include the following:

• 3D meshes that completely enclose a volume, called watertight meshes
• Surfaces that completely enclose a volume; you can use the SURFSCULPT command as an alternative
• Closed polylines and circles with a non-zero thickness property; wide polylines must have a uniform width

Mesh Considerations

When you convert mesh, you can specify whether the converted objects are smoothed or faceted, and whether the faces are merged. The smoothness and number of faces of the resulting 3D solid are controlled by the SMOOTHMESHCONVERT system variable. The following example shows a conversion to a smooth, optimized 3D solid.

The next example shows a conversion to a faceted 3D solid in which the faces are not merged or optimized.

Limitations

The following cases are limitations of this command. The selected objects

• Cannot include planar surfaces or regions with contiguous edges. For example, you cannot convert a 3D solid box that has been exploded into six regions.
• Cannot convert separate objects unless they enclose a volume without gaps. If the surfaces enclose a watertight area, you can convert to a solid with the SURFSCULPT command.

In these cases, use the SURFSCULPT command to convert the selected objects into a 3D solid.

Note: The DELOBJ system variable controls whether the geometry used to create 3D objects is automatically deleted when the new object is created or whether you are prompted to delete the objects.
