You can switch between displaying the geometry of the part instance and the meshed representation of the same instance by clicking the Show native mesh icon located in the Visible Objects toolbar.
You can use the Show native mesh tool in any of the assembly-related modules to switch between displaying the geometry of the assembly and a meshed representation of the assembly. Abaqus/CAE displays the meshed representation of both independent and dependent part instances in the assembly (assuming that you have created the appropriate meshes).
Toggling between the geometry of a part and its meshed representation using the Show native mesh tool allows you to see how closely the mesh follows the geometry. The tool also allows you to see how Abaqus/CAE incorporated virtual topology into the mesh. In addition, you may find it useful to click on the Show native mesh tool in the Job module. You can then confirm that the entire assembly has been meshed correctly before you submit a job for analysis.
The display of any orphan elements in the model is unaffected by this tool; orphan elements are displayed regardless of whether you display the geometry or elements for the native portion of part instances.
