"When applying texture maps as a bump map you can see and control the result in the graphics area. When in Shading With Reflections mode you can visualize the effect of procedural bump maps such as Rough or Cast. You can apply realistic textures and bump maps to the geometry. For example you may want to assign an appearance of tire tracks to a tire. Open the tire separately and assign an appearance to it such as rubber. Then, assign a new appearance with a texture map of a tire tread to selected surfaces of the tire. You can make adjustments such as changing the scale, changing to cylindrical mapping, and then changing the height of the bump. The texture map is visible on the model. In the assembly you see the tire and the tread. If you select View ▶ Shading with Reflections, you see the tread with the reflections. In addition to bump maps, you can also for example, alter the body by adding a Rough bump. If you change the scale and the size of the bump, you can see the effect appearing on the car body. "

You can use Substitute Faces to replace one or more surfaces

"Changing a product design and exploring new ideas is a technical challenge, especially when developing complex systems with many interdependent components. Typically, this process involves manual backup of models to folders, repeatedly closing and cleaning the PTC Creo Parametric session, and manually revisiting and reviewing massive iterations until making a decision. Design Exploration Extension helps to streamline the process of evaluating new designs and deciding on changes to the design. In PTC Creo Parametric, open a model. To start exploring new ideas click File ▶ Manage Session ▶ Design Exploration session ▶ Start to open a Design Exploration session and then in the Name box, type a name for the session. This is where all your exploration ideas are stored. A snapshot of your PTC Creo Parametric session content is saved to the checkpoint Pre-modified. You can now start to experiment with your design without risking the original models. As you make changes, you can add checkpoints. Each checkpoint stores only the incremental model changes since the last checkpoint. For your additional clarification, you can provide a checkpoint name, comments, and also define keywords to use for later search. You can switch between checkpoints without losing information. In your Design Exploration session, multiple model iterations are replaced as they are captured in the active checkpoint. That eliminates the need to manually backup models to different locations or clean up your session each time you want to switch between different design iterations. When manipulating models in an active checkpoint that already has successors, you can create new checkpoint sequences and form different branches. With branching, you can develop and evaluate multiple ideas, simultaneously. Every branch represents a different direction of the design. If some checkpoints along the branch are no longer needed you can delete them without losing information in a later iteration. If you shorten the branch, iterations from a deleted checkpoint are merged into its successor. You can also delete a complete branch. You can navigate the Checkpoints Tree in Tree view, or in Timeline view. Checkpoints along the active path appear in a darker font making it easier to locate earlier checkpoints in same sequence. You can browse different branches that appear in a lighter grey font. When you are ready to make a decision, you can accept the checkpoint with the chosen design and then return to the PTC Creo Parametric session. You can keep entire session data in the specified .TMZ file. All model iterations along the path to this checkpoint will be applied to the models from which you started the Design Exploration session. "
