The next step in designing the rubber grip for the air hockey paddle is to make the finger impressions. You can push and pull subobjects of a mesh (faces, edges, and vertices) to create that type of ergonomic/organic shape. However, the amount of detail that you can create is limited by the number of editable subobjects. Currently, the top of the rubber grip doesn't have enough editable subobjects to enable the detail required for the individual finger impressions.
The key for adding detail to a mesh it to have more editable subobjects in the area that needs detail. To do this, you can use the Refine tool. When you refine a mesh, AutoCAD converts the facets on the selected faces into editable faces with corresponding editable edges and vertices. I selected the subobjects at the top of the rubber grip, which included five faces, and then choose the Refine tool.
