The customer is asking for an easy way to assign colors to faces/bodies when using "Style Palette", similar to how they used "Part Painter". They want to select a color and then click face by face. Currently, they only know how to assign colors using "Style Palette" by dragging a color/style to a face/body, resulting in dragging the same color multiple times.
SolutionUsing "Style Palette" in a similar way to "Part Painter" by selecting a color/style and then clicking on a face/body one after another is straightforward:
Double-Click on the color/style, then click on all the faces/bodies you wish to assign the colors to.
To assign a different color just double-click a new color/style. For quitting out of assigning colors just right-click anywhere on the screen.
