When pasting the page, import the water jet file. If some areas appear gray and cannot be tiled with ceramic tiles, you can handle it according to the following steps:

1. Determine the area that cannot be filled on the filling page

2. Return to CAD, enter the BO shortcut key, then click on the area that cannot be filled, and then press the spacebar. Process the area that cannot be filled separately as a closed polyline.

3. Then enter the MY shortcut key, frame-select the water jet pattern, and then press the spacebar to convert the pattern into a surface area.
