You mean you want tiles to cover the filler.
1. If there is no problem with your block and it is well closed, then it should be no problem for you to choose the external filling as shown below.
2. If there are obvious problems with the tile, you can double-click the tile first, enter the tile editor, optimize the tile and then fill it.
3, PL line, frame the outline of the block, and then use TR command to trim and fill with PL line as the boundary.
4, can be solved by the above method, this method 4 is not used as much as possible, because the general operation is more troublesome. Specific operation, use the mask block command to input wipe out- box out the outline of the block-close and press enter-at this time, the block will be masked, select the mask block, and then put it under the block and fill it (that is, the DR command) to achieve the desired effect. When the tiles are complicated, this step is time-consuming.
