DR can only make your block on top of the fill pattern, but not cover the fill
You mean, I think you want the block to cover the fill.
1, if there is nothing wrong with your block, closed very well, when the initial fill, as shown below, select the external fill should not be a problem
2, if there are obvious problems with the block, you can double-click on the block, go to the block editor, optimize the block and then carry out the fill operation above
3, PL line, box out the block outline, and then Use the TR command to the PL line as a boundary, fill on the line to trim
4, can be solved with the above approach, this method 4 try not to use, because the general operation is more troublesome. Specific operations, the use of masking block command input WIPEOUT - the outline of the box out of the block - closed after the return - at this time the block will be masked, select the masking block, and then put the It is placed under the block, fill above (that is, the DR command), you can achieve the desired effect. When the block is more complex, this step is time-consuming
