Therik:
Option 1: w/o a leader--
If you just need to place the block near the hole without pointing a leader line to the hole, just click inside the view and select insert from the pulldown menu, annotation, block. The block may not be placed exactly where you clicked, but it is attached to that view. Just move the block where you like it.
Option 2: w/ a leader--
If you want a leader line pointing to the hole, select the edge of the hole and then select insert from the pulldown menu, annotation, block. A leader will be attached to the point where you selected the edge. Make sure you get it right the first time because you can move the leader location. The actual block may be anywhere on the screen again, just move it to where you want to go. Again, the leader stays anchored to the same location as orginally selected and you can't adjust it.
FYI:
If you would open up the block file, you'll see that it is on a sheet of paper. When you click on a point in a drawing to insert a block, that becomes the lower left corner of the paper of the block file. Following me? So, if your block happens to be located in the upper right corner of a B size sheet of paper and you're inserting it into an A size drawing, then the block won't appear on your drawing and a fit view won't find it. You will have to manually "scroll" view out to see it. The block will be located the distance (about 17X11 in this example) away from the point that you selected to place the block.
To remedy this, shrink the paper size in the block file to just larger than your extents of your block. Move the block contents to the lower left corner of the paper and save. From then on, when you insert a block, it should appear very close to the location that you selected.
