I agree, sometimes the door cutter and door placement is hampered by the grid. Most likely, I have it on the wrong layer or something. I hide and freeze the grid when I do doors and use the cutter for openings.

Another update. Map part 2. As you can see, the roads and walls don't match with part 1 and part 8. I'll fix that later.

the parts, partial map.

simple and quick dungeon

1) main entrance. 7.5 feet x 14 feet.

skeletal remains on the left.

2) blood trail leads off to room 3.

23' x 60' x 10' high.

Mosaic floor shows former grandeur. Edges are squares, looks like it has been recently worked on. No sign of tools.

Opening to room 3 to the left. Wood door to room 4, which has 2 ogres.

Stone door to the right that leads to a second door into room 6.

3) 31' x 25' x 12' high

4 skeletons and a dead body of a lone adventurer, or maybe a farmer who found a hole in his land. Two piles of hand cut boards.

4) 40' x 56' x 20' high

2 ogres in a maze of wood and stone walls. The walls vary from 3' to 5' in height.

5) 40' x 55' x 15' high

Sacks could hold grain, but why do they rattle when moved ?

Debris with skeletons, and a number of skulls, in front of the ballista. Broken furniture. Rough surface carved out, never finished.

Wood pallisades, 6' high.

Two small chests behind the ballista with reloads magically. Are the bolts deadly ? Or just illusions ?

Wood debris.

6) 32' x 27' x 15' A former Throne room ? Then why the pit ?

Second door coming from room 2. This second door has holes from vision, and spears.

The mosaic is much nicer and looks recently inlaid. No sign of tools.

Six wooden chairs and a throne. No remains in the pit.

7) 8' x 12' x 10' A room behind a secret door.

Rocks block access to a chest.

Sparsely populated with debris and a few skeletons. Blood trail from left entrance. Some chests behind a secret door lower part of the map. Loosely based on a watabou (spelling ?) map.

Be careful of the ballista !

Before I started Crestar, I noticed the store players in my area would argue with the DM on what was in a published world, and what wasn't. So I decided to use my own.
