You can run the LISTIMAGENAMESDWG command to do this. It will list all the images in a drawing, and tell you if it is a fill style image (bmpsty) or a symbol/inserted image (pictr2)

You can also use my custom command that list images sorted by addon. Note that the accompanying data file is a bit out of date, so a lot of files will be identified as unknown add-on.

Have you configured the glow/shadow effect to be in percent of view width perhaps? That really messes things up when you view from different zooms, or make different sizes exports.

That's great to hear. I think that is one of the main parts of a competition like this. Experminent, learn and have fun. They give you an opportunity to make something you wouldn't normally do.

Map looking great so far.

While $50 is dirt cheap for a commission, some people may find it a bit expensive for buying a digital copy of an existing map. I often back various kickstarters, and for that amount, you usually get 20-40 nice maps for that price.

There are no exact features like that, your options are basically

• The Snap grid. Set a rather large spacing, then counting won't be so much an issue. You'll probably want to make sure you have selected a dot type that is a bit large to notice them though. You can set the number of divisions high if you need snapping outside the visible grid. The snap grid is basically the guide feature in CC3+. Remember you can show the grid dots without having snap on.
• Set up a separate square grid in your map. Again, use large grid cells, and add the grid to a separate sheet and layer. You can then freeze the layer to make sure you don't manipulate the grid accidentally, and you can easily toggle it off/on or add a transparency effect to the sheet.
• Use the modifiers. The modifiers such as midpoint, endpoint and center helps you place things precisely.
