Here are some basic point bugs in LD2004 that I was really hoping would be fixed in SP2, but weren't:
1) Point Renumber is broken. If your target point range overlaps the source point range, AutoCAD gets ALL confused. So, if (for example) you need to add a point between points 3 and 4, and you have 10 points total, you have to first renumber points 4-10 with something like +100, then renumber points 104-110 with a -99. (This means you first need to list available point numbers, identify a suitable blank range, etc.) Now you can finally create a new point 4, and you're left with points 1-11. Back when Point Renumber was a Softdesk program, you could simply tell it to renumber points 4-10 with a +1, and everything was kosher.
2) Import Points doesn't know how to cancel. If you start it importing the wrong file, and get one of those "Point XXX exists; do you want to replace, replace all, ignore, ignore all, cancel" dialogue boxes, hitting "Cancel" does the same thing as hitting "Replace All". Now your project is all buggered. Hope you have a recent backup.
3) Alignments->Display Points doesn't use point groups(!) or the handy point dialogue box that most of the point commands can now use, and craps out if you specify a point range that includes a gap. For example, if you want to display points 1-100 by station and offset, but you don't have a point number 28 in the database, you'll only get points 1-27 in your output. You have to explicitly tell Display Points to display points "1-27,29-100" in order to get what you want. This is a real pain if you have a lot of gaps, especially since you also can't use the point group you probably already created.
