Sounds like you are not running with the latest update. The hammer icon should supply four options (small, medium, large, x-large), the single option for just large icons was replaced a while ago now, along with fixes to make things work better on high resolution displays.

Remember, you should always (re-)install the update after installing add-ons.

Easiest is to just install patch 3. Unless I remember incorrectly, Patch 3 doesn't require the CD, and should be the only one you need (see my previous answer above)

It looks to me that the wall has been turned into a smooth poly? Trace do have problem following smooth polys because the actual shape of a smooth poly is calculated from the nodes, and not actually going through the nodes. It does some attempt at a simple approximation of the main shape, but that rarely works out for complex entities.

This can only be changed by editing the drawing tool (Or better, make a copy, and edit the copy).

But, the best way to do it is to utilize a proper sheet naming scheme.

Almost all drawing tools look for sheets that STARTS with something in particular, for example, a drawing tool for the outside sheet will be set to draw on OUTSIDE*. That * is a wildcard, and means anything that starts with the text preceding it.

So, if the drawing tool is set to draw on OUTSIDE*, if your current sheet is called OUTSIDE VEGETATION for example, it will happily use that sheet instead of the default outside sheet. On the other hand, if your current sheet do NOT start with OUTSIDE, it will allways go to the default OUTSIDE sheet even if you have others starting with the word.

This same behavior applies to symbols as well.

Did you add that line of yours near those lights too? When exporting, CC3+ exports the map in sections, and it can't "see" what's outside the current section. I am guessing it is the same strange issue as above, and there isn't a "fix" in the section those lights happen to lie in.
