But if you want to do a constant width path, why not use a wide smooth path from the start? You can apply fills and sheet effects to that like to a polygon.

If you want to keep one side of the polygon you've already drawn, use the Break command (BREAK) to remove the other side, then change the width and perhaps move it a bit.

The problem seem to the brightness of the Texturize effect, which you've set to 100%. That removes all the shadow. Try setting it to 80% or something like that.

That looks a bit like an installation with insufficient rights (non-admin). Are you running CC3+ on a Windows account with reduced rights?

As a first thing, I'd try to run the latest update for CC3+ (update 28) . Download it from your registration page, right-click the file and choose "Run as Administrator" to execute it. Does that help?

If not, I would recommend a reinstall, making sure you also run the setup for CC3+ by right-clicking the file and choosing "Run as administrator" to execute it.

The water level in FT3+ is world-wide. High altitude lakes or below sea-level land is not something FT does, sorry.

EDIT: This was wrong, see jslayton's answer below.

Like Remy says, proper code-signing is effectively essential for a reputable software publisher. We changed certificate providers recently, and of course they need to authenticate you to make sure that you are really the company you claim to be. That took a little longer than expected and clashed with GenCon. Rather then postpone the Annual entirely, I opted to release it unsigned at first. It is now updated (also with fixes to the metric template) and properly code-signed.
