Very kind, thank you.

Indeed, the other constants are a little more depressing, so I rarely think of them, personally. I shall give it a miss until something (paid or not) appears - I'm always keen to adapt, but not at too much 'time cost', being self-employed and all. FYI Completely agree with your sig'.

TIG, thank you for taking the time to produce such an expansive reply, it's thoroughly appreciated. I do completely see the disadvantages to producing geometry with individual layers, it seems a good precise habit in CAD, isn't so helpful in SU! So far using the (wrong) technique I've been using, it hasn't caused any problems, but I completely appreciate it could create insanity. Herein I'll use Layer0 for geometry and layer names for components/groups and see how I get on - thank you again for clarifying this, really very much appreciated. Going back to my original question, I guess the request for this feature is mute by using the Layer0 technique - so that, answers that! Thank you again for your help. All the very best, Chris

Something I started doing was using MP4's, as the file size is much smaller - the sacrifice being the quality sometimes, but it's good enough for my needs. What you mentioned is what I did though, just stitch them together in some movie editing software. Hey ho!

I'll do my best to live up to frighteningly, small children have been known to run screaming from the room at my approach, could be my jokes though. Another tool you may want to look at is shape bender, very handy for making curved ramps and such.

If you want to try these. Might be a combination of the two. Use follow-me-and-Keep plugin on the the profile and center line. make the profile wider than the road at any point. Then drape the road edges (or intersect).
