This is a reply to an ANCIENT post, but I didn't see it answered on the list, so I figured I would post my solution to the problem of getting scraps and centerline to easily show up on the map together:

Create a map that consists of nothing but survey data. Make sure to give it a unique id.
Create a second map that consists of nothing but scrap data. Again, give it an id.
Create a third map that consists of the id of the first map you created and the id of the second map you created. Remember that the order in which you list the maps determines the order which they'll get drawn on your map. This third map needs its own id, of course.
In your thconfig file, make sure you select the third map you created. This is where the magic happens.
When you compile this, you should get a map that includes all of your finished scraps along with centerlines for everything else!

I hope this helps!!
