There should be a way for users to make centrelines match to drawings graphically, not having to know the resolution of the scan and re-generate the centreline using a strange scale to make it fit...
Tunnel seems to do this very well. I *think* it works like this: (1) you select a point on the background image and the corresponding point on you drawing then tell tunnel to translate to make the two coincide. (2) you select the point which matches from (1), and another pair of corresponding points, then tell tunnel to rotate and scale around the point in (1) to make the other pair coincide. Provided tcl/tk can rotate and scale images, it shouldn't be too hard to implement.
I presume that this new centreline feature is only useful if you have your dataset in therion form, not survex form - right (i.e an imported 3d file can not be used to generate .xvi files)?
I'd assume so - the .3d file doesn't currently contain LRUD. Cheers, Olly
