Modifying evelation heights of line string contours

[vinceLADS08]

I am currently working with Microstation v8 xm and i have a data set with 3d contours. the contours have been converted to line string (as per spec) i have noticed that the elevation of each edited contour, either by extending line, inserting vertices or even moving the contour to another position will change its elevation height to +/-10000m. My worksheet is set at a rotation view of 45deg, but surly this can only affect xy not z direction. I am able to edit the elevation depth using the info tool but this just seems to affect the position of the contour rather than the height. When i view my worksheet in the isometric view (45deg sideview) you can see the elevation spikes of my dataset. Also, working on top view seems to have this problem too. One method is to export the contours as .dwg format and amending the elevation using terramodel, but surely there should be some other way to edit contour heights without affecting their position?

Any help would be greatly appreciated.

This is the one and only thing that I prefer autocad for. My old company had programmers write a "fix Z" macro for just this. I'll do some research and see if it's available somewhere.

At first glance I think that the macro was written to set your active depth to what your Z value should be, then flatten your selection to that view.

Here's some reference material that may be helpful.

I've downloaded Civil Tool which allowed me to modify contours without affecting the z plan vise verser when amending the elevation height the xy position of an element will not change.

Much appreciated
