In V7 Workmode, reference clip boundary (or masks) that contain arcs orcurves are not retaining after file save.(The same clip worked in MicroStation V7/J)
Clip is beyond V7 limit of 101 vertices.Reason it worked in V7/J:Due to the 101 vertex limit in V7 clips (for both boundaries and masks),MicroStation J will "stroke" the curved elements into lines. Since V8has a higher limit (5000), the "stroke" process is not needed. Eventhough it is a V7 file (V7 Workmode), the reference system does notchange the clipping process.Solution:Use lines segments instead of true arcs or curves to clip the reference.The "Drop curves" tool could also be used to "stroke" the curves intolines.
