In MicroStation CONNECT Edition (Update 13) and (Update 14), when opening a 3D model file, phantom lines are being displayed.In MicroStation V8i this is not happening.
This issue is file specific. It was found that an error occurred as BREP data and this has badly scaled up to 1E9.
By setting the configuration variable MS_FAST_LEGACY_WIREFRAME as 1, this issue is rectified.
Setting MS_FAST_LEGACY_WIREFRAME to 1 disables the display of wireframe silhouettes for SmartSolids
