Hopefully a quickie here... I'm working on a routine to reposition Saved Views in a file. The SavedViewElement has a method "RotateAboutZ" but it can't be applied as SavedViewElement is a non-graphical element. Can someone point out a quick way of getting this to work? If not, I guess I'll just need to start to get my head around the maths for rotating the CameraTarget & CameraPosition properties manually .
Thanks, I hope
NigelPDavies said:The SavedViewElement has a method ...
The problem arises because the SavedViewElement inherits a number of properties & methods from Element. Not all properties & methods are applicable to a non-graphic element, but there's no way in VBA of removing those. The documentation doesn't tell you which methods are not applicable.
Using VBA, I don't think there is a way to do what you want. As far as I can see, we need the C++ MicroStationAPI to manipulate NamedView information. You can't get at the MicroStationAPI from VBA because VBA doesn't understand C++.
There may be a naming confusion: saved views have been around for donkey's years (they were available in MicroStation/J). Named views are more recent, and store more information (such as camera position) than a saved view. I think the VBA object is the older saved view.

In keeping with Jon's suggestion of using some native code / MDL to help I have this little project that I worked on for a user that exposes out some functionality via CExpression calls. If you build this dll and load it you can manipulate the rotation of a named/saved view by passing in the name and the updated value for either the 3d or 2d rotation.
