We're having a problem with one of our VW2008 files.
Typically, we set up our files with various classes for different building components and use the class visibility settings to toggle the classes on and off; sometimes selecting 'active only' etc., to view parts of the building model in isolation and then going back to show/snap others or show/snap/modify others to view the model as a whole.
Usually, we have no issues with this and find VW to be an excellent tool for building our 3D models; however, we have a file that has developed a strange problem where the model view will not update when the class visibility settings are changed. For example, we might be looking at our model in an isometric view with open GL rendering, we select our 'roofing' class as the active class to view our roof faces in isolation. When the visibility settings are changed to 'active only', ordinarily, everything disappears except our roof faces, and we go about our work. For some reason we cannot figure out, what we end up seeing is instead the very same view that we had before the visibility setting was changed. The really odd thing is that the setting has changed, only the screen has not been 'refreshed' or 'updated'; that is, when we try to render the screen again with open GL, nothing changes; however, when we render the screen with a different rendering method (say final vectorworks), the screen updates, and voila, there are our roof faces in isolation. None of this seems to happen in wireframe, which leads us to believe it is a rendering problem.
Our current workaround is to simply re-render the view with a different rendering method, but it is frustrating and we would like to correct this issue.
We've looked at other VW files with 3D models in our office and find that they are behaving normally with no rendering issues, so it does not appear to be our application installation that is causing the issue. The issue seems to be isolated to this particular file and copies of it.
Has anyone else experienced this problem or have a suggestion or remedy? Any help would be greatly appreciated.
Scratching our heads,
