I am working on a rather large file that started as a import of a Sketch-up based massing model. It is an area of Downtown Saint Paul, Minnesota. Initially the file was sluggish to non-responsive due the massive number of polygons it held, however, after extensive merge face commands, the base imported geometry begin to becomes noticeable quicker when rotating the view or navigating the model. Recently, something odd happened, the perspective viewport stopped displaying the entire model geometry at all. If i put the view into parallel it worked fine, and top, bottom, right and left all remained unaffected. I was able to get the geometry to reappear finally put now while i am rotating the view it suddenly disappears and will re-appear at random. I am new to this forum and a relatively new Rhino user so any help in this would be greatly appreciated. I am using a Mac beta version of Rhino 5 with today’s update installed currently, however this issue first occurred while running the file on my desk top PC at work which is running Rhino 5 with a grasshopper plug-in installed but not in use in this specific file. I have attached a screen shot of the described problem.
Below is a copy of my settings info for your reference.
