Thanks Brian. I tried this with a test file of 5000 points copied from the original text file and pasted into a new file, and it worked. But I couldn’t find any way to connect all the points automatically to make an object. I tried the file with over a million points, and after 15 minutes the Mac beachball was still spinning, and Cinema was “not responding,” according to the message I got when I decided to force quit. If I have to connect them all by hand anyway, it’s simply not going to happen, unless someone knows of a way to automatically skin the points to make polygons.
Thanks for your help and input.
Jack
