Hi Michael T, thanks for posting the file.

So it appears that although there is no specific numeric limit, the ImportPointFile command is kind of slow to handle things because the script interacts a bit with MoI as every point is created. That's fine when there are a couple of hundred points but it bogs down quite a bit when there are 100,000 points like you've got in your file there.

It does seem to be loading the file though, just at a slow pace - I think that probably if you let it sit for an hour or so it will probably finish eventually. Note that it won't give any indication of progress during that time.

The speed of this import could be improved in the future, but I'm not sure what you would do with those 100,000 points inside of MoI though anyway?

- Michael
