Hi Anthony re: Trim -

> I have a circle I'm trying to trim with two points.

Could you post the particular circle and the 2 points in a 3DM file so I can take a look at your specific case?

Trim does work in general with a circle and 2 points - for example here I've created a circle and 2 points on it, and used the Trim command to cut away a part of it:







If it doesn't work from you possibly the points are not on the circle or something like that? It's hard for me to know what the issue might be without seeing the model file though.
