Havent posted for a long time, this is goig back a while as i havent had time to use maya for a long time and i want to get back into it.

I am having issues when trying to detatch a surface on a nurbs model, when i select isoparms and click detatch, it doesnt work i do this twice - all it seems to do is create another isoparm instead.

Any info would be great, thanks in advance.
