Just recently I have been doing lot of surface intersections and curve intersects etc. However a plane is an inifinate plane when it needs to be, but also a surface when it needs to be. But in one of the intersect options (surface/curve), you can not select a plane, when it says select surface? Yet in other options it'll say 'select surface' and will allow the selection of a plane.


How is this so? I then need to use surface cut, which works and will intersect a plane and a curve to give me a point.

To me a plane is a plane, not a surface (I might be alone on this one?). If it were a surface I should be able to right click and change object to surface, and it would fill in and become.......a surface?

Anybody else have any views on this?

Cheers
