ref point/planes

[monchie]

Hello,

I have a couple of questions regarding ref. points/planes.

1. How do you delete re. points/planes when you do not need it anymore.

* I've tried opening the model in text file but still the re. points/planes are still there.

2. Can you replicate slabs in ref. planes?

*I do not see any facilities to replicate slabs i vertical fashion(up or down), all I see is replicating slabs in x/y axis, nothing
on the z axis, am I correct on this.

Any ideas will be greatly appreciated.
