USing Defpoints layer and viewpoints

[qball]

I think what Remark was getting at was-

Defpoints is somehow associated to Layer 0. If you Isolate Defpoints, it turns off Layer 0 (along with all other layers). You can see Defpoints, but not select it until you turn Layer 0 back on.

Qball has it right, but the problem is that when you unisolate the layer it actually disappears from view altogether.

I think this is the problem that Alisonn is having.

Open layer manager both freeze and turn off layer 0 and also defpoints, Then unfreeze and turn them back on and do a regen.

You should now be able to select the defpoints layer again.

Don't know why it does this but it's happened to me many times.

i had this issue "invisible viewport" tried everything with layers etc...

turned out if i double clicked into the viewport to make it active, then maximized the viewport the view port frame suddenly became visible and therefore i could erase it.

just dumb luck.

You could try deleting defpoints layer using LAYDEL and hitting N for name. it will delete the layer and everything on it.
