Buggy Clip/Add surface

[Damon Design]

I think I mentioned this once before but I am generally having a grand ole' time in VW08 context clicking clip and add surface (though I had incorporated this in my workspace previously) on edit group-roof faces primarily- and sometimes this function simply refuses to work. Add surface command removes everything and clip surface removes all of the bottom object except for the area beneath the clipping surface?!

It does the same thing if I use the menu commands instead of context clipping.

Is this just my machine or does anyone else experience this?

Does the magic of Parasolids in 09 solve this?

Thanks

Yes I have noted same problems some times specially after repeated edits, the whole object disappears specially with a polyline, changing the object to polygon gives me some peace some times otherwise close down & start again.

i have had this problem too, but i have found that moving some of the end vertices a tiny bit rectifies the problem, but only sometimes. I have found that when this doesnt work i have to re-draw the object and then for some strange reason it work again.
