Modify floor slab sub element points relative to Base point

[graphite]

I am trying to modify a floor slab's sub element point relative to the project base point instead of the floor itself....anyone have any experience with this?

As far as I know that's just not how Floors work. You might need to do some math to work out the offset.

Thanks. I ended up tagging points to be modified with spot elevation set to project basepoint then modifying from there.

Good call! I didn't think of that.

You could also use a ramp, instead of a slab...
I find with the floor edit tool, that it's sometimes quite painful in that you need to calculate rather than just tell it I want a 1:100 fall.
These sort of calcs are of course pretty basic, but it could be more automated, something for the wishlist maybe.

@graphite - this is a fantastic tip. Great, great, great! :)
