Building Frame

What is it?

A block with several placement modes to help you layout structures more easily
Also Lets you swap frames with blocks without breaking.

Controls (while looking at a placed Building Frame)
If you’re holding another Building Frame:
→ Shift + Right-click → Places frames on the opposite side of the face you clicked, stacking away from you
→ Ctrl + Right-click → Places frames adjacent to the frame you clicked, at the closest edge side

If you’re holding a solid, full block:
→ Shift + Right-click → Swap the lowest frame in that vertical stack: replaces the bottom frame with your held block (frame is returned).
→ Ctrl + Right-click → Swap in place: replaces the clicked frame with your held block. (frame is returned).

Notes

Fast break time
Configurable stack limit (default 12)

FAQ:

Q: Is this Scaffolding?
A: Sort of but no, It's not specifically for climbing but you might find it convenient for that, its more for building/placing
think of it as a reach extender if you like

Q: What is this good for?
A: I find it most useful for bridges and arches, it works well for a top-down building style
it saves me from making dirt scaffolding and pillars while building tall things
also good for group building - designer can layout and builders can fill in
