Dev Replace Tool

[GhostZombie]

Sorry if this is in the wrong area, this is my 1st post.  Is there any information on the Dev Replace Tool for Alpha 19.6 (b8)?  I have watched videos, but None of them Explain how to really use it.  All the videos show the person going thru the Steps but not which Keys/Mouse Buttons to use?

 

I am trying to replace a selected area with Concrete Blocks. and it won't work.  I can Clear an area to Air but not replace Dirt (Selected area 2H x 10W x 10L) with Concrete.

 

Any suggestions and/or advice will be greatly appreciated.

Left click on the block type you want to copy.  If done correctly it will list the block name in the bottom right corner of your screen.

 

If you want to replace all blocks within a selection, you will want to make sure you hold down the "R" key and toggle on the option.  There is also an option in the radial menu to keep the paint used on the highlighted blocks if desired.

 Thank you Laz Man that worked?  Do you know of anyway to fix the Missing Water blocks in a lake?  Since this tool does not work on Water or Air?
