When you select multiple blocks with the Adjust tool, the entries in the palette for size, position, and rotation become disabled. The tools available for adjusting multiple blocks are for aligning and sizing the blocks in relation to each other.

To multiple select blocks, click on a block with the Adjust tool. Hold the Shift key and continue to click on the blocks you want to include in your selection. The first selected block is the reference block for any alignment and sizing changes. It maintains its size and position; all others move or resize based on this block.

When using the Align tools, it’s possible the block you are aligning will move directly on top of the other block, depending on which Align tool you are using.
