Rotate & Flip: overview

Rotate & Flip turns and mirrors a selection in place. Native ROTATE and MIRROR treat a multi-object selection as one group swinging about a single base point or mirror line; these commands transform every object where it sits, around its own pivot: the insertion point for a block, the geometric centre for everything else.

There is no base point to pick and no mirror line to draw.

Three ways to run every command

• Ribbon: the Rotate/Flip panel on the MD Automation tab, with a Rotate and a Flip drop-down. The button face remembers the last command you used.
• Right-click: select objects, right-click, and open the Rotate/Flip submenu.
• Command line: type the command name.

Command reference

Command	What it does
MDROTATECW	Rotate each selected object clockwise by the configured angle (90° by default), around its own pivot.
MDROTATECCW	The same, counterclockwise.
MDFLIPH	Flip each object across its own vertical axis (left–right), in place. Swaps Left ↔ Right attribute justification.
MDFLIPV	Flip each object across its own horizontal axis (top–bottom), in place. Swaps Top ↔ Bottom justification.
MDROTATEFLIPSETTINGS	Walk every preference in one pass; see Settings below.

Settings

MDROTATEFLIPSETTINGS walks each preference in turn, defaulting to its current value, and writes once at the end, so a run you abandon halfway changes nothing.

Setting	Controls	Default
Rotation angle	Degrees per MDROTATECW / MDROTATECCW. Flips are unaffected.	90
Keep transformed objects selected	Whether the objects stay selected afterwards, so Enter or Space repeats against the same set.	Yes
Use dynamic rotation	Whether rotating drives a block’s own rotation action instead of moving geometry.	Yes
Use dynamic flip	Whether flipping toggles a block’s own flip parameter instead of mirroring geometry.	Yes

Good to know

• The selection survives: unless you turn it off, the transformed objects stay selected, so pressing Enter or Space runs the command again on the same set. Useful for stepping a symbol round 90° at a time.
