Modify tools and grips

Every tool here makes one edit with one undo step. Each is also a command the agent runs, so a picked value and a typed one make the same change.

Move, duplicate and delete

• Select something and type a length: Move opens with what you typed in East. Tab goes to North. Return applies, Esc cancels. Or press M or Return to open it empty.
• In the Move fields, ↑ and ↓ step by an inch (⇧: a foot).
• The arrow keys nudge the selection 1″, ⇧ and an arrow 1′.
• Duplicate (⌘D) copies the selection a foot east; Delete (⌫) removes it.

A door or window moves its wall. To slide a door along its wall, use its grip (below).

Rotate, mirror, scale, align, offset and array

All are on the Tools menu. ⌘K also finds each by its AutoCAD alias. Points snap as Measure's do, and the selection is drawn where it would land until the last pick.

Key	Tool	Alias	How
⌥⇧T	Rotate	RO	Click the base point, then a second point, or type an angle.
⌥⇧M	Mirror	MI	Click two points on the mirror line. Keep the original mirrors a copy.
⌥⇧D	Scale	SC	Click the base point, then type a factor, or click a reference point and where it goes.
⌥⇧A	Align	AL	Click a source point and where it goes, then a second pair.
⌥⇧O	Offset	O	One wall: click the side, or type the distance.
⌥⇧Y	Array	AR	Type rows, columns and spacing; or click a centre for a polar array and type the count and the angle to fill. Counts include the original.

Limit. Scale stretches walls along their length, never their thickness; columns, doors and windows keep their size. A room cannot be offset, since the copy would overlap it.

Anything a tool can't take is named in the message, with what to select instead.

Trim, extend, corner, split and join walls

These pick walls directly, not a selection:

Key	Tool	Alias	How
⌥⇧K	Trim	TR	Click the boundary wall, then the part of a wall to cut away. The part it loses is drawn dashed as you hover.
⌥⇧H	Extend	EX	Click the boundary wall, then a wall near the end to stretch to it.
⌥⇧V	Corner	F	Click two walls; both stop where their lines meet.
⌥⇧I	Split Wall	BR, SP	Click a wall where it should split. Doors and windows go with their part.
⌥⇧J	Join Walls	J	Click the wall that stays, then one in line with it.

Limit. Trim only cuts an end of a wall: split it first to trim a middle. A split through a door or window is refused, and so is a join of walls that are not in line or not the same thickness.

Clip

Reshape with grips

With Select or Move on, one selected element shows grips in plan:

• Wall: an end grip at each end and a middle grip that moves it.
• Door or window: a centre grip that slides it along its wall, and a grip on each jamb that resizes it about its centre.
• Room, mass or slab: a grip at each corner. A room also has a grip in the middle of each edge.
• Column: a centre grip that moves it.

1. Hover a grip to light it, then drag it. It snaps as Measure does, and the length it changes shows beside it.
2. To set that length exactly, type it during the drag (a length, a parameter or an expression). Tab moves to the next length.
3. Release to apply. Esc drops the drag.

Limit. Grips are plan only, and show for one selected element at a time. A wall's thickness has no grip.
