Snaptrude gives you two ways to reposition objects: the Move tool, which works on every object type and lets you pick an exact reference point and type a distance, and drag-to-move, where you simply click and drag a selected object. You can also line several objects up with Align objects. Moving works in both 2D and 3D views, in Design Mode and BIM Mode.

Move objects with the Move tool

Select the objects you want to move. To select several, hold Ctrl (Cmd on Mac) and click each one, or drag a selection rectangle.
Choose Move in the top toolbar, or press M. Snapping points appear on the vertices, edges and faces of the selection.
Click a point on the selection to use as the reference (base) point. Pick a corner or edge midpoint when you need to place the object precisely against something else.
Move the cursor in the direction you want. The selection snaps to nearby objects and to the X, Y and Z axes as you move.
Click at the destination, or type a distance and press Enter.

Tip: You can also activate Move first and then select. With the tool active, press Tab to cycle through overlapping objects under the cursor before you pick a reference point.

Lock the direction of a move

As you move, Snaptrude snaps to an axis when your cursor runs roughly parallel to it, in the same way as SketchUp. To force a direction, press an arrow key while moving to lock the move to the X, Y or Z axis. To move an exact distance in that direction, type the distance and press Enter.

How Move follows your view

Move is view-based, so the plane the selection travels on depends on how you're looking at the model:

In a top (plan) view, objects move across the current story.
In a front or elevation-like view, objects move vertically.
In a 3D view, objects move on the ground plane unless you're looking at it almost edge-on, in which case they move on a vertical plane.

Move doesn't snap to geometry hidden behind other objects, and spaces don't sink below the site when you move them.

Copy while moving

Start a move as above.
Press and hold Ctrl (Cmd on Mac). The tool switches to Copy, and any unfinished move is cancelled.
Pick a reference point and place the copy. If you release the key before placing it, the copy is cancelled.

When a copy starts, the command bar shows the Copy Type Selector, where you choose Instance (the default) or Unique. Instances stay linked, so editing one updates the others; unique copies are independent. Your choice is remembered until you reload the project. This works for spaces and BIM objects alike. The selector is unavailable for objects that don't support instancing.

Move, copy or rotate around a reference point

Move (M), Copy/Array (C) and Rotate (Q) all ask you to pick a reference point before the transformation. For Rotate, this point is the pivot the selection turns around. Choosing a specific corner, edge or snap point means the selection lands exactly where you need it, without nudging it afterwards.

Tip: To turn a selection by 90 degrees without the Rotate tool, press Spacebar or choose Rotate 90° from the Right-click menu. The selection turns 90 degrees clockwise; this doesn't apply to doors, windows, voids or locked objects.

Drag to move

With the Select tool active, click a face, edge or vertex of the object and keep holding the mouse button.
Drag the object to its new position. You can lock an axis with the arrow keys or type a distance, as with the Move tool.
Release the mouse button to drop it.

To drag several objects together, select them all first, then click and drag any one of them.

Drag-to-move works on spaces, walls, columns, beams, doors and windows, furniture, staircases and masses. Use the Move tool for CAD, PDF and image underlays, topography, Flooring, Floor Slab, ceilings, roofs and site spaces.

Align objects

Select two or more objects you want to line up.
Choose Align.
Pick how the objects should line up.

Align also works on masses. Alongside Align, the Replace with option lets you replace the selected objects with a different object.

Troubleshooting

The object won't snap where I expect: hold Alt (Option on Mac) to turn snaps off temporarily, or orbit so the target point is visible. Move doesn't snap to hidden geometry.
The object moves up instead of sideways: you're looking at the ground plane almost edge-on. Switch to a plan view or orbit to a higher angle.
I can't drag an underlay or a slab: these objects don't support drag-to-move. Select the object and use Move (M).
I picked the wrong object in a stack: press Tab to cycle overlapping objects (Shift + Tab to go back).
