You can edit a room's shape, size and massing in 3D in Massing projects. Check the top right corner on the right panel to see if the project is of Massing or BIM mode.
To do this, click on the Move tool.
Double click on a face, edge or vertex that you want to move. A cyan indicator shows that the face, edge or vertex is selected to be edited.
Move the mouse to start moving the object. Coloured extension lines are shown when the movement is parallel to an axis, or an edge. In Massing mode, you are free to move faces, edges and vertices in any direction, in BIM mode these movements are restricted in the horizontal directions only.
Click again to place the face, edge or vertex in a new location, or enter a numerical distance for the move. You can place the edge or vertex accurately by snapping to a face, edge or vertex of another object. The snap indicator is yellow.
Colored indicators of vertex, edge or face
Cyan: Selected object
Yellow: Object that is snapped to another
Grey: Non-editable, but can be selected as a grip point for move
Colours of reference/ extension lines:
Red, Green, Blue: Parallel to the axes
Black: Edge movement perpendicular to itself
Magenta: aligned to its own edge or edge of another mass, also extension of edge
Violet: orthogonal/ perpendicular to vertex of same or another mass
