Here are some tips to help you work faster and smarter in Sweet Home 3D. 
        
           
            | General | 
           
            |  | Use splitters displayed between the panes of the furniture 
                catalog, home furniture list, home plan and home 3D view, to resize 
                these panes. | 
          
            |  | To test Sweet Home 3D features without risk, remember that 
              all operations are undoable except the modification of imported 
                furniture in catalog.  | 
          
            |  | Numeric text fields handling numbers support mathematical expressions with the use of the operators + - * / ^ (power) 
            and the functions LN, LOG, EXP, SQR, SQRT, COS, SIN, TAN, ARCCOS, ARCSIN, ARCTAN. The result of the expression replaces 
            the entered text as soon as the focus is lost on the numeric text field, and the entered expression or value is displayed 
            in red as long as  it's not correct. | 
           
            | Furniture catalog | 
           
            |  | To add more than one piece 
                of furniture to home at a time, select more than one piece in 
                furniture catalog. | 
           
            |  | To open a category of furniture, double-click on it. | 
           
            |  | To modify an imported 
                piece of furniture, double-click on it. | 
           
            |  | When you have many pieces in your furniture catalog, display 
                the furniture catalog as a searchable 
                list. Its category combo box and search text field will help 
                you to find faster the pieces you want to add to plan. | 
           
            | Home furniture list | 
           
            |  | To sort home furniture, click on the column title matching 
                the sorting criterion. At the first click on a column title, the 
                furniture list will be sorted in ascending order, at the second 
                click on the same title, the furniture list will be sorted in 
                descending order, and at the third click on the same title, the 
                furniture list will be sorted in the order furniture was added 
                to home. | 
          
            |  | When the furniture list is not sorted, you may drag and drop selected 
            	items within the list to reorder them. | 
           
            |  | To reorder furniture list columns, drag and drop column titles. | 
           
            |  | To find where a piece of furniture is placed in the home plan, 
                select it in the furniture list. | 
           
            |  | To modify a piece of furniture, 
                double-click on it in the furniture list or in the home plan. | 
           
            |  | To modify more than one 
                piece of furniture at a time, select them in the furniture list 
                or in the home plan and choose Furniture > Modify.... | 
           
            |  | If you want to handle a set of pieces of furniture as one 
                piece, select them and choose Furniture > Group. A group 
                of pieces of furniture appears as one piece in the furniture list 
                and can be moved, resized and rotated as if it was one piece in 
                the plan. | 
          
            |  | If you want to move a piece (or a group) in an existing group, 
              select the piece, choose Edit > Cut, then select 
              the target group and choose Edit > Paste to group menu item. | 
           
            |  | When you choose Edit > Copy or Edit > Cut, 
                the selected objects in furniture list are also copied in clipboard 
                as a text at CSV format, that you may paste in a text editor or 
                a spreadsheet (this feature may not work under Linux). | 
           
            | Home plan | 
           
            |  | If you have a scanned image of your home plan at your disposal, 
                import it as a background image 
                of the plan first. This feature speeds up the drawing of walls. | 
           
            |  | To define precisely the scale of the imported background image, 
                enlarge the background image wizard pane. | 
           
            |  | If you want to set different colors on the side of a wall 
                shared by adjacent rooms, divide it in multiple segments at its 
                creation or by choosing Plan 
                > Split wall. | 
           
            |  | To build the sloping walls of a garret, choose 
                different heights at their start and end points. | 
           
            |  | When you choose Edit > Copy or Edit > Cut, 
                the selected objects in the plan are also copied in the clipboard 
                as an image, that you may paste in an other application (this 
                feature may not work under Linux). If you prefer an image of the 
                plan in a vector graphics format, choose Plan > Export to 
                SVG format... out of the menu. | 
          
            |  | To copy the style of an object on other objects of the same kind without displaying 
            their modification pane, select the object, choose Edit > Copy or Edit > Cut, 
            then select the objects you want to modify and choose Edit > Paste style menu item. | 
           
            |  | Use keyboard arrows to move precisely selected furniture. | 
           
            |  | Lock the base plan to select and arrange furniture 
                without being annoyed by the other kinds of objects displayed in 
                the plan. | 
           
            |  |  If you want to select an object which is hidden by other objects 
                in home plan, select it in the furniture list if it's a piece of furniture ; 
                you may also select any kind of object by placing the mouse cursor where the objects overlap, 
                then selecting the hidden object in the Select object contextual sub-menu. 
                Finally, you may also select an object in the plan with a selection rectangle that includes it, 
                into which you unselect the objects that hide it with a click while 
            	maintaining the shift key pressed. | 
          
            |  | If you want to deselect an object among the selected ones in the plan, click on it while 
            maintaining the shift key pressed. If the object is hidden by an other one, you may also  
            choose the hidden object in the Toggle selection contextual sub-menu that replaces the 
            Select object sub-menu when you press the shift key. | 
           
            |  | Use alignment lines to help you draw walls, rooms and dimension 
                lines precisely. | 
          
            |  | To move selected objects along the horizontal or vertical axes, use keyboard arrows or drag 
              and drop these objects, pressing the shift key after you start dragging them. | 
           
            |  | To duplicate selected objects in plan, drag and drop them while 
                keeping the Ctrl key pressed (or under macOS, the alt / option 
                key pressed). | 
           
            |  | Magnetism set in the preferences 
                pane can be temporarily toggled in the home plan, by pressing the  Alt key 
                under Windows, the cmd key under macOS or the Shift + Alt keys under Linux. | 
           
            |  | To help you draw walls and place furniture, change 
                the point of view and/or the transparency of walls in the 3D view 
                of your home. | 
           
            |  | To align furniture, select them and choose one of the items 
                Furniture > Align from the menu. Pieces of furniture 
                are aligned on the first selected piece. | 
           
            |  | To change the visible part of the plan without moving the 
                scroll bars that surround it, use panning mode by selecting Plan 
                > Pan menu item. When an other mode is activated in the 
                plan, this mode may be activated temporarily with the space key. | 
           
            |  | Choose Plan > Zoom in or Plan > Zoom out 
                to change the plan scale, or roll the mouse wheel forward or backward 
                while keeping the Ctrl key pressed (or under macOS, 
            the cmd key pressed). In the latter case, zoom is centered at the mouse cursor location. | 
           
            | Home 3D view | 
           
            |  | Choose 3D view > Display in separate window to place 
                the 3D view at a different place of the screen or a second monitor. 
                To attach the 3D view back to the main window, choose 3D view 
                > Display in main window or close the window displaying 
                the 3D view. | 
           
            |  | Press the shift key to increase the effect of mouse 
                moves and mouse wheel in the 3D view. | 
           
            |  | If you can't see some furniture in some rooms, modify 
                the transparency of walls. | 
           
            |  | If some walls, room floors or furniture are too bright, modify 
                light brightness. | 
           
            |  | If you don't know where the virtual visitor is located, roll 
                the mouse wheel with the mouse pointer in 3D view, it will automatically 
                select and show the virtual visitor in the home plan. | 
           
            |  | Use 3D view > Store point of view... to store the main points of view, where you'll be able 
                to go back directly later with the 3D view > Go to point of view menu. The time, date and 
                lens set in the photo creation pane box are also stored with a 
                point of view. If necessary, choose the 3D view > Delete points of view... menu item to select the 
                points of view you want to remove. | 
           
            |  | By default, the images generated at the two best quality levels 
                with the photo creation and 
                video creation panes are 
                illuminated with lights placed in the middle of the ceiling of 
                each room and the sun at daytime. 
                You may improve lighting by deselecting the Add ceiling lights 
                check box in these panes, changing the current hour / date, changing 
                compass orientation, adding other light sources and/or adjusting 
                their power. | 
           
            |  | You may  export the 3D view to 
                OBJ format and import the OBJ created file in an other 3D program 
                like Art of Illusion 
                or Blender. |
