QUESTION

How does Home Designer calculate living area?

ANSWER

The Living Area label is an automatically generated text object that reports the area of the current floor specified as living space. This label is created as soon as a room area is defined by walls and/or railings and is recalculated every time you add, remove, resize, or redefine a room. If multiple buildings are created, each will have its own Living Area label.

By default, interior type rooms are defined as part of this calculation, while exterior and hybrid type rooms are not. Some of the room types that aren't included in the Living Area calculation are: Attic, Court, Deck, Garage, Open Below, and Porch. In addition, rooms with a Rough Ceiling height less than 48" (1200 mm) are excluded from this calculation by default. Regardless of the room type or height, you can specify whether a room or room type is included in this calculation using the Room Specification dialog.

You can choose to include or exclude a room from the Living Area calculation by utilizing the settings in the Room Specification dialog.

To manually include or exclude a room from the Living Area calculation

1. Using the Select Objects  tool, select a room and then click on the Open Object edit tool.
   
   
   
2. On the General panel of the Room Specification dialog that opens, choose the option to Include in Total Living Area Calculation or to Exclude from Total Living Area Calculation.
   
   
   
   
   
3. Click OK to save the changes.

To calculate the area of the plan's footprint

1. Once your floor plan is finalized, navigate to the floor that you would like to calculate the footprint of.
   
   
   
2. Next, select CAD> Draw Polyline .
   
   In Home Designer Pro, select CAD> Boxes> Rectangular Polyline .
   
   
   
3. Drag a rectangular marquee around the entire structure.
   
   
   
4. Use the Add Break  and Change Line/Arc  edit tools to reshape the polyline around the main structure.
   
   
   
   
   • To use the Add Break  edit tool, click the edge that you want to break into two segments. Next, click the edit button, then click the edge to create a new corner edit handle at that location and two separate edges on either side of that handle.
     
     If you click and drag one of the edit handles on either side of the partial break, the edge moves at a right angle to itself and another edge forms, connecting the moved edge with the one on the other side that does not move.
     
     

     You can remove an edge from a polyline-based object by clicking and dragging an edit handle until it snaps to an adjacent corner handle.

     
     
   • Select an individual line-based or arc-based object or a segment of a polyline-based object and click the Change Line/Arc  edit button to convert the selected segment from a line to an arc or vice versa.
   
   
   
5. With the polyline selected, click on the Open Object  edit button.
   
   
   
6. On the Polyline panel of the Polyline Specification dialog that opens, take note of the Area listed.
   
   
   
   
   
7. (Optional) Select CAD> Text> Rich Text  from the menu, then click once in your drawing area to open the Rich Text Specification dialog.
   
   
   • In the Text field, type the Area value of the polyline noted above, as well as any other additional information that you would like to include here.
     
     

     Keep in mind that any changes made to your floor plan after adding this text box will need to have the area recalculated, and this text manually updated. It will not update automatically.

     
     
   • Click OK to close the dialog and create a text object.
