QUESTION

I need to manually modify deck framing that Chief Architect created in my plan. What are my options?

BBQ, patio, and a deck with stairs going down to the backyard.


ANSWER

When a room is defined as a Deck in Chief Architect, framing is generated automatically. This is a fast way to generate posts, beams, joists and planking, but sometimes manual modifications may still need to be made.

In this article, we will cover the following topics:

Note: Chief Architect is not an engineering program and will not calculate loads or other important structural considerations. Always have your designs approved by a licensed engineer before building.


To create the initial structure

  1. Select File> New Plan to open a new, blank plan.


  2. Select Build> Wall> Straight Exterior Wall , then draw exterior walls forming a perimeter, making sure to create a fully enclosed space.


  3. Select Terrain> Create Terrain Perimeter to create a flat terrain pad.


  4. Next, navigate to Terrain> Terrain Specification from the menu.


  5. On the General panel of the Terrain Specification dialog that displays, remove the check from the Automatic box beside Subfloor Height Above Terrain, change the Subfloor Height Above Terrain value, then click OK.


  6. Select Build> Floor > Build Foundation to open the Build Foundation dialog.


  7. On the Foundation panel, select Walls with Footings as the Foundation Type, specify the Minimum Height under the Stem Wall section, then click OK.

  8. Go Up One Floor  to Floor 1, select Build> Railing and Deck> Straight Deck Railing  and draw railings to enclose one or more Deck rooms attached to the structure.

    Note: If a Deck is drawn on Floor 1 and a foundation is present, the deck framing will be drawn on Floor 0. If no Floor 0 is present, the deck framing will be created on Floor 1.

  9. Using the Select Objects  tool, click in an empty space in the Deck room to select it, then click the Open Object  edit button.

    Selected the room area to make it a deck


  10. On the Deck panel of the Room Specification dialog that opens, uncheck Automatically regenerate deck framing, then click OK.

    Turning off Automatically regenerate deck framing in the Room Specification dialog

    Note: Grayed out options on this panel indicate that the Room Type is set to something other than a Deck. For framing to generate, define the room as a Deck, click OK, then open the room back up to specification to disable the setting mentioned in this step.  


To adjust deck planks

  1. With the CAD> Lines> Draw Line  tool, create a line at the corner where the miter should be.

    In X12 and prior versions, framing ends will be square even if trimmed on an angle.


  2. Select the CAD line and click the Trim Object(s)  edit button.


  3. Click and drag a temporary line, or fence, that runs through the deck planks on one side of the miter CAD line.

    In X14 and newer versions, the deck planks will highlight for the portion that will be kept after trimming.

  4. When you release the mouse button, the ends of the planks will be trimmed back to the inside edge of the CAD line.

  5. Repeat these steps for any other areas where the planks need to be mitered, and use the edit handles to extend the length of the planks as necessary.


  6. When you are finished, you can select 3D> Create Perspective View> Full Camera  to see the results.


To adjust deck joists

  1. Select one or multiple joists with Select Objects Select Objects tool icon.

    Hold down the Shift key on your keyboard and click on another framing member to add it to the selection set. For more information on group selecting objects, please see the Related Articles section below.

  3. With the joists still selected, use the edit handles to change their location.


  4. Click on Open Object Open Object tool icon to adjust the Bottom Height, Depth, WidthRole*, and Type.

    *Only available in X14 and newer program versions.

  5. Select the beam and click the Trim Object(s)  edit button. These steps also work with a CAD line.


  6. Click and drag a temporary line, or fence, that runs through the joists where they extend into the beam.

    In X14 and newer versions, the deck joists will highlight for the portion that will be kept after trimming.

To adjust deck beams

  1. Using the Select Objects tool, click on a beam that runs under the Deck room.


  2. Click the Delete edit button or press the Delete key on your keyboard to remove this beam.
