Floor Plan Creation (AutoCAD – Simple Steps)

1. Set Units

  • Command: UN → Enter

  • Units → Architectural

  • Precision → 1/4

  • Insertion scale → Inches

2. Draw Outer Rectangle (House Boundary)

  • Command: RECTANGLE

  • Click anywhere, then type: @50',31' → Enter

3. Draw Interior Walls (using Line tool)

  • Command: LINE

  • Track from corners (ensure Object Snap → Extension is ON).

  • Example steps:

    • Up: 15'

    • Right: 12'

    • Down (etc.) … until boundaries complete.

4. Add Wall Thickness (Offset)

  • Command: OFFSET

  • For exterior walls: 10" offset outward.

  • For interior walls: 6" offset both directions.

5. Clean Geometry

  • Command: TRIM

  • Remove overlapping/extra parts at intersections.

6. Create Layers

  • Open Layer Properties

  • Add layers:

    • Door → Magenta

    • Window → Orange (or Blue)

    • Blocks → Cyan

    • Hatches → Green

    • Text → Yellow

    • Dimension → Pink

7. Make Door Block

  • Switch to Door layer.

  • Draw rectangle: @3",3'

  • Small rectangle: @3",6" → move to edge.

  • Add arc (swing).

  • Copy rectangle to other side.

  • Mirror for variation.

8. Make Window Blocks

Window 1:

  • Rectangle: @5',6"

  • Offset: 1" → up/down

  • Copy line to midpoint

  • Trim middle

Window 2:

  • Rectangle: @6',10"

  • Explode

  • Offset: 2" both sides

  • Copy line to midpoint

  • Trim

9. Convert to Blocks

  • Command: BLOCK

  • Name blocks:

    • Door1, Door2, Window1, Window2

  • Pick point → select objects → OK

Floor Plan – Part 2 (Adding Blocks, Hatches, Text)

1. Insert Door Blocks

  • Use Copy tool → place door block at wall.

  • Use Mirror to flip as needed.

  • Use Rotate to align with wall.

  • Delete extra/unneeded copies.

2. Insert Window Blocks

  • Copy window block → rotate to correct angle.

  • Place inside walls (consider 10" wall thickness).

  • Copy/move to multiple wall positions.

  • Erase original unused blocks.

3. Clean Geometry

  • Use Trim to remove overlapping lines after inserting doors/windows.

4. Save Drawing

  • Save file → name it floorplan.dwg (or similar).

5. Use Design Center for Interior Blocks

  • Open with Ctrl+2 (or command: ADCENTER).

  • Navigate to: en-us → Design Center.

  • Common categories:

    • House Designer → Blocks: bathtub, toilet, sink.

    • Home Space Planner → Blocks: bed, dining set, lamp, plant, sofa.

    • Kitchens → Blocks: oven, refrigerator, double sink.

  • Drag & drop blocks into drawing.

  • Change to Blocks layer (if wrong color).

6. Place Furniture Blocks

  • Bedroom: bed + lamps + table.

  • Toilet: toilet, bathtub, sink (rotate/move into position).

  • Dining: dining set (rotate 90° if needed).

  • Living Room: sofa, table (with fillet corners), TV, plants.

  • Kitchen: sink, oven, fridge, slab made with Line + Trim.

7. Add Hatches (Wall Thickness)

  • Switch to Hatch layer.

  • Command: HATCH → choose Solid pattern.

  • Click inside wall cavities (each closed area).

  • Close hatch creation.

8. Add Text (Room Labels)

  • Change Text Style:

    • Command: STYLE → Font: simplex.shx

    • Height: leave blank (set when placing).

  • Layer: Text.

  • Command: MTEXT → Draw text box → type room name.

  • Set text height = 1'.

  • Place and copy text to each room.

  • Edit each copy to match room:

    • Bedroom 1, Bedroom 2, Toilet, Drawing Room, Dining, Kitchen, Air Vent, etc.

  • Rotate/move text if needed for proper orientation.

✅ By this point, drawing includes doors, windows, furniture blocks, hatches, and text labels. Next step (in Part 3): add dimensions + plotting.

Part 3 – Simplified Steps (Point-Form)

1. Add Dimensions

  • Switch to the Dimension layer (pink).

  • Use the DIMLINEAR command for straight measurements.

  • Apply dimensions to key elements like wall lengths, room widths, etc.

  • Adjust arrow size, text placement, or style if needed.

2. Set Up Layout and Viewports (Paper Space)

  • Switch to a Layout tab (e.g., Layout1).

  • Insert a Viewport (command: MV or MVIEW) to display your model space drawing.

  • Adjust viewport scale to fit your floor plan (e.g., ¼″ = 1′-0″ or similar architectural scale).

  • Lock the viewport to avoid accidental zoom/move inside it.

3. Add Title Block & Annotations

  • Insert or draw a title block frame in paper space (with project details, scale, sheet number).

  • Add annotation text for title, scale, author, date, etc., using Text layer formatting.

4. Plot/Print Settings

  • Open Plot dialog (click Plot icon or PLOT command).

  • Select your printer/plotter or choose "DWG to PDF" for digital output.

  • Choose correct paper size (e.g., A3, A2 depending on layout).

  • Set plot scale to 1:1 (paper space handles scale via viewport).

  • Check plot window: ensure layout includes all content.

  • Preview → print or save as PDF.

Why These Steps Matter

This final phase ties all previous work—walls, blocks, hatches, text—into a presentable floor plan, ready for actual use or sharing.

✅ Adding Dimensions

  1. Open Dimension Style Manager

    • Annotate → Dimensions → Dimension Style Manager

    • Copy an existing style (e.g., ISO-25 → New → Name it “DIM”).

  2. Modify the Style

    • Symbols & Arrows → set arrowhead to Architectural Tick.

    • Text → text placement → Centered.

    • Primary Units → Unit Format → Architectural.

    • Fit → Adjust overall scale (e.g., 5) if dimensions look too small.

  3. Place Dimensions

    • Switch to DIM layer.

    • Use Linear Dimension (DIMLINEAR) → click two points → place dimension.

    • Hide hatches temporarily if they block snap points (Lightbulb icon → HATCH off).

    • Add only essential dimensions (room sizes, wall lengths, openings, etc.) – avoid redundancy.

  4. Add Notes

    • Use Text tool → e.g.,

      Exterior wall thickness = 10”
Interior wall thickness = 6”

    • Place text on the TEXT layer (not DIM).

✅ Preparing the Layout (Paper Space)

  1. Switch to Layout tab (Layout1).

  2. Delete default viewport (if any).

  3. Page Setup

    • Right-click Layout → Page Setup Manager → Modify.

    • Printer: DWG to PDF.

    • Paper size: ISO A3 (landscape).

    • Plot area: Layout.

    • Save & Close.

✅ Creating the Viewport

  1. Layout tab → Rectangular Viewport → draw inside dotted plot margin.

  2. Double-click inside viewport → set scale (e.g., 1:100, 1/4"=1'-0").

  3. Lock viewport to prevent accidental zoom/pan.

✅ Plotting (Printing)

  1. Plot command (PLOT)

    • If you want colored output → Plot style = None.

    • If you want black & white → Plot style = Monochrome.ctb.

  2. Preview → Save as PDF.

    • e.g., floorplan_color.pdf or floorplan_bw.pdf.

👉 At this point you have a dimensioned + properly scaled floor plan in PDF, both in color and monochrome.
