2.3.3 - First floor - interior walls

The final layout of the exterior and interior walls of the First floor will be like the one you see in the sketch of Fig.2.3.3.1. You will follow the dimensions that you see in this sketch to design the interior walls.

The interior walls will have as width 0.15, (this value is in units, in this project we use the meter as one unit, the value 0.15, means 0.15 meters or 15 cm), as Base Height 3.00, as elevation 0.00.

You will draw the walls  and (BD), (JC), and (HG).
To do this:

  • Open, with AutoCAD Architecture, the drawing h21190_firstFloor_exterWalls.dwg that you created in the previous lesson 2.3.2.
  • Draw three Construct lines, one that passes on the inside of the wall (Ah), one that passes on the inside of the wall (A1g), and one that passes on the inside of the wall (ah) (Fig.2.3.3.2).
    Construction lines (also known as xlines) are temporary linework entities that can be used as references when creating and positioning other objects or linework. Construction lines are either circles or straight lines that extend to infinity in both directions. They do not change the total area of the drawing and have no effect on zooming or viewports.
    In most cases, you can to draw construction lines based on segments of existing objects, but you can also draw them by specifying any two points in the drawing area, without regard to existing objects or linework.

To use Construction Lines tool:

  1. Click Home tab ► Draw panel  ► Line drop-down icon (hover on ►)  ► select Construction Line tool

    Draw construction lines on the inside of the exterior walls, as shown in  Fig.2.3.3.2 :
  2. Select (MB1) as linework to create xline (MB1), set as offset = 0.00, and draw construction line (MB1).
  3. Select (ME) as linework to create xline (ME), set as offset = 0.00, and draw construction line (ME).
  4. Select (EF) as linework to create xline through(EF), set as offset = 0.00, and draw construction line (EF).
  5. Select (AF) as linework to create xline through(AF), set as offset = 0.00, and draw construction line (AF), and press Esc.

    Draw construction lines for the internal walls (B1D), (JC), and (HG), (Fig.2.3.3.2) :
  6. Offset Construct line (MB1), define as distance 3.60, and select a point near the line (JC) to set the side to be executed the offset command, and define construction line (JC).
  7. Offset Construct line (AF), define as distance 3.35, (is the sum of individual 3.20 +0.15), and select a point near the line (B1D) to set the side to be executed the offset command, and define construction line (B1D).
  8. Offset Construct line (EF), define as distance 1.80, (is the sum of individual 0.15 + 1.65), and select a point near the line (HG) to set the side to be executed the offset command, and define construction line (HG).

Type Text

 On Ribbon, set text style Standard as current, set layer "A-Notes" as Current, select on Ribbon the Single Line text tool, (hover on) and type the letters B, B1, C, H, D, M, G, E, J, F, m, at the section of construction lines, as shown in Fig.2.3.3.2.

Draw the Walls

Before you continue, create a new layer to use for the interior walls, by name A-Wall-Inter, set as color: 113, and make it current (The reason for creating this new layer with color = 113, is to distinguish visually the inner from the exterior walls).

  • In Design Tool palette, find the tool Wall (Fig.2.3.3.3) - this tool 'Wall' uses the wall style standard -, click on it to open the panel Properties - Wall (Fig. 2.3.3.4).
  • Fig.2.3.3.3 - Tool Palette - Wall
    aca18 toolPalet designWall t214300
  • In properties palette (Fig.2.3.3.4),and in category General, you will notice that the Style is Standard. Using the standard style wall, this means that the wall you plan has only one element and consists of only two parallel lines, one right and one left.
  • In Properties palette scroll to category Dimensions and set Thickness to 0.15 and Base Height to 3.00.
    These are the dimensions of the real wall that you will use later to replace the 'standard' wall that you used to design the interior walls.
  • In category Location set Elevation = 0.00, is the level where the walls will be placed.
  • Scroll down on the left side of the panel to find the field Justify. Press the right field, click the arrow that appears on the right, and select right (Fig. 2.3.3.4).
    The justification of the wall determines the side of the wall that we will use as a guide for its placement.

To draw the wall (BD), (JC), and (HG), as shown in Fig.2.3.3.1:

With tool Wall selected, aca18 icon buildWall 6028  draw the walls (AA1) and (BD) in the direction from A to A1, and from B to point D.

  • At the prompt: Start point or […]: select point B1,
  • At the prompt : End point or […]: select point D, and press ENTER.
  • At the prompt: Start point or […]: select point J,
  • At the prompt : End point or […]: select point C, and press ENTER.
  • At the prompt: Start point or […]: select point H,
  • At the prompt : End point or […]: select point G, and press ENTER.
    The walls (B1D), (JC), and (HG) were designed.

You have created the interior walls (B1D), (JC), and (HG) of the basement plan, which have thickness 0.15 m, Base height 3.00 m, Elevation 0.00 m, and you have set all the interior walls to layer 'A-Wall-Inter' .

If you select any of the interior walls (B1D), (JC), and (HG), their properties will appear in the Properties palette.

  • In Properties palette, you will notice that the wall Layer is A-Wall, it is the default layer for the style Standard, change the layer of all interior walls to A-Wall-Inter. Notice also that, the wall style is Standard, Thickness is set to 0.15, Base Height to 3.00, and Justify is set to Right.
  • In category Location, the Elevation  is set to 0.00.

The plan of the basement, after the design of the exterior and interior walls, will be as shown in Fig.2.3.3.2 (without dimensions).

Draw the Dimensions

Draw the interior Dimensions on the First floor drawing, as shown in Fig.2.3.3.1. At first you have to create a new layer under the name "A-Dim-Details", set it's color to 86, and set it as the Current Layer, alternatively to the process you followed at the previous paragraph you will follow another way to set the current layer.

    • Set layer A-Dim as the current Layer. To do this:
    • Click Home tab > Layers panel > click on the Layer tab (hover on) aca18 ribbon layerTab 20026 and a drop-down menu will open. This menu provides a choice of layer settings defined in the drawing to make current. Select the layer A-Dim, to make it current.

    • To draw the dimension between walls (ab) and (AB),

  • Make sure that Dimension Style Standard as the current dimension style,
    to do this Click Annotate tab > Dimensions panel > click on icon aca18 annotate dimStyle 24> on the Dimension Style Manager dialog box, select style Standard > click on the tab Set Current > select on the top tab 'Text' to open the corresponding dialog box, as shown in Fig.2.1.1.7. Here set the text height= 0.15, go back, select tab 'Symbols and Arrows' tab and set Arrow Size= 0.18, go back, select tab 'Primary Units' tab and set Precision= 0.000, go back, select tab 'Fit' tab and on category 'scale for dimension features', set Use overall scale of = 1.000.
  • Click Annotate tab > Dimensions panel > click on the Linear Dimension icon (hover on) aca18 iconAnnotatIon linearDim 26. This icon  invokes a tool for adding a dimension to the selected object. Before start drawing dimensions select on the Dimensions panel, 'Standard' as the default Dimension Style.
  • To Specify on the screen the first point of dimension, select the uper-right point of the wall (ab) close to point (a) of the wall (Fig.2.2.3.1).
  • To Specify the second point (A) of dimension, select the uper-left point (A) of the wall (AB).
  • To Specify the Dimension location line, select with your mouse a point downward of wall (ah).
  • The same way, create all the dimensions, as shown in Fig.2.3.3.1.

The plan of the basement, after the design of the exterior and interior walls, will be as shown in Fig.2.3.3.0.

Save this drawing under the name h21190_groundFloorWalls in the folder customDwg\groundFloor you have created, the full path will be: C:\ACA\myProjects\house21_190\customDwg\groundFloor\h21190_basemWalls.

3D Isometric View

To have a 3D isometric view of your project, on the View Cube tool, at the upper right corner of your screen, click on the corner WS of the Cube.

You can apply a Conceptual style view in your drawing to have a more artistic view:

  • To set the Visual Style of the drawing, on Ribbon > click on View tab > click the arrow on Visual panel (hover on ►), the drop-down which will open provides a choice of visual styles defined in drawing to make current (for the moment the current visual style is the 2D Wireframe) > select Conceptual, to make this visual style current.
    The result is shown in Figure 2.3.3.5.
