Creating various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad

1. To create a 3D Furniture element as shown in the Figure.

Introduction : For creating a 3D Furniture element follow the below steps Command to command.

Step 1: Starting with making lines by specifying distance on further directions so, give the

Command: L

LINE

Specify first point:

Specify next point or [Undo]: 2'

Specify next point or [Undo]: 3'

Specify next point or [Close/Undo]: 2'

Specify next point or [Close/Undo]: 2"

Specify next point or [Close/Undo]: 1'10"

Specify next point or [Close/Undo]: 2'8"

Specify next point or [Close/Undo]: 1'10"

Specify next point or [Close/Undo]: *Cancel*

Step 2: Extruding the object above at a distance of 2’6” so by,

Command: EXTRUDE

Specify height of extrusion or [Direction/Path/Taper angle/Expression]: 2'6"

Step 3: Drawing a rectangle above by Joining the two points so by command

RECTANG

Specify first corner point

Specify other corner point

Step 4: By command Extrude Extrude below the 2” to acquire the given figure

Command: EXTRUDE

Specify height of extrusion : 2”

2. Aim: To create the 3d Model of an Isolated footing as shown in Figure.

Introduction: For creating a 3D Furniture element follow the below steps Command to command.

Step 1: Draw a box by BOX command of length 2’X2’ and height of 6”

Step 2: Draw a rectangle by RECT command at center of the box to of length and width 1’X1’

Step 3: Move it on the z axis above 2’ height by Command MOVE

Step 5: By Line command LINE join the corner of the boxes to the corners of the rectangle to draw as same as figure.

3. Aim: To create the 3D view of the AASTHO Type Girder

Introduction: For creating a 3D Furniture element follow the below steps Command to command.

Command: L

LINE

Specify first point:

Specify next point or [Undo]: 1’4”

From each corner Draw a line of 1” at an angle of 135 and mirror it to make same as other side

At next

Command: L

LINE

Draw a line

Specify next point or [Undo]: 1’6”

Ortho on

Draw a line of  height 6” ( straight line on both side facing above)

Ortho off

Draw a line at angle of 45 and distance is 6” on both sides and height is also 6”

Ortho on

Draw a line of 1’6” ( straight line on both side)

From each corner Draw a line of 1” at an angle of 135 and mirror it to make same as other side

Draw a line of height 6” ( straight line on both side facing above)

Close the line , figure

Command Extrude

Extrude the figure we have made at 10’

4. To create a 3d Model of a drop column with panel as shown in section and isometric view.

Introduction: First we made a 2d model and then after draw a 3d isometric view

Step 1: Draw a rectangle of LXB (10’X1’6”)

Command RECTANGLE

Step 2: Draw a line of 1” height at angle of 135 and mirror it to draw as same at other side

Command used LINE, MIRROR

Step 3: Join the both corners by Using LINE command

Step 4: Draw a line of 1’ from both the corners

Step 5: Draw a line of 6” facing upwards and join both of the lines to acquire the 2d figure

3D figure

Step 1: Draw a box of length 4’6”X4’6” and height 6” by using BOX command  

Step 2: On the geometric center and draw a line from the center 10’ below

Step 3: Command EXTRUDE

Extruding by defining a path i.e line drawn to acquire the figure

 

5. To create the 3d model of a wall as shown in Figure

Introduction: Making a 3d model of a wall and  Considering  wall thickness as 9”.

Step 1: Draw a line of 3’6” by LINE command

Command: L

LINE

Specify first point:

Specify next point or [Undo]: 3’6” (Right)

Specify next point or [Undo]: 7’ (Above)

Specify next point or [Close/Undo]: 3’ (Right)

Specify next point or [Close/Undo]: 7’ (Below)

Specify next point or [Close/Undo]: 3’6” (Right)

Specify next point or [Close/Undo]: 10’ (Above)

Specify next point or [Close/Undo]: 10’ above from the first point

Specify next point or [Close/Undo]: *Cancel*

Step 2: Draw a taper of total height 12’6”

Step 3 : Draw the wall thickness by using LINE Command
