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

AIM:  Create a 3D Furniture element as shown in the Figure. 

Introduction: using auto cad 3D modelling draw a 3D furnture element by using polysolid command and dimension command for dimensioning the object 

Procedure :

Step 1) open auto cad (2019) with imperical 

 set unit as engineering (feet,inches) 

and go for 3D modelling 

step2) go to solid command 

select polysolid option 

and give width as 2" and height as 2'6" 

and draw a line in 2D wireframe 

first start origine point draw a line of 3'X3'X3' and also at top make a rectangle of 3'X3' 

with 2" line width 

and then go for hidden option so only front side is visble and adjust by using 3Dorbit 

then give dimension by setting UCS and using DIMalined command 

Result: we create a furniture by using polysolid command with 2" thick and give dimensions to object 

2) AIM: Create the 3d Model of an Isolated footing as shown in Figure.

Introduction : draw Isolated footing in 3d modeling using auto cad 3d

Procedure: 

Step 1) open auto cad (2019) with imperical 

 set unit as engineering (feet,inches) 

and go for 3D modelling 

step2) 

go for top view and draw a rectangle

by choosing rectangle command of size @ 1'X1'

then choose OFFSET command and offset the rectangle through 

at aprox double distance also draw same rectangle over it 

then give height to smaller rectangle to Z axis at distance of 2'

and also height of biger one rectangle with Z axis at a distance of -6" 

and joint the line using loft command

then using dimalined command give the dimension to object

result: we draw isolated footing using loft and rectangular command and dimension is given to object 

3) AIM: Create the 3D view of the AASTHO Type Girder.

Introduction: draw a AASTHO type Girder using rotate3D command and extrude command 

Procedure: 

Step 1) open auto cad (2019) with imperical 

 set unit as engineering (feet,inches) 

and go for 3D modelling 

step2) 

go for TOP view and draw a I section 

draw a rectangle of size @1',6"

then draw bottom rectangle using rectangl command 

bottom retangle from the bottom center of the top rectangle with size 6", 1'6" 

and after that below 6" draw a rectangle with size 1'6", 6"

and fillet with 2" radies at bottom and connect all rectangle with help of line command by ortho offing 

and trim the extra line using TRIM command 

step3) make extrude to object 

after completing top view 

region the object using REGION command 

and rotate it by 3D rotate command with 90 degre angle with x axis 

and EXTRUDE the object with 10' at z axis 

result: we draw the AASTHO using 3D rotate and EXTURE command 

4) AIM: Create a 3d Model of a  drop column with panel as shown in section and isometric view.

INTRODUCTION: using auto cad 2019 draw 3D modeling of column with panel .

Procedure 

Step 1) open auto cad (2019) with imperical 

 set unit as engineering (feet,inches) 

and go for 3D modelling 

Step 2) go for top view 

and select circle command and draw circle of 1'9" dia 

with 10' extrude at bottom side with - z axis,

then secont rectangle with -1'6" at z axis of a size of 3'6" each 

and by using loft command joint the both rectangle 

and drwa a other rectangle of size 4'5" over that rectangle and joint line using loft command 

and give dimension using dimlined and oriented with front size 

and use hidden view from left corner of screen 

step3) 

hidden the object and rotate orbit by using 3D orbit

and shaded it for solid visibility

result: we draw the 3d model of a drop column with panel using loft and rectangle command

5) AIM: Create the 3d model of a wall as shown in Figure. Consider wall thickness as 9”.

Intoduction: draw a door opening with wall using auto cad 3D 

Procedure: 

Step 1) open auto cad (2019) with imperical 

 set unit as engineering (feet,inches) 

and go for 3D modelling 

step2) 

take line command 

make view as isomatric from top left corner 

take a origine then draw a verticle line with 12'6" distance 

then draw horizontal line of 10' length then again bottom with 12'6" and close the it and make rectangle 

then gives 9" wall thickness by using line command 

then go for middle of bottom line and make door of size 3'X7' with 9" wall thickness 

then use CHAMFER command and chamfer the object with top middle to 10' from bottom 

and trim extra lines using TRIM command 

OR we can also draw this object by using POLYSOLID command with 9" width and 12'6" height 

and by using subtract command we can make a opening 

and after making object we use dimlined command for dimensioning object with text height is 3 unit 

and finally EXTRUDE the object with 9" by using EXTRUDE command for making solid object 

Result: we draw 3D model of wall using 3D command using polysolid command or also make it by line command with chmafer and dimension command
