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

Q 1). Create a 3D Furniture element as shown in the Figure. Assume dimensions Which are missing.

Aim:- To create a 3D Furniture element as shown in the Figure.

Procedure:-

1. open a new AutoCAD file> 3D Modeling.
2. let's change the units for that on the command prompt type units>engineering>inches>0"-0".
3. set the limits, on command prompt type 'Limax' > 100',100'
4. 
5. on the command prompt type 'Limits' > 0,0
6. 
7. now, by using the L command give the lines of dimensions 2',3' & 2;-6".
8. after that extrude the rectangle by using Extrude command.
9. now draw the inner rectangle by using the 'rec' command.
10. To subtract the inner object use the subtract command.

Result:-

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

Aim:- To Create the 3D model of an Isolated footing.

Procedure:-

1. open a new AutoCAD file> 3D Modeling
2. let's change the units for that on the command prompt type units>engineering>inches>0"-0".
3. set the limits, on the command prompt type 'Limax' > 100',100'
4. on the command prompt type 'Limits' > 0,0
5. by using the line command draw desired lines of dimensions 6",3',2'
6. draw a rectangle of size 1' x 1'.
7. by using the 3Dface command to give the surface.

Result:-

Q 3). Create the 3D view of the AASTHO Type Girder.

Aim:- To create the 3D view of the AASTHO-type girder in AUTOCAD 3D.

Procedure:-

• open a new AutoCAD file> 3D Modeling
• let's change the units for that on the command prompt type units>engineering>inches>0"-0".
• set the limits, on the command prompt type 'Limax' > 100',100'
• on the command prompt type 'Limits' > 0,0
• by using the L command to draw the desired lines at the SW view.
• again using the line command draw the line of distance 1'-6",6", 1'-6" and 1"
• now, extrude the object by using extrude command.

Result:-

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

Aim:- To create a 3D model of a drop column with the panel.

Procedure:-

• open a new AutoCAD file> 3D Modeling
• let's change the units for that on the command prompt type units>engineering>inches>0"-0".
• set the limits, on the command prompt type 'Limax' > 100',100'
• on the command prompt type 'Limits' > 0,0.
• by line command draw the desired lines of distance 10', 1'-6",6",3'-6",4'-6".
• draw a circle by using command C.
• extrude the object by using extrude command.
• with 3dorbit the 3D view is obtained.

Result:-

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

Aim:- To create the 3d model of a wall using Autocad.

Procedure:-

1. open a new AutoCAD file> 3D Modeling
2. let's change the units for that on the command prompt type units>engineering>inches>0"-0".
3. set the limits, on the command prompt type 'Limax' > 100',100'
4. on the command prompt type 'Limits' > 0,0.
5. open drafting settings (ds) off "snap on" and off "grid on".
6. select on isometric snap & turn on ortho mode (f8).
7. in the command prompt type line
8. specify the point or select a point
9. press f5 for isodraft to get the line in desired diection, keeping the isodraft in left direction one side of the wall is drawn.
10. changing the isodraft in the other direction thr next side of the wall is drawn.
11. in the command prompt type the required distance.

Result:-
