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

CHALLENGE 11-

INTRODUCTION- COMMANDS USEDFOR DRAWING THE 3D OBJECTS ARE AS FOLLOWS.

• Extrude- Location: Draw > Modeling > Extrude

This AutoCAD 3D Extrude command allows the user to create a 3D object by extruding a 2D face along a line or path.

• Sweep- Location: Draw > Modeling > Sweep

This command helps the user to extrude the 2D objects without the 2D face being orthogonal to the beginning of the path.

• Union- Location: Modify > Solids Editing > Union

This AutoCAD 3D command allows the user to combine two objects converting into one single object.

• Subtract- Location: Modify > Solids Editing > Subtract

This command is opposite to the union command; this command works when there is a common area in both the objects. Then this command subtracts the object A from the object B.

• Intersect- Location: Modify > Solid Editing > Intersect

With this AutoCAD 3D command the user is left with the area that is common to both the objects.

• Revolve- Location: Draw > Modeling > Revolve

This AutoCAD 3D command creates a 3D solid by revolving a 2D object around an axis.

PROBLEM-1

AIM- TO DRAW A 3D FURNITURE ELEMENT.

STEPS.

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as engineering and select precision as 0’-0’’.
• Now enter Dim style in command box and modify the settings and select primary units as engineering and give precision as 0’-0’’.
• Line command is used to draw the 3D object.
• Command line draw the line 2’6’’ in Z direction.
• Line of 3’ in the the Y direction.
• Line 2’6’’ in the negative Z direction.
• Offset of 2’’ as the thickness of the 3D object.
• Assume the width of the object as 2’3’’.
• Move the UCS usind the command 3D face and place in the desired manner to very side to give the dimension using the Dim linear command.
• Use face command and select the particular face and then give the dimensions using the dim linear command.

PROBLEM-2

AIM- TO CREATE A 3D MODEL OF ISOLATED FOOTING.

STEPS-

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as engineering and select precision as 0’-0’’.
• Now enter Dim style in command box and modify the settings and select primary units as engineering and give precision as 0’-0’’.
• Draw a rectangle of 1’x 1’ in the 3d view.
• Give an offset of 1’ to the rectangle in the outside of the rectangle.
• Extrude the bigger rectangle to the eight of 6’’.
• Move the inner rectangle at the height of 2’6’’.
• Join all the corner points.
• Use the command 3d orbit to move the object in the degred mannerand join all the corner points.

PROBLEM-3

AIM- TO CREATE A 3D VIEW OF ASTO TYPE GIRDER.

STEPS-

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as engineering and select precision as 0’-0’’.
• Now enter Dim style in command box and modify the settings and select primary units as engineering and give precision as 0’-0’’.
• Create the front view of the ashto type girder as shown in the 3d view using the line command.
• Extrude the object in the 3d view.
• Use the 3D orbit command and move the object as desired

PROBLEM-4

AIM- TO CREATE A 3D MODEL OF DROP COLUMN.

STEPS-

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as engineering and select precision as 0’-0’’.
• Draw a circle in the 3D mode of 1’6’’.
• Extrude the circle by using the extrude command in the ribbon 10’ long.
• Use the command cone and draw the cone of 3’6’’ and bottom side of 1’ 6’’ with the height of 1’.
• Again, draw the rectangle of 4’ 6’’ and extrude it with thickness of 6’’.
• By using the command 3D move the objects and place it on one another as desired in the 3D figure.
• Use the 3D orbit command to align the figure.
• Use dim linear command to give the dimension.

PROBLEM 5-

AIM- TO CREATE A 3D MODEL OF THE GABLE WALL.

STEPS.

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as engineering and select precision as 0’-0’’.
• Now enter Dim style in command box and modify the settings and select primary units as engineering and give precision as 0’-0’’.
• Using line command to draw the wall.
• Draw a line of 10’ in the X direction.
• Specify the center of the line of 1’
• Draw a line of 1’-5’’ in both the direction with the height of 7’ to draw the door of the wall.
• The thickness of the wall is considered as 9’’.
• Draw the top of the wall on the distance of 12’-6’’ from the bottom. Offset 9’’ to draw the roof of the wall.
• Use dim linear command to give the dimensions.
• Move the UCS using the command 3 point from the ribbon and give the dimensions.
