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

Aim - To create 3D model of furniture

Procedure -

• open Autocad file
• Set the unit as impherical
• Unit set to engineering with precision 0'0"
• Set lim 0,0 and 100,100
• Z enter,A enter for zoom all
• From setting switch to 3D modelling
• Set to top view 2D wireframe
• Draw a rectangle of 3'x3' in xy plane
• Explode the rectangle
• Offet three sides at a distance of 2"
• Enter boundary command and select offset line and make a region
• Similarly repeat the same for other two sides and whole rectangle
• Go to default view by clicking home icon
• select excrude from ribbon and select all region
• Excrude at a height in z axis 2'6"
• Select substract command and select rectangle and then enter
• Select smaller rectangle and enter
• Select union command and select all object enter
• Use linear dimension and measure by switching UCS

Aim - Create 3D model of Isolated footing

Procedure -

• Set the view to top and 2D wireframe
• Draw a rectangle of each side 2"
• Select offset command and select rectangle and enter the distance as 1'
• Move the default view
• Enter move command select 1'x1' rectangle and move at a distance of 3'
• Select loft command,select two rectangle and enter
• Now excrude the rectangle of size 2'x2' with height 6"

Aim - Createb 3D view of AASTHO type Girder

procedure -

• Set the view to top and wireframe
• Draw a set of rectangle of dimension 10'x6",10'x1'4",10'x1'6",10'x1'
• Now align the rectangle in bigger recatngle using geometric center
• Set the view to SW isometric
• Excrude rectangle upto given height as 10'6" to 1'6"
• Follow the same of remaining
• Align the rectangle upto certain height using move command,move the rectangle 10'x6" at a height of 0,0,1'
• Now tamper last second rectangle by selecting width face,specifying base point and axis enter angle as 15
• Similarly for second rectangle enter angle as 45
• use union command to join the excruded section

Aim - create 3d model of Drop column with panel

Procedure -

• Select the top view with wireframe
• draw a circle of 1'6"
• Excrude the circle at height 10'
• Move back to top view and draw a rectangle of size 3'6" x 3'6"
• Place the rectangle on circle using onsnap or enter distance s 0,0,10
• Excrude the rectangle at height of 1'
• Select tamper command from solidedit tool and select the face
• Specify the base point and enter the angle as 45
• repeat the same on other side or use loop command in tamper
• Back to top view and draw a recatngle of side 4'6"x4'6"
• Move back to isometric view and excrude at height 6"
• Place the rectangle of top 3'6" recatngle using UCS icon or distance command
• USe union to make object one

Aim - Create 3D model of Wall

Procedure -

• Set the top view and wireframe
• Draw a recatngle of size 10'9"
• Now explode the rectangle
• Offset the width on both side at a distance of 3.5'
• Enter boundary command and selct point and region
• Set the view to default isometric
• Excrude the corner region upto height 12'6"
• Now move the door rectangle to height 0,0,7'
• Now excrude the moved rectangle upto 12.5'
• Set the view to front and draw a triangle of sides 5.5'and base 10'
• Make triangle as region using boundary command
• Excrude the triangle at a distance 9" towards y axis
• Use presspull to reduce the rectangle wall
• Use union command to join all excruded wall
