- Creating various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad.
1. Create a 3D Furniture element as shown in the Figure. Assume dimensions which are missing.
Procedure -
Type UN and press enter
Under Drawing Units, select Archetectural (feet and inches)
Now the lower limit is set to 0', 0' and upper limit to 50', 50'
Type Z enter to zoom and A enter to all.
Now in settings selecting 3D Modelling and visual style control to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour .
Type L and press enter
Specify the first point as anywhere in the drawing.
Line specify next point: @0,0,2'-6" and press enter.
Line specify next point: @0,3',0 and press enter.
Line specify next point: @0,0,-2'-6" and press enter.
Line specify next point: @0,-2",0 and press enter.
Line specify next point: @0,0,2'-4" and press enter.
Line specify next point: @0,-3',0 and press enter.
Line specify next point: @0,0,-2'-4", and press enter.
Line specify next point: @0,-2",0 and press enter
Draw a rectangle at top of dimensions 2'-2" x3' and connect the rectangle corners as shown in figure.
Type 3DFace command
Specify all the four point of the top rectangle and press enter followed by hide.
Similarly do the 3DFace command to all the faces of the drawing
The dimensions layers was made default now and using the DIMLIM command the required dimensions was marked.
2. Create the 3d Model of an Isolated footing as shown in Figure.
Procedure -
Type UN and press enter
Under Drawing Units, select Archetectural (feet and inches)
Now the lower limit is set to 0', 0' and upper limit to 50', 50'
Type Z enter to zoom and A enter to all.
Now in settings selecting 3D Modelling and visual style control to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour.
Using the line command a square of size 1' was drawn.
Type Region and press enter, and select the square created to convert it.
Click on Extrude option in home tab and then select the object and click on Tamper, select the angle as b and and depth as 2".
Type Region and press enter, and select the tampered rectangle created to convert it into a region.
Now extrude the rectangle at a depth of about 6".
The visual style control was changed to hidden
The dimensions layers was made default now and using the DIMLIM command the required dimensions was marked.
3. Create the 3D view of the AASTHO Type Girder.
Procedure -
Type UN and press enter
Under Drawing Units, select Archetectural (feet and inches)
Now the lower limit is set to 0', 0' and upper limit to 50', 50'
Type Z enter to zoom and A enter to all.
Now in settings selecting 3D Modelling and visual style control to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour.
Using the line command and given dimensions the points was plotted and the following image was obtained.
Now using the Dimlim command the dimensions of the girder was made as shown.
The dimensions layer was made hidden after this.
Now Type Region and press enter, and select the Aastho type girder created to convert it into a region.
Now extrude the Aastho type girder at a height of about 10".
The visual style control was changed to hidden
The visual style control was changed to shaded with edges to obtain this view.
4. Create a 3d Model of a drop column with panel as shown in section and isometric view.

Procedure -
Under Drawing Units, select Archetectural (feet and inches)
Now the lower limit is set to 0', 0' and upper limit to 50', 50'
Type Z enter to zoom and A enter to all.
Now in settings selecting 3D Modelling and visual style control to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour.
sing the line command a square of size 4'-6" was drawn.
Type Region and press enter, and select the square created to convert it.
Click on Extrude option in home tab and then select the square and at a height of 2".
Type hide to hide the portions of the surface
Now a circle is drawn of diameter 3'-6" at the centre position of the rectangle.
Type Region and press enter, and select the circle created to convert it.
Click on Extrude option in home tab and then select the circle and click on Tamper, select the angle as 45 and and height as 2".
Now explode the tampered circle and convert the top circle into a region.
Click on Extrude option in home tab and then select the circle and at a height of 10'
The visual style control was changed to hidden
The visual style control was changed to shaded with edges to obtain this view.
5. Create the 3d model of a wall as shown in Figure. Consider wall thickness as 9”.
Procedure -
Type UN and press enter
Under Drawing Units, select Archetectural (feet and inches)
Now the lower limit is set to 0', 0' and upper limit to 50', 50'
Type Z enter to zoom and A enter to all.
Now in settings selecting 3D Modelling and visual style control to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour.
Using the line command and given dimensions the points was plotted and the following image was obtained.
Drafting was done in the same manner as done in Task 1.
Type Region and press enter, and select the model created to convert it.
Click on Extrude option in home tab and then select the model and at a height of 9".
The visual style control was changed to hidden
The visual style control was changed to shaded with edges to obtain this view.
Using the DIMLIM command the dimensioning
