Creating various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad
AIM: Creating various 3D Models like furniture, Footing , Girder , Column drop with panel and gable wall in Autocad.
Q1.Create a 3D Furniture element as shown in the Figure. Assume dimensions which are missing.

PROCEDURE:
Set the drawing units to Engineering units
Set the lower limit and upper limit as per the drawing requirement
Now in settings 3D modelling is selected and visual style control is set to 2D wireframe.
Type L and press enter
Specify the first point as anywhere in the drawing.
Specify next point:@0,0,-2'6" and press enter
specify next point:@0,3',0 and press enter
Specify next point:@0,0,-2'6"
Specify next point:@0,-2",0 and press enter
Specify next point:@0,0,2'4"
Specify next point:@0,-3',0 and press enter
specify next point:@0,0,-2'4"
Specify next point:@0,-2",0 and press ente

Draw a rectangle at the top of dimensions 2'2"x3' and connect the rectangles corners as shown in figure.
Type 3D Face command
specify all the four points of the top rectangle and press enter followed by hide.
Similarly do the the 3D face command to all the faces of the drawing

The dimensions layers was made default now and using the Dimlin command the required dimensions was marked

RESULT: The 3D furniture element is created using Autocad.
Q2. Create the 3d Model of an Isolated footing as shown in Figure.

PROCEDURE:
Type UN and press enter , under the drawing units select engineering unitys
Now the lower limit is set to 0',0' and upper limit to 50',50'
Type Z enter and A enter
Now in settings 3D modelling is selected and visual style control is set to 2D wireframe.
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 the Extrude options in home tab and then select the object and click on Tamper , select the angle as much required and depth as 2'.

Now Extrude the rectangle at a depth of about 6".
The visual style control was changed to hidden.

The dimensions layer was made default now an using the Dimlin command the required dimensions was marked.

RESULT: The 3D model of an isolated footing is created using Autocad.
Q3. Create the 3D view of the AASTHO Type Girder.

PROCEDURE:
Type UN and press enter , under the drawing units select engineering unitys
Now the lower limit is set to 0',0' and upper limit to 50',50'
Type Z enter and A enter
Now in settings 3D modelling is selected and visual style control is set to 2D wireframe.
Using the line command and given dimensions the points was plotted and the following image was obtained.
Now using the Dimlin command the dimensions of the girder was made as shown.
Now type Region and press enter , select the Aastho type girder created to concevrt into a region.

Now extrude the Aastho type girder at a height of about 10'.

The visual style control was changed to shaded with edges to obtain this view

RESULT: The 3D view of AASTHO girder is created using Autocad.
Q4.Create a 3d Model of a drop column with panel as shown in section and isometric view.

PROCEDURE:
Type UN and press enter , under the drawing units select engineering unitys
Now the lower limit is set to 0',0' and upper limit to 50',50'
Type Z enter and A enter
Now in settings 3D modelling is selected and visual style control is set to 2D wireframe.
Sqaure of 4'6" was drawn using command and region is created

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 the 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 is changed to shaded with edges to get the following image.

RESULT: The 3D model of drop column is created using Autocad tools.
Q5. Create the 3d model of a wall as shown in Figure. Consider wall thickness as 9”

PROCEDURE:
Type UN and press enter , under the drawing units select engineering unitys
Now the lower limit is set to 0',0' and upper limit to 50',50'
Type Z enter and A enter
Now in settings 3D modelling is selected and visual style control is set to 2D wireframe.
A default layer for both dimension and lines was choosen with a colour
Using line command and given dimension the points was plotted and the following image is obtained.
Drafting was done in the same manner as done in task 1.
Type region and press nter , an select the model created to convert it.

Click on extrude option in home tab and then select the model and at a thickness of 9".

The visual style control was changed to hidden and the dimesnions are given as per the requirement.

RESULT: The 3D model of wall is created by uisng Autocad tools.
