RESULT:Geometry is drawn as 3D figure.

3. AASTHO TYPE GIRDER

Procedure:

• Open the AutoCAD software and go to the 3D modelling space for creating the geometry
• Set the units to imperial units which will show feet and inches
• Type the Command UNITS and set the units to engineering units.
• Type the Command DIMSTYLE and set the primary units to engineering and precision to 0’00”
• Now go to the 2-D wireframe
• Type the command LINE and give 1’ units in +y direction.
• Now from the upper point give 6” units in –x direction.
• Now do same at lower point by giving 6” units in same direction
• Now from the centre of the vertical line make a line of 3” in both the sides and join the line as a single line using the JOIN Command.
• Now move this line to 9” units in –x direction by using MOVE command and keeping orthogonal mode on
• Join the 6” horizontal line to this line.
• Now from 6” vertical line give the 1’3” in –x direction.
• Now from the 1’ vertical line, copy this line and move it to 2’6” in –x direction keeping orthogonal mode on.
• Extend this copied line by 3”from both the sides to make a 1’6” and join it by using the JOIN command.
• From this line give the offset of 6” in +x direction.
• Join the 1’3” lines to this line.
• Now from this last made 1’6” line give 6” units in –x direction from both the points.
• Now extend these lines to further distance.
• Now from the centre lower 1’6” line make a line 7” to both side and JOIN it to make 1’4” line.
• Now from this draw inclined lines cutting the 1’6” extended lines at the required desired angle as shown in the geometry.
• Now extrude the whole figure to the certain distance.
• Now type the command 3DFACE and select the planes which we want to hide.
• Now type the Command HIDE and select the 3D faces and click enter.
• Entire drawing is shown as a 3D Geometry.
• Type the Command UCS and take the UCS to the plane, where we have to do the dimensioning.
• Select the axis as per the planes on which we have to do the dimensioning.
• Do the dimensioning and go to the SHADED option.

RESULT: Geometry is drawn as 3D figure.

4. Drop Column with Panel

Procedure:

• Open the AutoCAD software and go to the 3D modelling space for creating the geometry
• Set the units to imperial units which will show feet and inches
• Type the Command UNITS and set the units to engineering units.
• Type the Command DIMSTYLE and set the primary units to engineering and precision to 0’00”
• Now go to the 2-D wireframe
• Type the Command Rec and give the dimension as 4’6”x4’6”
• Now from the centre of the rectangle line give the offset of 6”.
• Rectangle of 3’6”x3’6” is drawn.
• Now from this rectangle line give the offset of 10” in the inner side.
• Rectangle of 1’6”x1’6” is drawn.
• Now come to the 3d view.
• Now move the second rectangle to 6” in +z direction.
• Now move the 3^rd rectangle to 1’ in +z direction.
• Now from the lower rectangle (4’6”x4’6”) extrude it to 6” in +z direction.
• Join the 2^nd and 3^rd smaller rectangle from the edges.
• Type the command 3D face and select the planes join by 2^nd and 3^rd
• Use the Hide command and the hide the faces.
• From the centre of smaller rectangle draw a circle of 8” radius touching the smaller rectangle edges.
• Now extrude the circle to the 10’ units –x direction in the 3d view.
• Use the Command SOLID EDIT.
• Select the face option and then select the colour option.
• Give the colour to the required geometry.
• Do the dimensioning with the help of UCS command.
• Use the DIMLINEAR Command for dimensioning.

RESULT: Required geometry is made as per given.

5. Gable Wall

Procedure:
