Creating 3D Isometric view of various structural elements in AutoCAD

1)

AIM:

• To create a 3D Isometric View of the building with plan and elevation given.

PROCEDURE:

• AutoCAD is opened with Imperial setting as default.
• In units of measurement Engineering is selected.
• Precision is set to 0'-0.0".
• Top view is selected in VIEW cube and plan is created with RECTANGULAR, TRIM, and OFFSET commands as per dimensions

• Using Layer properties manager from Layer panel in Ribbon the required layers are created and the components are set to appropriate layers.

• In the View cube Home icon is clicked and the BOUNDARY command and region option is selected to make walls into regions.
• The walls are then extruded by EXTRUDE command to required height.
• Layer is set to window and the rectangle is moved in Z axis to required height using MOVE command.
• It is then extruded to using EXTRUDE.
• The walls are then filled by created rectangles in the gaps, making them into regions by REGION command and extruding them using Extrude option in Ribbon.
• The window is then selected and erased
• The remaining wall layers are joined using UNION command.

• Using View cube and UCS command the Elevation A is set to the XY plane.
• RECTANGULAR, OFFSET and LINE command is used to create window as per dimensions
• They are Hatched using HATCH command.

ELEVATION A

• Using View cube and UCS command the Elevation B is set to the XY plane.
• The window is created using the same method as in elevation A.

ELEVATION B

FINAL RESULT:

A 3D Isometric View of the building has been created with plan and elevation given.

2)

AIM:

• To create the 3D View of the Building Façade as given in the plan and elevation.

PROCEDURE:

• AutoCAD is opened with Imperial setting as default.
• In units of measurement Engineering is selected.
• Precision is set to 0'-0.0".
• Top view is selected in VIEW cube and plan is created with RECTANGULAR, TRIM, and OFFSET commands as per dimensions
• Using Layer properties manager from Layer panel in Ribbon the required layers are created and the components are set to appropriate layers.

• In the View cube Home icon is clicked and the BOUNDARY command and region option is selected to make walls into regions.
• The walls are then extruded by EXTRUDE command to required height.
• Layer is set to window and the rectangle is moved in Z axis to required height using MOVE command.
• It is then extruded to using EXTRUDE.
• The walls are then filled by created rectangles in the gaps, making them into regions by REGION command and extruding them using Extrude option in Ribbon.
• The window is then selected and erased
• The remaining wall layers are joined using UNION command.

• Using View cube and UCS command the Elevation is set to the XY plane.
• RECTANGULAR, OFFSET and LINE command is used to create window as per dimensions
• They are Hatched using HATCH command.

• The drawing is then copied 3 times using COPY command and is placed on top of each other.
• To get the column and beam on top a polyline is created on the required path using 3P command.
• A rectangle is created and EXTRUDE -> Path command is given and the polyline is selected to form the required structure.

FINAL RESULT:

The 3D View of the Building Façade as given in the plan and elevation is created.

3)

AIM:

• To create the isometric 3d view of a stair with railing as shown in the plan and elevation.
• Assume the size of the balustrades and the hand rails.

PROCEDURE:

• AutoCAD is opened with Imperial setting as default.
• In units of measurement Engineering is selected.
• Precision is set to 0'-0.0".
• In the Top view the Outline of the stairs are created as per dimensions with LINE, OFFSET, COPY and TRIM commands respectively.

• Home icon is selected in the View cube.
• The plan of the stairs is rotated using ROTATE3D command.
• It is then created into a region using BOUNDARY command.
• It is extruded using EXTRUDE command as per dimensions.

• UCS -> Face command is given, a tread is selected as the face.
• The balustrade is created by drawing a circle using CIRCLE command on the tread and Extruding it using EXTRUDE command as per dimensions.
• It is then copied and pasted on all the treads using COPY command.

• A 3D polyline is drawn using 3P command as the path for the hand rail.
• A circle is drawn over the diameter of the balusrade and is extruded using the 3d polyline as the path by using EXTRUDE-> Path command to complete the hand rail.

FINAL RESULT:

The isometric 3d view of a stair is created with railing as shown in the plan and elevation.

4)

AIM:

• To create the 3D view of a Wall with spread footing and door opening .
• To create a rendered view of the model with materials as of your choice.

PROCEDURE:

• UN command is given and Type is given to Decimal and precision is set to 0.0.
• In top view Section of the Spread footing is created using RECTANGULAR, LINE, OFFSET and TRIM commands.
• Home icon is given and the drawing is flipped 90 degrees in the x axis using ROTATE3D command.

• The drawing is then converted into Regions by using BOUNDARY -> Region commands.
• Extrude icon is chosen from Ribbon, all the objects are selected and it is extruded as per the plan.
• From the Visual style dropdown shaded is selected and it is displayed.

• MAT command is used to open the Material browser.
• The surface is chosen and Materials are assigned as per need.
• It is then displayed in the Realistic view from Visual styles manager dropdown.

• RR command is given to render the drawing

FINAL RESULT:

The 3D view of a Wall with spread footing and door opening is created and rendered.
