Creating 3D Isometric view of various structural elements in AutoCAD
AIM:
Creating 3D Isometric View of Various Structural Elements in AutoCAD.
OBJECTIVE:
To Create 3D model and View of:
- Isometric View of the building with plan and elevation given.
- 3D View of building Façade in plan & elevation, also detail of Window.
- 3D View of a Stair with railing shown in plan & elevation.
- 3D View of a Wall with spread footing & create a rendered view of the model with materials.
Commands used:
Line, Rectangle, Dim linear, 3Dface, 3D orbit, Solid edit, 3Dmirror, 3Drotate, Extrude, Offset, UCS, Box, Union, Subtract, Move, 3D orbit, Camera.
INTRODUCTION:
- An Isometric drawing is a 3D representation of an object, room, building or design on a 2D surface.
- One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted.
- This is due to the fact that the foreshortening of the axes is equal.
- In an isometric drawing, the object appears as if it is being viewed from one corner, with the axes being set out from this corner point.
- Isometric drawings being with one vertical line along which two points are defined.
- Any lines set out from these points should be constructed at an angle of 30 degree.
PROCEDURE
1). AIM: - ISOMETRIC VIEW OF THE BUILDING WITH PLAN AND ELEVATION GIVEN.
Step-1: First we have to draw the rectangle using Command: REC.
Next, we have to draw the two windows of sizes of 3’ x 9” and 9” x 3’-2’’.

Step-2: Now we draw the elevation of A and the elevation of B.
We draw the given elevations using the line command and we put the dimensions using the dim linear command.

Step-3: First we draw the window of the size 3’ x 4’ as shown
We draw this window using the line command and extruded using the extrude command.

Step-4: Next, we draw the window of the size 3’-2’’ x 4’ as shown.
We draw this window using the line command and extruded using the extrude command.

Step-5: Next, we draw the walls using the extrude command as shown.
Next, we use the layers for providing the colors to them.
Next, we attach the created windows to the walls as shown.

PROCEDURE
2 ). AIM: -3D VIEW OF BUILDING FAÇADE IN PLAN & ELEVATION, ALSO DETAIL OF WINDOW.
Step-1: Here first have to draw the rectangle using the command: REC
Next, we have to draw the window of size 3’-2’’ x 9’’.

Step-2: Next, we use the region command and select the objects, then press enter.
Then after total objects will become the one region
Next, we need to extrude the plan using command with the height of 10’-10’’.
Next, we need to subtract the four portions vertically in a building façade with the distance 5’-11’’ with the window size of 3’ x 4’.

Step-3: Next, we use the union command and press enter.
Then after select the total drawing and press enter.
Next the window portion will be clearly visible in the building façade as shown.
Step-4: Next, we select the custom visual style as shaded with edges, as shown.
Step-5: Next provide the layers for the building façade of Ocean blue colors shown.
Step-6: Next, we close the top surface of the building façade using the extrude command as shown.
Step-7: Next w draw the window of the size 3’-2’’ x 4’ as shown

We draw this window using the line command & extruded using the extrude command.
Step-8: Now put the building façade in 3d isometric view using the 3dorbit command as shown.

PROCEDURE
3). AIM: 3D VIEW OF A STAIR WITH RAILING SHOWN IN PLAN & ELEVATION.
Step-1: First we set units as architectural and take the precision as 0’-0’’.
Next, we draw the stairs using the line command.
We draw the stairs with the riser of 6’’ and tread of 1’ as shown.

Step-2: Next, we use the 3dorbit to rotate the figure from the step-1.
Next, we use the extrude command to extrude the rotated figure to form the stair in 3d view.

Step-3: Next, we draw the railing using the circle command and sweep command.
Next, we show stairs in the side view using the 3drotate command.
Step-4: Now put the stair in the 3d isometric view using the 3dorbit command as shown.

PROCEDURE
4 ). AIM: 3D VIEW OF A WALL WITH SPREAD FOOTING & CREATE A RENDERED VIEW OF THE MODEL WITH MATERIALS.
Step-1: First we set the units as decimal and take the precision as 0.
Next, we have to draw plan of wall spread footing with given dimensions as shown.

Step-2: Next, we draw the 3d isometric view of the wall with spread footing using the extrude command as shown.

Step-3: Next provide the layers for the wall with spread footing with different colors for different parts, as shown.

Step-4: Next, we provide the different materials for the wall with spread footing, as shown.
Step-5: We select the camera and put it in the required position and then press enter.
Next click on the camera then the small tab will appear at the top of the left corner, as shown.

Step-6: Finally, we select the render option and then slowly it changes to the rendering view as shown

RESULT:
- The given Isometric View of the building with plan and elevation is drawn successfully in the AutoCAD in detailed manner.
- The given 3D View of building Façade in plan & elevation, also detail of Window is drawn successfully in the AutoCAD in detailed manner.
- The given 3D View of a Stair with railing shown in plan & elevation and drawn successfully in the AutoCAD in detailed manner.
- The given 3D View of a Wall with spread footing & create a rendered view of the model with materials is drawn successfully in the AutoCAD in detailed manner.
