Creating 3D Isometric view of various structural elements in AutoCAD
1. Aim :
Creating 3D isometric view of the building with plan and elevation given
Procedure :
- Under Drawing Units, select Archetectural (feet and inches)
- Now the lower limit is set to O', O' 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, windows,text and lines was choosen with a colour
- Using the line command the Plan, Elevation A and Elevation B was drawn.
- The walls and windows was placed in two respective layers.
- Using the DIMLIM command the dimensioning was completed.
- Using the single line text all the required texts was also made.

- A copy of plan layout is taken to draw the 3D image.
- All the layers exept the wall and window layer was turned off.
- The south west ismetric view is made the default view.

- Type BO to open the boundary command
- Dialogue box will open
- Click on > Pick a point
- Click on the internal portion of wall and press enter
- Click on the extrude option from from the home tab.
- Select object> Click on the walls
- Specify extrude height > 10'10" and press enter
- Change the visual style control > Shaded
- It will shows the following result


- The next task is to project the windows for that
- Type REC and draw a rectangle on top of the window.
- Click on the extrude option from from the home tab.
- Select object > Click on the rectangle
- Specify extrude height > 3' and press enter
- Use the Extrude, Substract and union command to finish and place the window.
- In the similar way the other window was also created.
- Change the visual style control > Shaded
- It will shows the following result

- Creating Elevation Windows.
- Change the current layer to Window Frame.
- Type UCS and click on face and select the face having 3' wide window
- Draw a rectangle of dimension 3,4'
- Offset the rectangle to inside to distnce of 3"
- Offset the inside rectangle to inside at a districe of 4"
- Start the boundary command and click on pick points
- Click inside the window frame area and press enter
- Type SUBTRACT command
- Select the bigger region and then select the smaller regions to subtarct them.
- Follow the same procedure for all the three boxes.
- In the same manner window mullion layer and window glass layer was made

- Now using the MOVE command place the window at the correct position as shown.
- The floor area was also made into a region and a suitable colur color was provided to it.

- A default layer for both dimension, windows,text and lines was choosen with a colour.
- Using the line command the Plan, Elevation A and Elevation B was drawn.
- The walls and windows was placed in two respective layers.
- Hatching with pattern was used to represent the walls.
- Using the DIMLIM command the dimensioning was completed.
- Using the single line text all the required texts was also made

- A copy of plan layout is taken to draw the 3D image.
- All the layers exept the wall and window layer was turned off.
- The south west ismetric view is made the default view.
- Type BO to open the boundary command
- Dialogue box will open
- Click on> Pick a point
- Click on the internal portion of wall and press enter
- Click on the extrude option from from the home tab.
- Select object> Click on the walls
- Specify extrude height > 9'11" and press enter
- Change the visual style control > Shaded
- It will shows the following result

- The next task is to project the windows for that:
- Type REC and draw a rectangle on top of the window.
- Click on the extrude option from from the home tab.
- Select object> Click on the rectangle Specify extrude height > 3' and press enter.
- Use the Extrude, Substract and union command to finish and place the window.
- In the similar way the other window was also created.

- Offset the inside rectangle to inside at a distnce of 3"
- Start the boundary command and click on pick points
- Click inside the window frame area and press enter
- Type SUBTRACT command
- Select the bigger region and then select the smaller regions to subtarct them.
- Follow the same procedure for all the three boxes.
- In the same manner window mullion layer and window glass layer was made

- Now using the MOVE command place the window at the correct position as shown.
- The building is made of four floors ans each floor layout is same.
- So the ground floor is copied and stacked on top of each other as shown
- The upper part of building was then drawn using line command, converted into region using the boundary command and finally extrude command was used to extent it

- To draw the hand rails.
- A circle of radius .75" was drawn.
- A circle with same centre and of radious .4" was drawn.
- .4" circle is extruded to a height of about 3'-2 and the .75" circle was extruded to a height of 2'
- The cylindircal tube of larger dia circle is raised to a height of about 6".
- Now a sphere of radius 1" was drawn placed at the centre of the larger dia cylinder.
- Using the Union command al of them was made into a single unit ans then it was placed on steps as required.
- Draw a polyline connecting all the top edges of hand rails.
- Draw a circle of diameter 2" on top of the first hand rail.
- Create a region of the circle drawn and do a Sweep command.
- Select the circle as object to sweep.
- Select the poly line drawn as path of sweep as shown in figure.
- Copy the same and place them at equal intervals as required.
