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 :-

1. open autocad and change the setting to 3D modelling mode. make sure the units are in inches
2. make a layer and name it walls, window plan, window frame, window mullion, window glass, plinth and terrace. assign different colours for each layer.
3. convert all units into inches
4. take the 2d wiremesh view and take the plan option and draw the plan of the drawing as mentioned in the question using ortho mode and line option
5. offset the lines by 9 inch to make the walls
6. make the current layer as 'plinth' and using region option make the walls including the windows as a region
7. take extrude option and extrude this layer by 4 inch
8. now make current layer as 'walls'.enter ucs option and select the face option and click on the top face of the plinth layer.
9. copy the plan from the plinth layer and place it on top of the extruded plinth.
10. make the regions of the wall a region excluding the windows.
11. extrude the walls to a height of 10'.
12. now using rectangle option , draw a rectangle over the two windows, make it into a region and extrude to a height of 3'.
13. now enter ucs option and then take the face option and place it on top of the extruded walls.
14. copy the rectangle of the window on top, make it into a region and extrude it downwards 3'. now we have a hollow section in the place of window. using union option make the walls into a single figure.
15. make the current layer as terrace and copy the plan to the top of the wall and make the entire plan into a region.
16. now extrude the region by 5" to make the terrace. take the shaded opton to see the 3D view of the building drawn.
17. now to draw the windows. go back to the 2d wireframe drawing mode. take the ucs option and place it on the face of the wall where the windows should be.
18. there are two types of windows with different sizes. first the wall showing section BB is taken. draw a rectangle outside the surface of size 38" and height 4'. offset the sides by 3" and 4". trim off the unwanted lines to make 3 concentric rectangles. mak ethe current layer as window frame and select the outer recatngle to make a region. then make the current layer as window mullion and make the inside rectangle as another region.
19. now make the current layer as window frame and substract the inner region from the outer region.
20. make the current layer into window mullion and select boundary option to make the boundary of the inner recatngle . now using region option make it into a region. make the current layer into window glass and then make it into a region.making the current layer as window mullion , substract the window glass region from the window mullion region.
21. now making the current layer as window glass, make it into a region.
22. draw a handle in another layer with anither colour and repeat the same substraction process.
23. check if all the substraction is done correctly by going into the shaded option.
24. extrude the window frame by 4", window mullion by 3" and window glass by 2" inwards. now move the window mullion and window glass by 2" inwards and then the window glass by 1" inwards.
25. select the whole window and make it into a group by using group option. select the window and move it into the hollow section reserved for the window.
26. repeat the same for the window of section AA.
27. the resulting figures are shown below ie.:- section A-A, section B-B and the 3D drawing respectively.

10. copy the rectangle of the window to heights a s mentioned in the question., make it into a region and extrude it downwards and upwards as required so that we have hollow sections for the windows as shown in fig.1 below.
11. using union option make it into a single figure.
12. now take the ucs and place it on the face of the wall and draw a recatngle on the top of the building, offset it by 9" inwards and then mak eit into a region and extrude it by 4" towards th einside of the building.
13. take the shaded opton to see the 3D view of the building drawn.
14. now to draw the windows. go back to the 2d wireframe drawing mode. take the ucs option and place it on the face of the building wall where the windows should be.
15. there are two types of windows with different sizes. draw a rectangle outside the surface of size 3' and height 50". offset the sides by 2" and 3". trim off the unwanted lines to make the required window as shown in the window detailing. make the current layer as window frame and select the outer recatngle to make a region. then make the current layer as window mullion and make the inside rectangle as another region.
16. now make the current layer as window frame and substract the inner region from the outer region.
17. make the current layer into window mullion and select boundary option to make the boundary of the inner recatngle . now using region option make it into a region. mak ethe current layer into window glass and then make it into a region.making the current layer as window mullion , substract the window glass region from the window mullion region.
