* 2D plan of first floor
b. Making 2d plan into 3D
Step 9: creating region for extrusion
* Copy the 2d plan
* First create region by boundary command.
* For balconies region are created seperately , as the height of wall is 1.5m
* It is done by "BO" command.


Step 10: Creating different layers
* Make different layers for the full wall and half wall - walls of balconies , stairs and place the region in respective layers.

Step 11: Extruding the walls
* Select all the wall region ,full wall and extrude it by 3m.

* Extrude the half walls by 1.5m , all the balcony walls .

Step12: Creating window opening
* Create a rectangle at the bottom part of the window and extrude it 0.9m upwards till sill level.

* Also create a rectangle at the top and extrude it downwards 0.9m .


* Similarly extrude all walls and create window opening.
* Create opening for ventilator 0.5 x0.5m.
* Similarly create rectangle and extrude 0.9m from top and 1.6 from the bottom.

* Also extrude all ventilator openings as such.

* For lift door,create a rectangle at top and extrude -0.9m .
* For all the doors also create a rectangle at top and extrude 0.9m downwards, lintel level.

* For balconies also extrude -0.9m on top of the sliding doors.
* For kitchen balcony create a rectangle at top and extrude -0.45m . ( beam size).

* For the lobby opening , create rectangle and extrude -0.45m for the beam.

Creating windows
Step12: W1 ( 1.5x1.2)
* With ucs command plcae the ucs on the face of window
* Create a rectangle in the opening of the window.
* Move the rectangle to side to create frame mullions and glass.

* Create offsetof 0.5m to craete 3 panels.
* Offset 0.02m for the frame ,trim the edges.

* Offset 0.05m fro the mullions, trim off the edges.
* By "bo" command create a region for the frame.
* If it is selected fully use subtract command and subtract the frame region from the entire.
* Create a layer for window frame and insert the region to the layer.

* Extrude frame by 0.075m backwards.

* Mullions:
* Again with"bo" command create region for mullions .
* Subtract it from the entire region.
* Place it in the layer created for mullions.

* Extrude it by 0.03m.
For glass:
* Create region for glass by "BO" command.
* Make it a layer called galss- window

* Extrude it by 0.015m.
* Select the mullions and with move command move it by 0.015m. Command "M" ,specify the base point , then for second point give @0,0,-0.015, s that frame is projected outwards.

* Similarly select the glass and move it by 0.02m.

* Move or copy it and place in the opening of window.

* Group the window and place it whereever required.
* With "3d rotate" rotate the window by z axis and give angle as 90 degree.
Step 13: Creating window w2 (1x1.2)
* Do the same procedure in step 12 except there are 2 panels for w2.

Step 14: Creating ventilator v (0.5x0.5)m
* Draw a rectangle of 0.5 x0.5 and oofset 0.05for the frame.
* Create region for frame and glass and extrude it by 0.07 and 0.03

* Place it in the respective positions
Step 15: Creating a glass window in the main stair
* Create a rectangle offset 0.06m for the frame.
* Create region and extrude by 0.05 and 0.02 for frame and glass.

Step 16: Creating door
* Create a layer for door frame and door shutter
* Wit the help of polyline draw the outline of frame
* offset 0.05m for the thickness of frame.
* join the bottom of frame by line

* Then by join command make it a single profile
* Extrude it by 0.1m. , thickness of frame.

Step 17: Creating door shutter
* Create a profile by polyline by snapping end of the frame.
* Extrude it by -0.02 , thickness of frame.

* Move the shutter by move command
* move - select base point @0,0, -0.07 (0.1-0.02=0.07)

* Entire door is moved along the thickness of wall , by move comand and snapping

* Also create handle by sphere
Step 18 : Creating toilet doors and store doors(0.75x1.2 m)
* Create toilet door similar to the bedroom door
Step 19: Creating main doors (1x1.2m)
* Main door is also craeted same as other doors.
Step 20 : Creating lift doors
* Create a polyline and extrude it by 0.3m fro frame thickness
* Extrude 0.05m for the shutter thickness.

Step 21: Create window door for kitchen
* Create the frame by rectangle and offseting 0.05m .
* Create region by boundary command.
* Extrude the frame by 0.075m.
* Again create region for galss and extrude it by 0.02m.
Step 22: Creating sliding door for balcony. living and master bedroom
* Create a frame by rectagle , offset 0.05m and create region and extrude by 0.075.
* Similarly craete region for glass and extrude it by 0.02m.


Step 23: Creating 3d steps for main stair
* Go to top view and draw the section of stair with riser 0.175 and tread 0.25m.
* Waist slab thickness as 0.15m.

* Now create a region and extrude it 1.2m( width of stair)
* Place it in the proper place in the 3d model.

* Similarly for the next flight, place the ucson the face of the landing, then draw the section of stair., hide or turn off the layer of other objects to work smoothly.

* Create region by boundary and extrude 1.2m .

* for the landind slab to extend , create a rectangle on the side face of slab.

* EXtrude it till 1.2m width of 2nd flight.

* Similarly for the second flight also.

* Make it union by union command so that it becomes single seelction.
* If we need to edit the face , we can use solid edit and select the face and give extrusion and taper angle.
Step 24: Creating fire stair
*In top view draw the section of the fire stair
* riser-0.15m , tread -0.25m landing -1m waist slab -0.15m

* Create region and extrude by 1m.
* similarly draw the section of 2nd flight and extrude it.

Creating floor
Step 25: Creating mian floor
* Create layers for main floor, toilet floor and balcony floor,
* Go to top view 2d wireframe, and with the help of polyline draw the outline of floor inside the wall excluding the toilet and balcony with main floor layer.

* Similarly with polyline craete outline for the whole main floor area.

* Off the layers of main wall and half wall so that it becomes easy for selection.

* Now extrude the polyline by -0.15m , thickness of floor.

Step 26: Creating bathroom floor
* Create polyline in toilet floor layer and extrude by 0.15m.

* Place the ucs in each tread and copy it.

* For handrail, create 3d polyline over the ballusters and craete a circle of 0.03m .
* With sweep , seelct the circle then the polyline.

* Similarly create for the firestair.



Step 29: Creating ground floor
* Copy one flight of steps to the bottom of both the stairs.\
* Copy the wall also.

Step 30: Creating columns
