1. Create a 3D Isometric View of the building with plan and elevation given.

AIM :

To Draw the 3D isometric view of the building as shown in the figure.

INTRODUCTION :

A plan view of wall of two elevation views of windows of both sides are given and they are to be converted into a 3D model , 2 window openings on both sides are given with details regarding the frame given dimensions , mullion dimensions and height , the thickness of bottom floor and top roof are also ggiven 4" and 6" respectively, and the height of floor is 10' , height of window from floor is 3'.

PROCEDURE :

Open AUTO CAD,

In start up settings , start from scractch select imperial ( feet and inches)

Open grid and snap settings

• changing snap and grid spacing 1'
• changing major line every grid line to 10
• turnoff adoptive grid

change the workspace setting from draft and annotation to 3d modelling,

Step 1:

Creating layers,

Step 2:

• Create a rectangle of dimensions 10'9"*10'9"
• offset the rectangle to inside of 9" of wall thickness,

• delete the left and bottom lines and extend them to the edges as shown in fig,
• Draw the window with dimensions 3'2" @ top and 3' on right side on shown in fig,

step 3:

Set ucs as world,

• create the boundaries of the wall using bo command
• extrude boundaries created to total height 10'10"

• select the wall and use group command to group together
• draw rectangle on both windows and change them bounfdaries using boundary command
• extrude both the rectangle at height 3'4" as shown

• darw the rectangle @ top of both the window as shown in, change them into boundaries using boundary command

type UCS click on face and select face having 3' wide window

• darw a rectangle a bottom part of the window with dimensions 3' 4'

type UCS click on face and select face having 3' 2" wide window

• darw a rectangle a bottom part of the window with dimensions 3'2" 4'

change the ucs back to world,

• extrude the rectangle drawn #@ top side to top edge of the window
• group all wall components together

Step 4:

Creation of elevation windows:

Window @ elevation A,

Change the current layer to 3d window frame,

type ucs click on face and select the face having 3' window,

• draw the rectangle @ 3' 4' , offset rectangle inside distance of 3" & 4",

• start the boundary commands click on pick points,
• click inside the window fframe area and press enter,
• start subtract command ,/ select the bigger region and then the smaller region to subtract them.
• follow the same procedure for all the boxes,

change the current layer to 3d window glass,

start boundary commands , click on pick points,

• click inside the window glass area and press enter
• all the layers are extruded to give window projection look as shown in fig,

Window @ Elevation B,

Change the current layer to 3d window frame,

type ucs click on face and select the face having 3' 2" window,

• draw the rectangle @ 3' 4' , offset rectangle inside distance of 3" & 4",
• start the boundary commands click on pick points,

• click inside the window fframe area and press enter,
• start subtract command ,/ select the bigger region and then the smaller region to subtract them.
• follow the same procedure for all the boxes,

change the current layer to 3d window glass,

start boundary commands , click on pick points,

• click inside the window glass area and press enter
• all the layers are extruded to give window projection look as shown in fig,

RESULT :

Initially all the layers necessary are created with respective line types and line weights ,

the plan view is drawn as shown in step 2, then from step 3 3d view is created with respective layers assigned , the UCS view is changed accordingly to make changes the 3d view and 3d dimensions , boundary command is used for creating region along the boundaries and extrude them , after the view is created the result is shown , the result consists of different views of the 3d model such as TOP VIEW, SW isometric VIEW , NE isometric VIEW, Windows .

* all dimensions are in feet and inches,

1. View 1,

SW Isometric,

4. Create the 3D view of a Wall with spread footing . Create the Door opening only. Assume the size of the parpaet and the coping. See the plans and elevation for the details. Also, create a rendered view of the model with materials as of your choice.

AIM :

To draw the 3D view of wall with spread footing as shown in the plan and elevation.

INTRODUCTION :

Aplan view and elevation view of the wall in the spread footing under it are given and they are converted into a 3D model. spread footing is a type of footing which goes along the lenght of the wall in the building , it is used as shallow footing type, plan view consists of horizontal dimensions of the footing and the wall, elevation views consists of the vertical dimensions, of different level of footing , height of 230mm thickness wall.

thickness level 1 of footing same as 230mm

copuing thickness of the level 2 is offset the 50mm than the thickness of the wall

thickness of level 3 is ofsset of 50mm then the thickness of level2

thickness of level 4 is offset of 120mm than the thickness of level 3,

PROCEDURE :

Open AUTOCAD,

In start up settings , start from scractch select metric ( meters and mm)

Open grid and snap settings

• changing snap and grid spacing 100
• changing major line every grid line to 10
• turnoff adoptive grid

change the workspace setting from draft and annotation to 3d modelling,

Step 1:

Creating layers,

LAYER ARE CREATED AS FOLLOWS,

step 2:

creating 2D plan view of wall with spread footing,

• change current layer to the wall
• darw the rectangle 670*7500
• offset the rectangle in side the distance 120mm,
• offset the offset the rectangle the distance 50mm as twice,
• explode all the offset rectangle,
• delete top and bottom of the exploded edges,
• extend all the rectangle to the top and bottom edges of outer rectangle
• @ the end select the individual lines change the layers,
• 

craeting door block,

• draw rectangle of dimension 50and 100 mm
• darw another rectangle of dimension 50*50 mm
• draw a linwe length of 850 mm from the edge
• darw an arc line of the door swing,
• convert the door into block

• edit the block and add flip parameters
• create door opening 900mm @ the middle,
• add the door block by rotating the door
• add the door shade using respective layers
• 

step 3: Creating elevation view,

• click on front view on the view cube.
• change the ucs to the front,
• cahnge the current layer to g.l
• darw a line of central length,
• offset the line to bottom 25mm
• offset the last offset line bottom to distance of 100mm
• cahnge the current layer to the wall
• darw thw rectangle 230*3300 from top left edges of ground level
• cahnge the current layer to roof level,
  darw roof thickness 150mm
• draw parapet wall of height 600 mm

Footing layers,

• Draw thr rectangle 230*600 below the ground level,
• draw the recatngle 230*400 below thw first level,
• draw the rectangle 430 * 400 below thw second level,

Change current layer to footing,

draw rectangle dimension 670*300 below thw third level,

trim the unnecessary edges

door ,

change the current layer to the door,

darw line along the length of door 230mm @ the g.l

• offset the line below the distance of 50mm below the ground level
• offset the distance 2100 above
• change the current layuer to the door shade
• darw the door shade, The end result of teh steps are follows

Step 4:

• Drawing 3D view of the section , for craeting 3D view initially boundaries are craeted,
• each boundaries is created with respective layers as current,

• the created boundaries are extruded to a distance of 7500 mm
• select the boundaries by creating the respective layers,
• door opening is added by drawing the rectangle @ the door location from the plan view
• then from extruded part the door region is subtracted
• similarly door shade is created with the opening above
• after door shade remaining layer is extruded

Step 5:

Rendering:

rendering is done by adding materials the 3d view

• material browser is used for adding materials to object,
• materials added for the component from the material browser as shown below ,
• box mapping is done to adjust the texture of the wall

Lights:

• Torch light is placed in front of the door, @ central distance with fall of angle 50 and hotspot angle as 80
• Distant light is also used.

Creating views:,

RESULTS :

The results consists of different views of the 3D model,such as

• view 1 (top view)

• view 2 ( right side view)

• view 3 ( SW Isometric)

Hidden view,

• view 4 ( cam front door view)

• Rendered view
