Creating 3D Isometric view of various structural elements in AutoCAD

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

AIM AND INTRODUCTION : 3D Isometric View of the building with given plan and elevation given is to be created.

PROCEDURE IN DETAIL :

Plan of the building is created using the following command-

• RECTANGLE command
• Line command
• DIM (A/C) command

Elevation at A is created using following commands-

• XL (H/V) commands for reference lines from the plan in horizontal and vertical directions
• TRIM & DELETE commands for removing undesired lines
• OFFSET command is used for creating frame and panel of window
• DIM (A/C) command for dimensioning
• MTEXT(MT) command is used to create text

Elevation at B is created using following commands-

• XL (H/V) commands for reference lines from the plan in horizontal and vertical directions
• TRIM & DELETE commands for removing undesired lines
• OFFSET command is used for creating frame and panel of window
• DIM (A/C) command for dimensioning
• MTEXT(MT) command is used to create text

• Plan is converted to isometric view
• REGION command is used to create region on the wall portionlevations
• EXTRUDE command is used to create height of the wall as given in E

Windows are also extruded to the height of 10'-10" as given in elevation using REGION and EXTRUDE command

In top view 2D wire frame creating rectangle in window portion using RECTANGLE command and creating regions using REGION command a shown in the snap below-

In Custom view 2D wire frame window regions are extruded to the height of 4' as shown below using EXTRUDE command

Changing the view to Custom and shaded and assigning the windows different colors using SOLIDEDIT command for better identification of windows as shown below-

UNION command is used to combined the windows and other part as one solid as shown below-

SUBTRACT command is used to remove the solid windows from the entire solid to create opening for fixing frame and shutters of windows as shown-

Window frame and shutter is created using RECTANGLE and OFFSET command -

EXTRUDE command is used to assign thickness to the Window frame ( 5" assumed), Style ( 3" assumed) and shutter/panel (1" assumed) and seperating different components using MOVE command as shown-

Panel is fixed centrally to the Style using MOVE command and colours are assigned using SOLIDEDIT command as shown-

Style along with panel is fixed in window frame using MOVE and SOLIDEDIT commands-

Window is fixed centrally in the opening created in the wall using MOVE command

Another window is created and fixed at opening in the wall as per procedure followed in earlier step as below-

Hidden view-

X-Ray view-

Wire Framed view-

Conceptual view-

RESULT : Thus as desired 3D Isometric View of the building with given plan and elevation is created. Various steps have been narrated with snaps and .DWG file is attached for reference with file name " ACCHQ1.
