Creating 3D Isometric view of various structural elements in AutoCAD

AIM: 

To draw the given 3D figures. The drawing in the project is done with help of AUTOCAD software

PROCEDURE: 

• The units of the drawing sheet is set to Engineering precision.
• For the first question the dimensions lines are drawn using sperical co-ordinate system. 
• the plan of the given drawing is drawn in 2D wireframe. and the extrude in 3 dimensional.
• For the second question, the plan is drawn in 2d wireframe and extruding in z direction
• the windows sections are subtracted from the solid surface
• To draw staircase the plan is drawn in top view and rotated in the z direction 
• Boundary zone is created and the surface is extruded in x direction
• For the isolated footing, the plan is drawn and extruded in the z direction

RESULT: 

All the drawings are drawn from scratch and has been created using 3D modelling.
