Creating various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad

1. Create a 3D Furniture element as shown in the Figure. Assume dimensions which are missing.

AIM: To create a 3D Furniture element as given in the figure and need to assume dimensions which are missing in the drawing.

INTRODUCTION: -

• 3D CAD, or three-dimensional computer-aided design, is technology for design and technical documentation, which replaces manual drafting with an automated process.

COMMANDS USED: -

• Line command
• Rectangle command
• UCS command
• Dim linear command
• Region command
• Extrude command
• Subtract command
• Box command
• Units command
• Dim style command
• 3Dface command
• 3Dorbit command
• Hide command
• Explode command
• Move command
• Copy command
• Dist. command

Procedure:

• Open AutoCAD, select imperial as the units are in feet and inches. Go to units’ command and set it to engineering, so that feet inches can be inserted.
• Create a box by clicking from the toolbar or box command, click on length, give the length as 3' and width as 2'6". Height is to be specified, give the height as 2'6".
• Select the front face, command "UCS" give the x and y coordinate in the front face horizontally and vertically respectively or click on face and select the front face. Type the command "PLAN" so that the front face is aligned correctly.
• Draw a line of 2" from the right side of the front view. By rectangle command, draw a rectangle of dimension 32" and 2'4" (as the thickness is given as 2")
• Move the rectangle to the line drawn earlier 2" from the right of the face.
• Delete the line created earlier. Now with command "3do" orbit the object and select the rectangle.
• Extrude the rectangle to -z axis 2'4" leaving 2" thickness. Now give the command "Subtract" select the larger object then the smaller extruded rectangle in 2d wireframe model.
• Dimensions are given by dim linear command by switching the UCS.
• 
• 
• 
• 

Result: The 3D model of furniture element is created.
