Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim :

To draw the given Geometries as per given dimensions using tools and commands learned in AutoCAD software.

Drawing 1:

Procedure:

• Decimal unit of measurement is chosen as per instructions.
• The outline is first drawn using PLINE command and Direct entry method.
• For the angles in the outline the Relative polar coordinate system method is used.

• The centres of the circles are then marked using the LINE tool for getting accurate distance.
• Using endpoint of the line as center the circles are drawn using Centre,Radius method.
• The lines are then erased using ERASE.

Drawing 2:

Procedure:

• Architectural unit of measurement is chosen as per instructions.
• The outline is first drawn using PLINE command and Direct entry method.
• For the angles in the outline the Polar tracking is switched on and the Increment angle is set at 45,90 135....

Drawing 3:

Procedure:

• Engineering unit of measurement is chosen as per instructions.
• The outline is first drawn using PLINE command and Direct entry method.
• The straight lines are drawn as per dimensions provided and the diagram is closed forming the required angle in the diagonal.

• The centre point of the circle is calculated and using Center, Radius method the circle is drawn.

Drawing 4:

Procedure :

• The geometry is drawn using PLINE command and Direct entry method.

Drawing 5:

Procedure:

• The outline is first drawn using RECTANGULAR command and dimensions of the rectangles.

• In Object snap dialogue box the Geometric center check box is ticked.
• Using the Geometric center of the rectangles as the center and the provided Diameters the circles are drawn using Center, Diameter method.

Drawing 6:

Procedure:

• The first rectangle using RECTANGULAR command.
• Then it is split according to the given dimensions using LINE tool.

• The next diagram is drawn using PLINE command.
• The geometry of straight lines are fisrt drawn to scale and then the diagonal line is joined by snapping the endpoints.

• The next diagram is drawn as the same as the first using RECTANGULAR tool and lines to split them.

Drawing 7:

Procedure:

• Lines are drawn using PLINE tool and then filleted according to provided radius using FILLET command.
• The rectangles are drawn using RECTANGULAR command and placed in the given dimensions within the outline.

• The center required for the circle is arrived using line command and the midpoint of the line is turned on using OSNAP.
• CIRCLE command is used and Center,radius method is used for drawing the circles with given diameters and radius.
• Using the TRIM tool and the line the outer circle is trimmed to form and arc and the line is erased.
• The same procedure is used for the other side and the lines are filetted using FILLET to complete the drawing.

Drawing 8:

Procedure:

• A line is drawn using LINE command to act as center point for two circles.
• The circles are drawn using CIRCLE command and Center , Radius method.
• Lines cutting the circle through the middle vertically are drawn and TRIM command is used to trim off the circle to form arcs.

Drawing 9:

Procedure:

• A line is drawn using LINE command to act as center point for two circles.
• The circles are drawn using CIRCLE command and Center , Radius method.
• Lines cutting the circle through the middle vertically are drawn and TRIM command is used to trim off the circle to form arcs.
• They are then placed together to form the figure.

Drawing 10:

Procedure:

• A square is created using RECTANGULAR command.
• The square is offsetted using OFFSET tool.
• It is then copied using COPY tool.
• It is rotated by using polar tracking and ROTATE to get uniform angle.
• It is then moved using MOVE tool to the same center point as the first square.

Drawing 11:

Procedure:

• Using PLINE tool and Direct entry method the outline is drawn.
• The top line is then offseted using OFFSET command to form as baseline for the angles.
• The two angled lines are then created and moved using MOVE and placed on the created lines with the help of OSNAP.
• A square is created in the given points and then it is rotated using ROTATE and polar tracking to complete the diagram.

Result:

The above diagrams were created using various Tools and commands in the AutoCAD software according to the dimensions and instructions provided in the drawings.
