Further Commands to be taught

Zoom – All/Center/Dynamic/Extents/Previous/Scale/Window Pan

Exercise 2: Set limits to 0,0 (lower left) and 45,45 (upper right) and set grid spacing to 1 and snap to 1 And draw all the below figures. Use Line command, Ortho off / on, Snap on/ off. May use Zoom command also to zoom some area.

Hope you have enjoyed the first day. Good luck

Day-2 (3 hours)

Absolute Coordinates Relative Cartesian Coordinates Relative Polar Coordinates Object Snap Polar Snapping POLAR & Direct Distance Entry Pick box Selections Options & Oops Command Redraw & Regen Blips Auto tracking Aperture

Exercise 3: After learning the coordinate systems and methods to draw, draw the same figures given in exercise-2 using the below methods 1. Direct Distance method (for figures which do not have inclined lines)

2. Absolute coordinate methods method (Draw the figure in your notes and mark

absolute (x, y) coordinates and then draw all the figures given in exercice-2.

3. Use relative polar coordinate system (@ length < Angle) and draw all the figures in

Ex-2

4. Use relative – absolute coordinate method and draw all the figures in the same sheet.

Exercise 4: After completing practice on coordinate systems and methods to draw, use

combinations of any method and draw the below figures, by setting the limits accordingly.

Ex: If the figure is of size 3 x 2, limits may be set to 5,5. If it is 3000, 2000, the limits may

be set to little higher than that.

Day-3 (3 hours) Drawing Circles. Pick the center and give the radius Pick the center and give the diameter Pick any 2 points (on the circumference) Pick any 3 points (on the circumference) Tangent – Tangent – Radius Tangent – Tangent – Tangent.

FIG-TTR

Practice 1) Draw a circle by picking any point as center and by feeding some diameter. 2) Set Limits to 100, 100. Draw a circle with center 50,50 – Diameter 50, 40, 30, 20,

10 – 5 circles. 3) Draw Figure C2P3P (A circle with 2 points option, B circle with 3 points option) 4) Draw FIG-TTR – Set limits to 400,450, Draw Circle A with center @ 100,100-

Radius 50, Circle B with center @ 300,100- Radius 50, Then draw 1 thru 4 with TTR Option – radii varying from 50 to 125 @ increment of 25.

5) Set limits to 400,450, Draw circle-1 with center point 100,100-Radius – 50, Draw circle-2 with center point 300,100-Radius – 50, Draw another Circle with center 200, 300 and Radius-50. Now you would get 3 circles in a triangular fashion. NOW Draw a circle with TTT option. You would get a circle amidst all the previous 3 circles.

9

Draw a rectangle for reference and practice all the options for drawing an arc as shown below. While drawing the below arcs, the start point are taken as the corners of the rectangle and the center point is taken at the intersection point of lines passing thru mid points of sides of the rectangle. To identify this, use OTRACK utility.

AutoCAD- 3D Modeling Who Should Attend All experienced AutoCAD® users who can benefit from the use of AutoCAD® ’s 3D features. (Make sure whether you have taken AutoCAD-3D Modeling Course, before going ahead from here)

Summary AutoCAD® ’s three-dimensional drawing capabilities make it a practical modeling program for a variety of applications and disciplines. Yet learning to work in 3D on a 2D-display device is a major challenge. This course is designed to introduce users who are proficient with AutoCAD® ’s 2D commands to the tools available for modeling in three dimensions. The class will start with 3D fundamentals, introduce surface creation, and solids modeling.

Objectives Upon completion of this course, attendees will be familiar with the 3D capabilities of AutoCAD®, and will know how to create, modify, and display 3D drawings. For maximum benefit, each attendee should be provided with practice time during the two weeks following this class. Given 20 hours of post-class practice and review, A student should be able to use AutoCAD® to create and update 3D drawings.
