Week-2
Learning about aboout CAD designing software
Our task for this week was to learn about the different CAD softwares. ( CAD software are used for designing 2D and 3D objects for better understanding.) -For this we had to use 3 different softwares for designing in which i selected Fusion 360, Rhino3D and Correl -But due to problem in my laptop i could not download the two software so i started my work with Fusion 360. -CAD software for 3D designing: Fusion 360. (You have to make a student account for availing 3 years permission)
-I will get back to you with documentation of other two softwares. Till then go through the below documentation and learn about Fusion 360.
-I installed the software. And then found a tutorial on youtube to learn about the tools of the software. Youtube link
Design-1/
-I decided to make a 2D design of my new gaming mouse.Step-1
-First of all for starting any design in cad make a rough sketch of it on paper. This will help you make the design in the software faster and without confusion.
Step-2
-Select the top plane to make your design.
Step-3
-Make a rectangle of the same dimension of the mouse. (140*70)
Step-4
-Use the line function and with approx distance make the front slant cut of the mouse. -(Shortcut key for using line function is:- "L" from keyboard)
Step-5
-Further observing the mouse and respective to design you want use the line function and make the design. -Doing this you i got the below ddesplayed result.
Design-2
-Next, by observing the surrounding i decided to make a bowl.Step-1
-Again a select a plane. -This time i selected the Y-axis plane as it was the correct way to make this design.
Step-2
-After that i made a line drawing of the outside surface of the bowl.
Step-3
-Then i used the offset command. -Made a offset of "-0.15mm". -Shortcur Key for OffSet:- "O"
-Now the base design was ready.
Step-4
-Time for MAGIC. -Select the "REVOLVE" command from the 'CREATE' drop down in the bar.
Step-5
-select the recently made surface. and in the revolve setting make the 'Style' to 'Full' instead if 'Angle'. -The angle function can be used if you want the revolve till some angle only, but here we need it full.You will see the bix with angle of 360(degree).
-And yes there is the magic. The bowl is completed.
Design-3
-3rd design i wanted to make was a mug with straw in which we can drink milk or any juices.Step-1
-Select the top plane again as this is a flat,simple surface object.
-Make a cylinder with Height-90mm, Diameter-70mm.
Step-2
-Create a hole with the distance of 5mm from the circumference of cylinder. This will give us a tick wall of Mug.
Step-3
-Fillet the upper surface of the mug wwith dimension of - 0.25mm.
Step-4
-Now, the task was to make the handel. But it cannot be made simply on curved surface. -So, for getting a flat surface i made a small length cylinder and placed it on the surface of wall such that little part of it intersects the wall on inside.
-Copied the cylinder at the bottom also.
Step-5
-Now, for making of handel i used the revolve function. -Select the Front surface of the upper cylinder. -Select the axis around which it has to revolved. -Keep the angle of revolve "180" as we need it half till the other cylinder.
Step-6
-I used the coil command. -Select the bottom surface of the mug. The dimensions kept for the coil is shown in the image. -ThiS will give us the final product Mug with Straw.
