Here is the object in 3D forth with its 2d cartoon which we will learn to model in this mail. I recommend you to switch to drafting and notation workspace for this cartoon, you lot can besides download CAD files for this tutorial here.

Step 1

Create the post-obit circles using Circumvolve command from describe panel of home tab, make sure circle with radius 2.five units has its center on the circumference of the circle with radius 26 units.

Step ii

Select Polar Array from the Change panel of Home tab and select 2 modest circles on the top of geometry. At present specify the center of the largest circumvolve equally the middle of the assortment and enter four in the Number of Items field. Yous volition get an array similar the one shown in the image below.

Step iii

Delete the biggest circumvolve and select FILLET control now enter R on the command line and blazon 7 equally the fillet radius. Now apply this fillet at the intersections of the circle with R2.5 and R22.five every bit shown in the paradigm below.

Step 4

Trim all the geometries to make it look like the image below.

Step v

Type J on the command line and printing enter so select complete geometry and press enter again. This will bring together all external 2nd segments into a single unit. You may need to echo the Join control couple of times to join the geometry completely.

Pace half-dozen

Modify view to southwest isometric and visual style to Shaded from Views and Visual styles console of Visualize tab.

Stride 7

Type PRESSPULL on the command line and click at a location inside the geometry, make sure you are clicking inside the geometry and not on the geometry. Enter the height of 3 units on the command line and press Enter again.

7

This control volition add the thickness of three units to the second geometry which we take made so far and your drawing volition await similar the prototype shown above.

Stride viii

Create a circumvolve of R17 on the top of the object made in previous step, but for making a circumvolve on top plane you need to make sure that dynamic UCS is turned on. Press F6 to turn on dynamic UCS and then select circumvolve command and move your cursor to the meridian airplane and click at the center of geometry for circle's eye and enter a radius of 17 units and printing Enter again.

8

Step 9

Blazon EXT on the command line and press enter then select the circumvolve we have drawn in previous pace and press enter again. Enter a height of five.5 units and printing enter over again to exit the extrude command.

9

Footstep 10

Now create some other circle of radius 14 units with the same eye on superlative of geometry which we accept drawn in the previous pace and extrude it by 3.5 units the same way nosotros did previously.

10

Step xi

Now type Spousal relationship and Printing ENTER then select complete geometry and printing enter again, this will ensure that all geometries get combined as a unmarried unit.

Pace 12

Create a circle of R11 on the elevation most surface of the geometry. Now type PRESSPULL on the command line and press Enter then click inside the circle of radius xi units and enter -12 equally depth of geometry, this volition make a hole in existing geometry.

Step 13

Type F on the command line and printing enter to start fillet command, blazon R on the command line and enter a radius of 1.5 units for the fillet. Now select the edge between the flat piece and the biggest cylinder every bit shown in the image below and printing enter twice to exit the command.

12

The final geometry will look like the image shown above. Hope yous enjoyed this tutorial if you have any questions regarding this tutorial let me know in the comments below.
