Here is the object in 3D along with its 2d drawing which we will acquire to model in this mail service. I recommend you lot to switch to drafting and note workspace for this drawing, you tin can as well download CAD files for this tutorial here.

Footstep 1

Create the following circles using Circle command from draw console of home tab, make sure circle with radius ii.5 units has its center on the circumference of the circle with radius 26 units.

Step ii

Select Polar Assortment from the Modify panel of Home tab and select ii small circles on the top of geometry. Now specify the center of the largest circle as the center of the assortment and enter 4 in the Number of Items field. Y'all will get an array like the 1 shown in the image below.

Step 3

Delete the biggest circle and select FILLET control now enter R on the command line and type 7 as the fillet radius. Now apply this fillet at the intersections of the circle with R2.5 and R22.v as shown in the image below.

Pace 4

Trim all the geometries to go far look like the image beneath.

Step 5

Blazon J on the control line and press enter and so select complete geometry and press enter again. This volition join all external 2D segments into a single unit of measurement. You may need to repeat the JOIN command couple of times to join the geometry completely.

Step half dozen

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

Pace 7

Type PRESSPULL on the command line and click at a location inside the geometry, brand sure you lot are clicking inside the geometry and not on the geometry. Enter the tiptop of three units on the control line and press Enter again.

7

This command will add the thickness of 3 units to the 2nd geometry which we have made so far and your drawing volition look similar the paradigm shown above.

Pace viii

Create a circumvolve of R17 on the top of the object fabricated in previous footstep, simply for making a circle on tiptop plane you need to make sure that dynamic UCS is turned on. Printing F6 to turn on dynamic UCS and so select circle command and move your cursor to the tiptop plane and click at the center of geometry for circle's middle and enter a radius of 17 units and press Enter once again.

8

Step 9

Blazon EXT on the control line and press enter then select the circumvolve nosotros have drawn in previous step and press enter again. Enter a height of 5.v units and printing enter again to exit the extrude command.

9

Footstep 10

Now create another circle of radius 14 units with the same eye on tiptop of geometry which we take drawn in the previous step and extrude it by 3.v units the same way we did previously.

10

Step eleven

Now type UNION and Press ENTER then select complete geometry and press enter again, this will ensure that all geometries get combined as a unmarried unit.

Step 12

Create a circumvolve of R11 on the meridian about surface of the geometry. Now blazon PRESSPULL on the control line and press Enter then click inside the circle of radius eleven units and enter -12 every bit depth of geometry, this will brand a hole in existing geometry.

Step xiii

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

12

The final geometry will look like the image shown above. Hope y'all enjoyed this tutorial if y'all accept any questions regarding this tutorial let me know in the comments below.
