Here is the object in 3D along with its second drawing which we will learn to model in this mail. I recommend you to switch to drafting and annotation workspace for this cartoon, you can also download CAD files for this tutorial here.

Stride 1

Create the following circles using CIRCLE command from draw panel of home tab, make sure circumvolve with radius two.5 units has its center on the circumference of the circumvolve with radius 26 units.

Step two

Select Polar Assortment from the Modify panel of Home tab and select two small circles on the summit of geometry. At present specify the middle of the largest circumvolve every bit the heart of the array and enter 4 in the Number of Items field. You will get an assortment like the i shown in the epitome below.

Step 3

Delete the biggest circle and select FILLET command now enter R on the command line and blazon 7 as the fillet radius. Now use this fillet at the intersections of the circumvolve with R2.five and R22.five as shown in the paradigm beneath.

Step 4

Trim all the geometries to make information technology look like the epitome below.

Step 5

Type J on the command line and press enter then select complete geometry and press enter again. This will join all external second segments into a single unit. Yous may need to repeat the Bring together control couple of times to join the geometry completely.

Step 6

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

Step 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 summit of 3 units on the command line and printing Enter once again.

7

This command will add together the thickness of 3 units to the 2D geometry which we have made and then far and your drawing will await like the image shown to a higher place.

Step viii

Create a circle of R17 on the pinnacle of the object made in previous footstep, but for making a circle on top aeroplane yous demand to brand sure that dynamic UCS is turned on. Press F6 to plough on dynamic UCS then select circle control and move your cursor to the height plane and click at the centre of geometry for circle's center and enter a radius of 17 units and printing Enter again.

8

Step 9

Type EXT on the command line and press enter then select the circle we accept fatigued in previous step and press enter again. Enter a height of 5.5 units and press enter again to exit the extrude command.

9

Step 10

Now create another circumvolve of radius fourteen units with the aforementioned center on top of geometry which we take drawn in the previous step and extrude it by 3.5 units the same manner we did previously.

10

Pace eleven

Now type UNION and Press ENTER and so select complete geometry and printing enter once more, this will ensure that all geometries become combined as a single unit.

Step 12

Create a circle of R11 on the top most surface of the geometry. Now type PRESSPULL on the command line and press Enter and so 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 13

Blazon F on the command line and press enter to outset fillet command, blazon R on the command line and enter a radius of ane.5 units for the fillet. Now select the border betwixt the flat piece and the biggest cylinder as shown in the epitome beneath and press enter twice to exit the command.

12

The final geometry will expect similar the prototype shown to a higher place. Hope you enjoyed this tutorial if you lot have whatever questions regarding this tutorial let me know in the comments beneath.
