Here is the object in 3D forth with its 2D drawing which we will learn to model in this postal service. I recommend you to switch to drafting and note workspace for this drawing, you tin likewise download CAD files for this tutorial here.

Step 1

Create the post-obit circles using CIRCLE command from describe panel of home tab, make sure circumvolve with radius 2.5 units has its center on the circumference of the circumvolve with radius 26 units.

Stride two

Select Polar Assortment from the Alter console of Dwelling tab and select two small-scale circles on the top of geometry. Now specify the center of the largest circle as the center of the array and enter 4 in the Number of Items field. You volition go an array like the i shown in the image beneath.

Pace 3

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

Step four

Trim all the geometries to brand it await like the epitome below.

Pace 5

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

Step 6

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

Step vii

Type PRESSPULL on the control line and click at a location within the geometry, make certain yous are clicking inside the geometry and not on the geometry. Enter the peak of 3 units on the command line and press Enter again.

7

This command will add the thickness of 3 units to the 2D geometry which nosotros have made so far and your drawing will look like the paradigm shown in a higher place.

Stride viii

Create a circle of R17 on the top of the object made in previous step, but for making a circle on top aeroplane yous need to make sure that dynamic UCS is turned on. Press F6 to plough on dynamic UCS so select circumvolve command and move your cursor to the top aeroplane and click at the middle of geometry for circle'southward center and enter a radius of 17 units and printing Enter again.

8

Step 9

Type EXT on the command line and press enter and then select the circumvolve nosotros have drawn in previous step and press enter over again. Enter a elevation of 5.five units and press enter once more to get out the extrude command.

9

Step 10

Now create another circle of radius 14 units with the aforementioned center on pinnacle of geometry which nosotros have drawn in the previous step and extrude it past iii.v units the same way we did previously.

10

Step eleven

Now blazon UNION and Press ENTER then select complete geometry and press enter again, this will ensure that all geometries become combined every bit a single unit.

Step 12

Create a circle of R11 on the peak almost surface of the geometry. Now type PRESSPULL on the command line and press Enter then click inside the circumvolve of radius 11 units and enter -12 as depth of geometry, this will make a hole in existing geometry.

Pace thirteen

Blazon F on the command line and press enter to start fillet command, blazon R on the command line and enter a radius of one.5 units for the fillet. At present select the edge between the apartment piece and the biggest cylinder as shown in the epitome beneath and press enter twice to get out the control.

12

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