Hither is the object in 3D along with its 2D cartoon which nosotros will acquire to model in this post. I recommend yous to switch to drafting and annotation workspace for this cartoon, yous can also download CAD files for this tutorial hither.

Stride 1

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

Step 2

Select Polar Array from the Modify console of Home tab and select two modest circles on the top of geometry. Now specify the center of the largest circle as the heart of the assortment and enter 4 in the Number of Items field. You will get an array like the one shown in the image beneath.

Stride three

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

Step four

Trim all the geometries to make it look like the epitome beneath.

Stride 5

Type J on the control line and printing enter then select complete geometry and press enter over again. This will join all external 2D segments into a unmarried unit. You may need to repeat the JOIN command couple of times to bring together the geometry completely.

Step vi

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

Step 7

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

7

This control will add together the thickness of 3 units to the 2nd geometry which we have made and then far and your drawing will await like the image shown above.

Step 8

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

8

Footstep 9

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

9

Stride 10

Now create some other circle of radius 14 units with the aforementioned center on top of geometry which we have drawn in the previous stride and extrude it past 3.5 units the same mode we did previously.

10

Stride 11

Now blazon UNION and Press ENTER then select complete geometry and press enter once again, this volition ensure that all geometries get combined equally a single unit of measurement.

Footstep 12

Create a circumvolve of R11 on the top most surface of the geometry. At present type PRESSPULL on the command line and printing Enter then click inside the circle of radius 11 units and enter -12 as depth of geometry, this will brand a hole in existing geometry.

Pace 13

Type F on the command line and press enter to start fillet command, type R on the command line and enter a radius of 1.5 units for the fillet. Now select the border between the flat piece and the biggest cylinder as shown in the image below and printing enter twice to get out the command.

12

The last geometry will await like the prototype shown higher up. Hope you enjoyed this tutorial if y'all have whatsoever questions regarding this tutorial permit me know in the comments beneath.
