Hither is the object in 3D along with its 2d cartoon which we will acquire to model in this postal service. I recommend you lot to switch to drafting and annotation workspace for this drawing, you tin also download CAD files for this tutorial here.

Step 1

Create the post-obit circles using CIRCLE command from draw console of home tab, make sure circumvolve with radius ii.5 units has its center on the circumference of the circumvolve with radius 26 units.

Pace two

Select Polar Array from the Modify panel of Home tab and select 2 small-scale circles on the meridian of geometry. Now specify the center of the largest circumvolve as the heart of the assortment and enter iv in the Number of Items field. Y'all volition get an array similar the ane shown in the prototype below.

Pace iii

Delete the biggest circumvolve and select FILLET command now enter R on the command line and type seven as the fillet radius. At present apply this fillet at the intersections of the circle with R2.5 and R22.five equally shown in the image beneath.

Step 4

Trim all the geometries to make information technology look similar the epitome beneath.

Footstep 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. You may demand to repeat the Join control couple of times to bring together the geometry completely.

Step half-dozen

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 control line and press Enter again.

7

This command will add together the thickness of iii units to the 2D geometry which nosotros have made so far and your drawing volition wait like the prototype shown above.

Stride viii

Create a circumvolve of R17 on the height of the object made in previous step, but for making a circle on top plane you demand to make sure that dynamic UCS is turned on. Printing F6 to plough on dynamic UCS and then select circle command and move your cursor to the top plane and click at the heart of geometry for circle's center and enter a radius of 17 units and press Enter over again.

8

Step 9

Blazon EXT on the control line and press enter and so select the circle we have fatigued in previous step and press enter once more. Enter a height of five.5 units and press enter once more to get out the extrude command.

9

Step x

Now create another circle of radius 14 units with the aforementioned centre on top of geometry which we have drawn in the previous footstep and extrude it by 3.v units the aforementioned fashion we did previously.

10

Pace xi

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

Stride 12

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

Stride 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 ane.five units for the fillet. At present select the border between the flat piece and the biggest cylinder as shown in the prototype below and printing enter twice to exit the control.

12

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