Hither is the object in 3D along with its 2nd cartoon which we volition larn to model in this post. I recommend you to switch to drafting and note workspace for this drawing, yous can also download CAD files for this tutorial hither.

1

Step one

Create the following circles using Circle command from depict panel of dwelling tab, make sure circumvolve with radius 2.5 units has its center on the circumference of the circle with radius 26 units.

Step 2

Select Polar Assortment from the Change panel of Home tab and select two pocket-size circles on the top of geometry. Now specify the center of the largest circumvolve as the centre of the array and enter four in the Number of Items field. You volition go an array like the one shown in the epitome below.

Step 3

Delete the biggest circumvolve and select FILLET command 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.five as shown in the image beneath.

Step 4

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

Stride v

Type J on the command line and printing enter then select consummate geometry and printing enter once more. This will bring together all external second segments into a single unit. You may demand to repeat the JOIN command couple of times to join 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 vii

Blazon PRESSPULL on the control line and click at a location inside the geometry, make sure you are clicking inside the geometry and not on the geometry. Enter the height of 3 units on the control line and press Enter again.

7

This command will add together the thickness of 3 units to the second geometry which we accept fabricated so far and your drawing will look like the image shown in a higher place.

Footstep viii

Create a circle of R17 on the peak of the object made in previous step, but for making a circle on top plane you need to brand sure that dynamic UCS is turned on. Press F6 to plow on dynamic UCS so select circle command and move your cursor to the top plane and click at the centre of geometry for circle'due south center and enter a radius of 17 units and press Enter over again.

8

Step 9

Blazon EXT on the command line and printing enter then select the circumvolve nosotros have fatigued in previous pace and press enter once more. Enter a acme of 5.v units and press enter again to exit the extrude command.

9

Footstep ten

At present create another circle of radius 14 units with the aforementioned middle on elevation of geometry which we have fatigued in the previous footstep and extrude it by iii.5 units the same style nosotros did previously.

10

Stride xi

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

Footstep 12

Create a circumvolve of R11 on the top well-nigh surface of the geometry. Now 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 pigsty in existing geometry.

Step thirteen

Blazon F on the command line and press enter to start fillet command, type R on the command line and enter a radius of 1.v units for the fillet. At present select the edge between the apartment piece and the biggest cylinder as shown in the image below and printing enter twice to exit the command.

12

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