Here is the object in 3D along with its 2D drawing which we volition learn to model in this post. I recommend you to switch to drafting and annotation workspace for this drawing, you can also download CAD files for this tutorial here.

Footstep ane

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

Step 2

Select Polar Assortment from the Modify panel of Abode tab and select two small circles on the top of geometry. At present specify the eye of the largest circle every bit the centre of the array and enter 4 in the Number of Items field. You will go an assortment like the i shown in the paradigm below.

Step three

Delete the biggest circle and select FILLET command at present enter R on the command line and blazon 7 every bit the fillet radius. Now employ this fillet at the intersections of the circle with R2.5 and R22.5 as shown in the image below.

Step 4

Trim all the geometries to go far await like the image below.

Step five

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

Step 6

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

Step 7

Type PRESSPULL on the control line and click at a location inside the geometry, make sure you are clicking within the geometry and not on the geometry. Enter the acme of 3 units on the control line and printing Enter again.

7

This command will add the thickness of 3 units to the 2d geometry which nosotros accept made then far and your drawing will look like the image shown to a higher place.

Stride 8

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

8

Step nine

Type EXT on the command line and press enter and then select the circle we have drawn in previous pace and press enter again. Enter a height of 5.five units and press enter again to exit the extrude command.

9

Step ten

Now create another circle of radius xiv units with the same heart on tiptop of geometry which nosotros accept fatigued in the previous step and extrude information technology by 3.v units the same way nosotros did previously.

10

Step 11

Now type Spousal relationship and Printing ENTER then select complete geometry and printing enter over again, this will ensure that all geometries get combined equally a unmarried unit.

Step 12

Create a circumvolve of R11 on the top most surface of the geometry. Now type PRESSPULL on the command line and printing Enter so click inside the circumvolve of radius xi units and enter -12 as depth of geometry, this volition make a hole in existing geometry.

Stride 13

Type F on the command line and printing enter to commencement fillet command, blazon R on the command line and enter a radius of 1.5 units for the fillet. Now select the edge 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 similar the image shown above. Promise you enjoyed this tutorial if yous have any questions regarding this tutorial allow me know in the comments beneath.
