A sample AutoCAD 3D practice drawing tutorial

Last Updated: December 8th, 2022By Categories: AutoCAD

Here is the object in 3D along with its 2D drawing which we will 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.

Step 1

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 circle with radius 26 units.

Step 2

Select Polar Array from the Modify panel of Home tab and select two small circles on the top of geometry. Now specify theย center of theย largest circle as the center of the arrayย and enter 4 in the Number of Items field. You will get an array like the one shown in the image below.

Step 3

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

Step 4

Trim all the geometries to make it look like theย image below.

Step 5

Type J on theย command line and press enter then select complete geometry and press enter again. This will join all external 2D segments into a single 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 style to Shaded from Views and Visual styles panel of Visualizeย tab.

Step 7

Type PRESSPULL on the command line and click at a location inside the geometry, make sure you are clicking inside the geometryย and not on the geometry. Enter the height 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 we have made so far and your drawing will look likeย the image shown above.

Step 8

Create a circle of R17 on the top of the object made in previous step, but for making a circle on top plane 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 theย top plane and click at the center of geometry for circle’s centerย and enter a radius of 17 units and press Enter again.

8

Step 9

Type EXT on the command line and press enter then select the circle we have drawn in previous step and press enter again. Enter a height of 5.5 units and press enter again to exit the extrude command.

9

Step 10

Now create another circle of radius 14 units with theย same center on top of geometry which we have drawn in theย previous step and extrude it by 3.5 units the same way we did previously.

10

Step 11

Now type UNION and Press ENTER then select complete geometry and press enter again, this will ensure that all geometries get combined as aย single unit.

Step 12

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

Step 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 edge between the flat piece and the biggest cylinder as shown in theย image below and press enter twice to exit the command.

12

The final geometry will look 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.

    If you swap step 3 and 4, you’d have almost 3 times less trimming to do…

    Also, I couldn’t figure out how to fillet in step 3 without exploding the polar array first…

    I’m stuck at stage 4 not all the edges are being trimmed

    • ram November 1, 2019 at 12:37 pm - Reply

      u have to select each one. note that trim command can be used where extension of the line is available to the next line. if not trim command not applicable for single line. go through youtube u can clear your doubts.

    My quary in generate a hole in subject by pressfull. I tried pressfull but it doesn’t work.

    • svs October 23, 2018 at 11:45 am - Reply

      use union command first and make it a single part. then presspull it.
      its done…

      You have to Explode the elements in the polar array first , then it works a treat.

      can’t find the center of the geometry, Dynamic UCS is on at step 8
