Autocad 3d Practice Drawings Pdf
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 the center of the largest circle as the center of the array 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 the command line and type 7 as the fillet radius. Now apply this fillet at the intersections of the circle with R2.5 and R22.5 as shown in the image below.
Step 4
Trim all the geometries to make it look like the image below.
Step 5
Type J on the 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 Visualize tab.
Step 7
Type PRESSPULL on the command 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 command line and press Enter again.
This command will add the thickness of 3 units to the 2D geometry which we have made so far and your drawing will look like 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 the top plane and click at the center of geometry for circle's center and enter a radius of 17 units and press Enter again.
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.
Step 10
Now create another circle of radius 14 units with the same center on top of geometry which we have drawn in the previous step and extrude it by 3.5 units the same way we did previously.
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 a single unit.
Step 12
Create a circle 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 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 the image below and press enter twice to exit the command.
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.

Tyoe osnap and select all the object snap modes.
teşekkürler türkiyeden selamlar ..fakat niçin tek tek çizim leri ayrı ayrı çizip katı hale getiriyorsunuz .aslında hepsini aynı anda çizip daha sonra uzatma ve içi boşaltmayı yapabilirsiniz ben ZW3d 2021 kullanıyorum saygılar sunuyorum
I am stuck in Step 2. How can I find the center of the largest circle?
What is the name of the object?
Tyoe osnap and select all the object snap modes.
done… thanks..it is useful to learn different comments & 3D..
Do you have vid tutorial for this?
stuck at Step 13. cant fillet
first union command apply the object
i'm struck in step 6 and step 7
Brief,concise,precise and very informative guidelines.
I'm stuck at stage 4 not all the edges are being trimmed
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.
Thankyou,
I am learned some important think in my life
Thank you very much for the clear and precise stages. Ken S
you're so great.
Thank so much for sharing
I've learned a lot.
God bless, and hoping that your going to share more and more steps in creating 3d objects form simple to complex.
Am stuck with step 13. Have tried using various visual styles but am not able to select the 'edge' stated?
Sorted, had to change workspace to 3D Modelling format.
Thank you so much.. I learn Something new. Thanks a lot.
My quary in generate a hole in subject by pressfull. I tried pressfull but it doesn't work.
use union command first and make it a single part. then presspull it.
its done…
please i'm having difficulties with step7. am not able to click the inside of the geometry, so am not able to put the 3unit.
sir, step 12 is not working. when i type -12 it will just extrude the circle
i don't know how to do the step 3? can you help me? thanks a lot
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
what this component called?
Just a drawing for you to practice
sir ,step 5 is not working
Please do edit polar array and select any one side then edit it to join it will work.
