Hello,

I’m very new to Shapr3d and am looking for some help. All I really need is for someone to teach me how to create tapered dowels that I can save as .stl files for importing to my CNC software.

Is there anyone that would be willing to spend a few minutes showing me how to do this, or maybe even directing me to a youtube video that would explain it?

Thank you!

Are you working by dimensions? Simply draw a circle and extrude it to height. Scale the end down or use the draft function.

OR

Draw 2 circles, one inside the other. for example a 5 mm circle inside an 8mm circle. Exit sketching and use the move tool to raise the smaller circle to the height/ length of your dowel. Then use the loft tool to loft one circle to the other.

There are multiple ways to do it.

Hi Rusty,

Here is a short video showing the first method @Oregonerd mentions with the end scaled.

And here is one using the draft angle in the extrusion.

Hi Bob,

Thank you for the videos. I’m using the free version of Shaper3D and I’m not sure I’m doing it right. I draw a circle 1.02 inches in diameter then extrude it 12 inches. Then I click on the extruded face and enter .84. What I’m not sure of is the new diameter. Is it .84 inches or is it 84% of the original circle?

I’m trying to make models for working with pool cues. The standard dimensions of the forearm are 12 inches long with a diameter of 1.02 inches at one end and .84 inches at the other.

Am I doing it right?

Thanks again,

Rusty

Hi Rusty,

If you are using the **scale** tool, it will be percent.

With the details of what you are trying to do, I would use the **loft** tool.  
In this video, I sketched one circle 1.02 diameter, **moved** it with the **copy** option 12 inches, **changed** the diameter to .84 inches, finally used the **loft** tool between the two faces.

Rusty,

Another way to scale: In the cylinder you had extruded that is 1.02 diameter x 12 inches long:

Go to the top face, use the **scale** tool. Use Shapr3D’s calculator to determine the scaling factor: 0.84 / 1.02

Another way, draw a “ half” crossection ( in that case a right-angled trapezoid, the paralel sides are your radius, what you need ) and use rotate around axis tool …
