Using the Lathe Tool

In this tutorial we will describe how to use the Lathe Tool.

This tutorial assumes familiarity with 3D Canvas and that the 3D Canvas Basics tutorial has been completed.

bulletDrag and drop a "Lathe Tool" object on to your scene.

 

 

bulletClick on the grid near the top. This will add what is called a "control point". This point is the beginning point of your lathe profile path. The first point of a path is always colored green so it is easy to find.

Move this point so that its position is exactly on X=0. When you drag the point its position is indicated on the left side of the status bar. The first number is the X position.

 

bulletClick on the locations indicated by white control points. The profile path is by default a curve that follows the control points.

 

bulletClick on the final control point from the previous step. It turned blue. This indicates a "fixed" location. A fixed location is a hard edge along the profile.

Click below this point as shown. Note that we now have a hard edge.

 

bulletChange the Rotate field to .25. This indicates that we want only want a 25% sub-section.

 

bulletIf you rotate the preview you will notice that the object created is not solid.

 

bulletIn order to make a partial object solid, we have to close the lathe profile. Note that this is not necessary if creating a full object.

Add the control points indicated. Make sure that the final point is exactly on X=0.

 

 

bulletThe final step in closing a profile is to click on the initial green control point.

Once you have closed the profile, click the close box. Answer "Yes" to updating the object in your document.

 

 

bulletCopy and paste the object on to the scene to make a duplicate.

 

 

bulletFlip the new object along the Z axis as shown using the Flip operation. You can change the axis that the Flip operation uses by selecting an object and then right clicking on the Flip operation.

 

 

bulletMove the objects so they are about two units apart.

Right-click on one of the objects, select Properties and determine its Group Position.

Right-click on the second object, select Properties and enter a value for X and Y that match the first object's position.

We are going to bridge the two objects so we need to be sure that the only difference between their position is along the Z axis.

 

bulletMerge the two objects by selecting one object, clicking , and then clicking on the other.

Select the two faces indicated.

 

bulletClick the Bridge operation to bridge the two objects.

If you find that the faces will not bridge due to an unequal number of points, applying an Optimize operation will likely resolve it.

The flat side of our object is now made up of multiple faces. Merge the faces as described previously.

 

 

bulletCopy and paste the object.

Flip the copy along the X axis.

Position the two objects as shown, taking care that their Y and Z positions are the same.

Merge the two objects.

Select the two opposing faces and apply a Bridge operation.

 

bulletOur completed object: an architectural feature, butter dish, or perhaps just an interesting looking object.
