Most modeling in Bryce requires boolean operation.   This can be done with a combination of different Bryce primitives, a single one, or with imported objects like dxf or obj.   The following shows how to do this.   However, it shows the roughest form by using boolean to cut out portions of an objects should be noted that this operation can be used to shape an object's edge as well.   By placing a negative primitive (or imported object) at a positive object's edge, the edge can be carved to whatever shape is desired.

First Create a Cylinder.   Select its attributes by clicking the "A" next to it.    Then make it a positive object by clicking "Positive".

Duplicate the cylinder by going to "edit" then select "duplicate".

Make this cylinder slightly smaller in the x and z planes (it may be necessary to make it larger in the y plane so that it is slightly larger (taller) than the original).

Next make this object a negative by selecting "Negative".

Select both cylinders by either dragging a marquee around them with the mouse or holding the "Shift" key and clicking each one.

Select the "G" which groups the two cylinders.

The negative cuts a hole in the positive cylinder.   This results in a tube.

You can create complex boolean objects by then selecting the "A" for the tube object and making it a positive object by selecting positive.

Create another cylinder and position it so that it intersects with the tube.   Make the cylinder negative by selecting the "A" and selecting negative.

Next group the negative cylinder with the positive tube by selecting both objects (shift click both or marquee with mouse) then select the "G" which groups the two objects.   This results in a hole cut in the tube.

Use boolean operations like this to help you create any object you can imagine.

After you have completed reading the above, you should practice a little making basic boolean objects.   After you feel you have a hang of it, you may want to visit the advanced boolean tutorial.
