Merry Christmas and Happy New 2010.

Step 3

In this step we are creating the third decoration. This one is pretty easy as well.

So, first lets start with one help line. Using Line command’s option BothSides we will create a line from origin (0,0) 17 units long in each direction making it 34 units long in total. But you will need to input 17.

Now, using InterpCrv command we will create a curve from both ends of this line, and 5units high on the y axis: (you might want to turn on the End OSnap option)

Now, using Revolve command we will create a surface out of this curve:

Next we need to create holes in this surface. We will do this by creating another Ellipsoid and this time we will start creating it from the Top viewport as well, and make its first two dimensions 7 units long,and for the third one we will use 5 units.

Move it down from top viewport by 8 units, and Mirror it using Mirror command over x axis:

Using BooleanDifference make holes:

Fillet the two edges with FilletEdge command and use 0.2 units as radius:

Now, using Rotate command we need to rotate our object 90 degrees and copy our wire tip again from previous decoration models:

Simply move either wire or object so it looks like on the image below:

Using Box command, we will create a box which we will be using to cut the tip of the decoration object. For the cutting we will be using BooleanDifference command:
