Step 1a: Create a rectangle spline. To do so, go to the create tab and click on the shapes button. From there you will see a bunch of options for splines you can make. Modify the rectangle into a trapazoid, by puting an edit spline modifer on it in the modify tab (its in the drop down menu), adjust the points a bit
Step 1b Create a circle spline.
Step 2a: Create loft, this is in the create tab, geometry, compound shape drop down (make sure the circle is still selected BEFORE clicking loft)
Step 2b: click get shape, click on your rectangle/trapazoid thingy
Step 3a: go to modify tab and then to the deformations roll out
Step 3b: Click scale and reduce both points (you'll see to dragable squares, select both at the same time) and scale down the shape
Step 4a: expand the loft + and you will see shape and path, click shape.
Step 4b: click the shape that is on the path (not the original one, the one that is with your strip)
Step 4c: Rotate it a bit so that the phaser angle away from the hull slightly
Step 5: Admire yoru work
