My friend Karen was trying to figure out how to use a panto that is two rows that are mirrored. While she was using a commercial pattern, it works the same as using a semi circle to create egg and dart.
Quilt Path comes with a semi circle, so now I can have quilt path do one of my very favorite sashings!
From the Home screen, under Design & Create, click on Pattern. This will take you into PatternCAD.
Click the Select Pattern Button. Click on the Continuous Line button. Choose SemiCircle.
Once the semicircle is on your screen, click on the Draw button under Mirror and then click on the Horizontal button
You now have the image you are looking for, a single egg and dart. To get rid of the horizontal line click on Apply Mirror.
Now all you need to do is save your new design. If you did not apply the mirror you will get a message asking you if you want to save the reflection. You just say yes and it will apply the mirror at that time.
