If you prefer, you can select an input type, for example Point input mode, then select the type of object it will be, for instance a Fill. When you complete the outline, and the stitch type is set for Fill, the program knows that you will also want to draw an inclination line to set the angle, so it will automatically put you into that mode as soon as the outline is complete.
Some of you will prefer to first make your artwork as ‘Line’ objects with no stitches present, and then later set the stitch types. This is perfectly acceptable. Simply begin drawing. If there is an object selected, the new object type will switch to ‘Line’.
