Can anyone please tell me what does yellow line in sketcher signify. I use line command and the line I draw is shown in yellow color instead of default color. Why is it so?
A yellow line or curve in Sketcher usually means that the geometry is projected or intersected from 3D. I've never seen any that was created interactively.
The yellow colour means that the element is associative with something outside the sketch. Like catiajim says, when you do a projection, but a projection is not necessary associative and then it will be white.
