The user draws to lines, which are crossed. When he point the end of second section/line, I have to draw an arc, and to sho the angle between them.
Now I draw an angle with lines, which overlap the user lines, but it does not look well and is difficult to modify, when user moves section ends.
I would like just to draw arc, but I do not know, how to add an arc (without lines) as a layer. |

Hi
Yes, you could do it that way. Please see the custom draw demo:
Demos\LayerEditing\Layers_CustomDraw\LayersDraw.dpr
You can draw an arc using a TIECanvas with:
procedure TIECanvas.Arc(X1, Y1, X2, Y2, X3, Y3, X4, Y4: Integer);

Thank you for response. Is there any way to draw it manually? For example I add empty Layer and then I DrawArc in OnDrawLayer event or something like this? |

Hi
Unfortunately arc's are not yet supported, but they are on the to-do list.
