Drawing elliptical arcs

You can construct an elliptical arc by:

• Center and radii
• Rectangle

Also, you can convert an elliptical arc to a series of arcs.

Notes

• The toolbar buttons for the modes for drawing of elliptical arcs —  and — are visible one at a time on the Objects toolbar. To switch between modes, click the currently visible button and drag to the button you want to use.
• To cancel the current drawing mode, press ESC, or right-click in the graphical area, and then click Cancel Mode on the context menu.
• During drawing or repositioning an elliptical arc, when in the contextual edit bar you enter a value in one of the edit boxes (Primary/Secondary radius, or Angle, or Start/End point while drawing, or Dx/Dy while repositioning), and then move to the next edit box, the scope of the elliptical arc preview is limited according to the specified value. Consider the following example:

If you place the first (center) point of an elliptical arc defined by center and radii, enter a value of 20 mm for Primary radius, and then press TAB to move to the Angle edit box, when you point to define the location of the end point of the Primary radius, you see a preview of the elliptical arc with the 20 degree primary radius. To drag the object preview freely again, in the respective edit box enter 0.00, and then press TAB to move to the next edit box. NOTE: The zero-value rule applies to distance values only. You can use it to define relative Dx and Dy values in all contextual edit bars.
