Arc (Center and Radii Points)

General

• You can sketch an arc by clicking a center point and two radius points.
• The first radius point defines the starting point and radius of the arc.
• If you click the location of the center point of the arc from the origin of the sketch, the end point of a line, or the center point of another circle, the program automatically adds a concentricity constraint to the circle with the aforementioned element.
• If you do not select a work plane, the arc is drawn on the drawing plane, the plane that is currently facing you.

Sketch an arc in a 3D sketch

1. Select the function 3D sketch | Lines | Arc with Center and Radii Points or
   • select the context-sensitive function Arc Center+2 Rad.Pnts.
2. If necessary, select the line properties, under Sketch | Style
3. If necessary, select Workplane to sketch a circle on an auxiliary plane.
   • Add a Sketch Plane in the 3d Sketch.
   • Select a Sketch Plane as a Work Plane in a 3D Sketch.
4. Select the center point of the arc.
5. Select the arc’s first radius point.
6. Select the direction angle of the second radius point of the arc.
7. Repeat steps 2 to 6 to continue sketching arcs.
8. Stop sketching arcs
   • Select another function or
