Use the Sweep Arc tool to create an arc with a known center and end points. Tangency is not a factor in the creation of this arc. The arc will become an edge when you pull your sketch into 3D with the Pull tool.
The sketch grid must be visible in the workspace before you can draw.
To draw a swept arc
-
Click
Sweep Arc in the Sketch group. -
Click to set the center of the arc.
You can dimension the point relative to other sketch objects.
-
Click to set the start point and radius of the sweep circle.
You can dimension the chord angle or offset the angular dimension.
-
Click to set the end point of the arc.
Options
The following options are available for every sketch tool:
-
Cartesian dimensions: Select a point in a sketch and then click this option to see Cartesian dimensions from the point. Cartesian dimensions show you the X and Y distances from the point you select. If you don't have a point selected, it shows you the X and Y distances from the origin.
-
Polar dimensions: Select a point in a sketch and then click this option to see Polar dimensions from the point. Polar dimensions show you an angle and a distance from the point you select. If you don't have a point selected, it shows you the angle and distance from the origin.
-
Snap to grid: Select this option turn snapping on or off while sketching. The cursor will snap to the minor grid spacing increment while you sketch. The defaults are 1mm for Metric and 0.125in for Imperial units. See Units options to change the minor grid spacing.
-
Snap to angle: Select this option to turn angle snapping on or off while sketching. The cursor will snap to the angular snap increment while you sketch. The default is 15 degrees. See Snap options to change the angular increment used for snapping.
-
Create layout curves: The sketch curves are created as layout curves. If you move the design to a drawing sheet, with Sketch mode selected you must select the Create layout curves checkbox again in the Sketch Options group of the Options panel in order to create layout curves on the drawing sheet. See Layout Curves.
