Add Circle

Toolbar-SE-AddCircle

Toolbar:

Geometry toolbar

Menu:

Add menu > Geometry sub-menu> > Add Circle

What to do:
1.Edit a Part
2.Click Geometry toolbar > Add Circle
3.Drag in the graphic-area to specify the Circle's centre-Point and then its radius.

'Drag': mouse-button-down [centre-Point], move your mouse-pointer, mouse-button-up [radius].

The Circle is now in the graphic-area.

Free-Points and Merged-Points

Add the centre-Point as a:

Free-Point

Do these steps for a layout sketch:

1.Add the Circle so that its centre-Point is free of other sketch-elements.
2.Add a Dimension to define its radius
3.Add constraints to locate the centre-Point

If necessary, you can delete constraints and dimensions.

Merge-Point

We do not often recommend you merge the centre-Point of a circle with a different Point.

See: Hover+Drag , merge-points.

Notes:

A Circle is a Sketch-Loop.

A Circle is the most basic shape of a Cam-Follower.

Top tip:

Add the Dimension before you add other constraints. The centre-Point may collapse to zero radius if you add a constraint before you add a dimension.
