LocalToolbar-EditArc

Command:

Geometry menu [or Part Local-Toolbar] > Add Arc

What to do:

1.Edit a Part
2.Click Add Arc - see image to the left.

Then do two 'Drags':

3.Drag in the graphic-area to specify the Arc's start-Point and then its end-Point.

AND ALSO

4.Drag again between the start-Point and end-Point of the Arc to define its radius.

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


The Arc is now in the graphic-area.


There are two ways to add the start-Point and end-Point of the Arc

As you 'mouse-button-down, or mouse-button-up':

Add start-Point or end-Point of the Arc as a 'Free Point'

Later, add constraints and dimensions to position the start-Point and end-Point.

Merge the centre-Point with a different Point

Do this to construct a sketch-path.

Top tip:

Specify the Radius of the Arc before you add Constraints between its centre-Point and a Line or a Point.

You must Drag Two times.

Refer to the image to the left:

1.FIRST DRAG: from 1 to 2 to add the start-Point and end-Point of the Arc, then release you mouse.
2.SECOND DRAG: Position your pointer between the start-Point and end-Point of the Arc, at 3 and Drag towards the apex of the Arc4 as you intend it to be drawn, then release your mouse.

MechDesigner adds the Arc with a centre-Point at the center of the Arc and a start-Point and end-Point at each end of the Arc.
