STEP 2: Use the Drag technique to add the Part to the graphic-area

The start-Point is where you mouse-button-down.

The end-Point is where you mouse-button-up.


Notes on the new Part

Its Part-Outline Red-14-1b is Blue

There is a CAD-LineRed-14-2 from its start-Point to the end-Point

Its XY-AxesRed-14-3 are at the start-Point

The +X-axis is from the start-Point to the end-Point of the CAD-Line.

Save your mechanism


To Add Part

1.'Left Mouse-Button Down' (and keep it down) - to place the start-Point

2....'move your mouse-pointer'

3....'Left Mouse-Button Up' to place the end-Point.


Add Part is NOT a persistent command. Thus:

After you select Add-Part, and before you drag, do not click in the graphic-area. MechDesigner will not add a Part with zero-length.

If you click without dragging to add the drag, the Add Part command becomes de-selected.
