tog_minusMotion-Law Selector Red-14-2


The Motion-Law Selector is one of the toolbars. It is a drop-down box. See Motion-Laws.

In MD14.1+, the Motion-Law Selector is below the motion graphs.

tog_minusMotion Width Red-14-3




The default Motion-Width = 360.

This is ideal when the motion repeats each cycle of the MMA 0 to 360.


If the Motion-Width ≠ 360, and it should be 360, you MUST use the Segment-Editor to edit Segment-Width parameters.

Edit the Segment-Width of the segments so that the Motion-Width = 360.

tog_minusMotion Name-Tabs Red-14-4


The Motion name-tabs are above the Graph-Area. You can rename each motion.

When you have many Motion Names tabs, you may need to use the left and right, < > , scroll buttons (4a)

See: MotionDesigner > Edit menu > Active Motion Settings > Motion tab.

tog_minusGraph-Area Red-14-5

Motion Graph Area: is where we plot the four important motion-derivatives: Position, Velocity, Acceleration, and Jerk.

You can show, or hide, each motion-derivative. (see View menu)

Motion name-tab: is at the top of the graph. In this image there is only one name, which is the default name.

Selected-Segment : is Red.

Y-axis Units : to the left of the graph of each motion-derivative (P V A J)

X-axis Units : below the graphs

Machine-Speed : below the X-axis and graphs in Red.


Machine-Speed is set in Edit menu > MechDesigner, not in MotionDesigner
