When you add a Plane to a Line, and you edit the position of the Line with the Part-Editor or with a Dimension in a Design Set the Plane does not move to the new positon of the Line.

To get the Plane to move, you must edit the Plane in the Plane dialog, change an angle say, and then close the Plane dialog

So it is an update thing.

Incorrect initial startup of the Belt Controlling Target dimension which was outside the bounds of the Minimum Maximum Values.

This is a reminder to me to check new behavior.

I gave an example of the Polyfit FB being used  - it gave VERY short segments which were not really needed and impossible to see in the motion plot.

This is a reminder to me that I need to check new behavior.

16.1.114 Corrected some time ago

The Colour of the Graph Value Readout below the Graphs in a Graph FB plot returns to the Light-Blue after I have changed the Plot to a sharper colour, to contrast with the white of the graph background.

I have yet to check the 'correction in the new Release therefore reporting it here as a reminder to myself.

When you add a Gear-Pair, the background sketch and part-outlines turn on - which is most often inconvenient when you come to select the Dimension in the PArt-Editor.

However, if you really do need to turn them on, eg when adding Bevel Gears, then turn off the background sketches after Add Gear-Pair command is complete.

By the way, the term now (as is given in the Help and the Menus, for the 'other background stuff' is 'other kinematic and sketch elements'.

The read-only parameter in the Rack Pinion dialog should be mm/deg, or you should change the reported result to deg/mm to reflect the units you give.
