My question concerns the demonstration entitled Coupler Curves of a Four-Bar Linkage by Eric Mahieu.
In the enclosed code I have indicated my changes in red and additions in blue.
The green dot represents the point being plotted. The extension value of -1 (minus one) determines
Its position on the coupler linkage. I would like to move the point above (and off) the linkage by
i.e. a Y value of an additional 1 unit.
I suspect that an offset would be required but have been unable to make it work.
How would it be accomplished?
Thank you for your help.
Dave F.
