Hello.

I want to plot a trajectory into the Mechanics Explorer using the Spline block.

I looked at the Steve Miller example (Four Bar Linkage Optimization in Simscape - File Exchange - MATLAB Central (mathworks.com)) and cannot figure out why it doesn't work.

I have a Matlab variable with the x and y cooordinates called anyOldSpline. Modifying End Conditions has no effect.

The result is one single marker at [0 0] which isn't even part of the spline array.

Can anyone help? Thanks in advance

From what I see, it should be just fine. Normally, your spline should be nx3, but I also tried entering nx2 and still saw it plot properly both in the block dialog box and in the Mechanics Explorer.

Things to try:

Have you tried changing the level of zoom? Perhaps you are too far away to see the line and can only see the markers (spheres)
Is there a solid sphere with a very large radius hiding the spline?
