Warning Missing curve

[vandevelde.theo]

Hi,

New to F360 I experience a strange warning that I cannot resolve.

I created an intersection curve from two splines.

Did other changes, but did not use the intersection curve in my design, saved the file. Next day reopen the file, edit the sketch and delete the intersection curve, deleted one of the splines, finished sketch.

The intersection curve is nowhere used in the model anymore (pretty sure, I deleted all the work done after creating it). Now it shows a warning 'Curve is missing' (see screenshot), where the deleted spline is shown red. And the warning 'the model is using cached geometry to solve. But there is nothing to solve.... The geometry is not used anymore.

I use a lot of splines and intersection curves in my design, all went OK until I deleted this one.

How do I get rid of this warning?

Thanks for reply.
