How to add max dimension between two splines?

Lance Plater Oct 25, 2015 12:30 PM

Hi everyone,

I have created two spline curves that intersect like an oval. Both of them are mirrored over a center construction line.

Yet, I'm having trouble dimensioning the two lines on the max points an their y axis. I would like the distance between them to be 4.2 feet apart, but since they are mirrored, solidworks isn't allowing me to do it. I have tried deleting the mirrored relation, but this hasn't worked because the dimension tool doesn't recognize the maximum distance between the two spline curves from where to start the dimension.

You can create two horizontal construction lines, making them tangent to the spline, and dimension between them, but I don't know that it would always be the maximum distance. I don't work with splines much, but hopefully it will get you started.

  Old post, but yes - mathematically, the distance between two horizontal lines each tangent to the splines will be at the local max/min. This comes from a law in calculus that a local maximum, minimum or inflection point has a slope of 0, i.e. horizontal tangent line.
