Re: Spline - Find outer most point
James,
I don't know of a way for SW to pinpoint the exact point of maximum width. My work around is to put a line or plane on the outside of the spline, then measure from the line or plane to the spline. Note the measured distance and approximate location. Put a point in your sketch at about the right location. Make it coincident to the spline. Measure the distance from the point to the line or plane. Move the point until you reach the minimum value of the measurement. I usually dimension the point from a line perpendicular to the line or plane of measurement.

Re: Spline - Find outer most point
Thank you for the reply Jerry, I appreciate it. You way will certaintly work, and I have tried to go down this route, but its a case of infinitely refining it, getting closer and closer to the real answer, but never getting exactly there, its a shame there doesnt seem a way to do it automatically.

Re: Spline - Find outer most point
James - If I've read this correctly, I'd put a construction line tangent to my spline (so a vertical one for your bowl shape) and measure to that.
Or have I missed something...

Re: Spline - Find outer most point
Yes because since the spline's furthest outer most point isnt a point iself (its between two points), I cant directly measure the point. Rather im trying to measure which part of the spline is the furthest out, and these methods seem to rely on guesswork, i.e keep measureing points alone the line to see which has the greatest distance. I can go close to the final answer but really I want the computer to tell me exactly which is the outer most point of the spline.

Re: Spline - Find outer most point
Hi James - I'll bang on about the tangent line because that doesn't need a point. That's the point...
See attached. Apologies if I'm still not getting it - perhaps you could post an image of what you're doing...

Re: Spline - Find outer most point
Keith is right about finding the max distance from centerline. If you want to find the exact axial and radial location of the tangent point, add a sketch point coincident to the tangent line and also coincident to the spline.
