Sketching a spline

Morning All,

You know me, I only pop in when I have a question to ask. I must stop
doing that...

I'm sketching a spline and it may have either points along the spline
and/or an angle dimension at an end point. If I delete one of these,
sometimes, but not always, the spline stays exactly where it is. I can
tick off the sketch and finish the feature and it's still there in a
shape that is not truly defined by the points and dims of the sketch.
How do I get it to update?

 

I'd suggest, for a spline through a bunch of points, you create the
points first as a point table, which will let you create the spline
through the whole array later. If you also need the ends to be
tangential to something, it gets a bit harder: I suggest you create
short curves estcending from where the ends will be, to define the end
tangency, then use the end vertices of these curves as the beginnings
and ends of the spline. You'll be able to make the spline tangent to
them then, but you'll have to pick the intermediate points one at a
time.

You can 'use edge' this in a feature later.

 

Do you have the intent manager on or off?

 

Intent Manager is on. It's also 2001, we haven't moved to WF yet
because most of our clients haven't.

John, I get your suggestion, I often find I need to create curves thru
points but this was a case where a planar sketched curve was what I
needed. It was actually sketched and projected onto surfaces. I was
hoping there was a way you regen the sketch or force it somehow to
follow its new parameters.

 

Did you try placing sketch points and dimensioning to them? If that
doesn't work, I'm out of ideas.

 

No I didn't, but I don't think it matters how the points in the curve
are constrained. If I delete the point the shape of the curve should
change and it doesn't. Note that it does change when I add a point and
move it around.
