I have two reference points in 3D space. Then I connect them with a straight line using 3D sketch. Simple enough, but when I modify the dimensions of the points the line endpoints do not follow causing me to re-edit the sketch and aligning them again. I can only align them by dragging, no relations show up to make these permanent. Any suggestions?
Do you have Automatic Relations turned on?
If not, the line will snap to the point but not stay with it.
I do have automatic relations turned on, but still same result... At a loss here.
It does not even give me the option of choosing a constraint when I select the endpoint and the point.
Don, are the reference points part of a separate 3D sketch or are they part of the same sketch?
The reference points are in two separate parts and the 3D sketch connecting them is in the assembly.
I've seen this behavior when some parts another level deep in a subassembly in an assembly. If thats the case, are those subassemlies set to flexible or rigid? And are the points part of a helix?
If you're desperate and willing to use a cludgy work-around, you could assemble a "3rd" part that only has that curve. Try a 3D curve the same way. If it still will not update, you could construct a plane through the 2 pts and make a 2D sketch - that may work for either method - in assy, or a separate part. Thankfully is is only a straight line and not a true 3D curve.

I get the same thing. If I make the line from reference point to reference point, it does not update.
If I create a 3D line from vertice to vertice, it will update. A 3D line from a sketch point to a sketch point will also update. Doesn't matter if it's a 3D sketch or 2D sketch in the part, the sketch point still works.
That may be your best workaround. Create a sketch with a sketch point in the part.

Thanks everyone, Dwights sketched points are the only thing that seems to work. I am very surprised that SW can not associate the end of a 3D sketch to a reference point. It is very handy to have when your creating parts on the fly. Hopefully this bug will be fixed in a new release.
Thanks again for all the suggestions,
Don
