#Newbie : How to add spline control points? ?

francisco_marshall

Hi Onshape community, please bear with me I just bought a 3D printer and I am learning how to use a CAD...
So my first question (probably far more will come in the future) : Spline editing.
I have a sketch and a spline ... I want to add more control points to my curve, but when I add one, it doesn't show me a white dot to modify the curve... what am I doing wrong?
Thank you! 
Best, Frano

Hi @francisco_marshall - those are just points on the spline, not control points, so there are no tangency handles associated with them. If you need tangency handles at those points, you will have to create multiple end-to-end splines (with tangency between them).

Thanks Neil, so to check if I understood; a spline segment only offers 2 tangency handles. I would have to "overlap" two end-points in order to create a larger segment with multple handles?

That is correct - not ideal I know.
