Create curve Tangent to two lines

Hello,

I am trying to make a curve tangent to 2 lines. I am new to grasshopper, been using for about 2-3 weeks. In my included files I have a polyline and 3 curves that I can choose from menu. I then revolve the 2d curves to create 3d solid. My problem is that the 3 curves reference curves in my rhino file. I would like to have the curves created in Grasshopper so I can use the definition in existing or new Rhino without referencing curves.

I have gone through the forms and found a few definitions, but they seem overly complicated for what I need. I have included lines from center of top dome section to use as reference for tangent curve(s).

Thanks in advance … Randy

I guessed that you were using a quarter ellipse for the dome curve. The mesh component is just for a better appearance in Grasshopper (ie. not necessary for baking in Rhino).

Hello Chris,

Thank You, I have to study this a bit. So you split the ellipse using the centre of the top tube as a reference. It is getting my head away from Rhino workflow. I was trying to make a tangent curve instead of thinking to use a quarter of an ellipse. You also broke down the polyline into points and move the points with number sliders, to move with x,y,z … great.

How do you do the titles for the groups?

Thanks again … lots to learn,

Randy

Thank you again, sometimes the simple and obvious things elude us. The definition really helps me understand Grasshopper a bit better.
