drawing in free space ?

[Anonymous]

Getting the hang of fusion. Coming from sketchup software the biggest hurdle is drawing between two objects in free space for me.

My model attached has opposing stair pieces. I want to draw lines and arcs from the center of the opposing circles (circles are blue in picture). The spline that is there now I drew but I did it a poor way and didn't have the control I need. 

I want the line to go straight out from the center of the circle , then curve back and forth and then straight back into the opposing center. In this example the line would be on the horizontal plane. I want it to be a sketch I can edit. Once the line is drawn I would use the pipe command.

With nothing in that space I tried to put a construction plane but didn't work.

That's 3D sketching it's not that easy in fusion yet, the easiest way I find to do it is you pop the view cube on a angle just click on a corner of the view cube (that thing in the top right corner), when you are in that view you can pick up the points on a face. It takes some practise.

You can't at this time as far as I know add dimensions to 3D sketches you have to make sure the body to body distances is correct before you do the 3D sketching.

I dindt find 3d curve in fusion. Please check attached screen cast. May it will help you.

Thanks for the input so far. The easiest solution i found was to draw my shape to the side on a flat plane. Then move the shape in place.

Where this method wouldn't work is creating a waterslide. There the path is curved and isn't on a level plane.
