Project body curve

[Anonymous]

I am trying to use a projection of the rocker surface of a surfboard to machine a groove (or channel) in wood. The resulting sketch has several control points. I would like to extend the curve on either end using a spline and then get rid of the control points. Is there a way to do this? When I try to use the generate a machining path, the milling head jumps forward and backward illogically along the segments of path instead of milling a continuous curve from one end to the other.

Try using the Mesh tools to create continuous spline:

1. In your sketch with the projected spline and extensions, create a closed boundary with the projected spline and extensions as one side of the boundary.
2. Extrude this.
3. Save as stl.
4. Import the stl.
5. Create a Mesh Section (Sketch|Mesh|Create Mesh Section).
6. Fit Curves to Mesh Section.

This should give you a curve with only endpoints.

Hi,

I have just tried it with one projected and 2 added splines.
Here is the result:

toolpath 3 d parallel
