For complex shapes, sometimes it’s easier to sketch the initial shape with a traditional Spline, convert it to a Style Spline, and then fully constrain it with relations and dimensions.  Please explore this technique and let me know how you like it in the comments below.\u003C\u002Fp>\u003C!-- \u002Fwp:paragraph -->","2018-09-10T09:55:08",{"node":34,"__typename":44},{"nicename":35,"description":36,"slug":35,"name":37,"firstName":38,"lastName":39,"avatar":40,"__typename":43},"jordantadic","Jordan has been serving the SOLIDWORKS community for over 10 years.
