Sure it would! I'll take this but might take a bit of time to do it. |
|
|
No problem take your time! |
|
|
Actually this is pretty hard to do, one needs to calculate perpendicular to bspline edges, and I have no idea about how to do it... I'll leave this for post-0.12 release... |

this might be helpful: http://wiki.inkscape.org/wiki/index.php/SpecFilletChamfer we might eventually implement this into sketcher a long time in the future... but to be honest they have offset in Inkscape but I never like offset tools because they are always produce unreliable results and usually requires manual intervention to correct nodes. |

Thanks for the link, interesting anyway. Actually OCC should be able to produce an offset too, I'll have a look... |

Finally implemented! Was easier than I thought since the Part module can give you perpendicular and tangent points on a curve. But as Luke says it doesn't always give the desired result, since what is offsetted are the control points, and the curvature can change depending on the new distance between the control points. But recalculating the correct curvature is honestly a bit beyond my skills at the moment... I think for now it is ok to leave it that way. Reopen if any issue appear. |

I did make a spline "C" shape and then close it with the c key. I want to offset it, but can't. (1830 git) |
