Re: offset of your polyline is not closed, it looks like that is related to this little dimpled area here: It will also be problematic to do further work like extruding something like this because the fragmentation will inherit to that as well and you'll be working with an object made up of lots of little plane fragments rather than large smooth surface pieces. So it would be good to be working with a smooth curve rather than lots of little line segments. Hi Supagoat, well one problem is your curve isn't smooth, it's a polyline made up of 42 line segments.Īn offset of that will work but it will be even more jagged. You can see that there's a bigger gap between the curves at the front than there is at the top and bottom: Here's a pic of what happens if I try to copy the curve and inset. To complicate things, since it's a DXF import the 'curve' is represented by a bunch of points and lines. What I'm looking for is the ability to scale down a curve, scaling each point 1mm in perpendicular to the tangent of the curve at that point.

The question is how do I produce a loft or extrusion that is consistently 1mm thick all around?įor example, if I try to duplicate the curve of the rib and scale it to extrude the leading edge out of the space between the curves, the scaling doesn't keep the spacing between the points. I ultimately do want to loft from one rib to the next to generate that leading edge skin, but the problem is that I need to get a solid wall - let's say 1mm thick. I use an airfoil generation program to create a bunch of DXF curves for each rib (they get smaller as they get closer to the wing tip).
