(But not between a partial ellipse and a conic, partial ellipse and a parabola, or a parabola and a conic.) I can buy this situation. And now that I check it, you can also now add c2 between a parabola and a spline, and a partial ellipse and a spline. In any case, reseller employee Alin Vargatu pointed out a while back that 2013 SP2, you were suddenly able to add c2 between a conic and a spline. People were making stupid claims, and frankly I think claims that they didn’t understand. I just didn’t see why that wouldn’t work. And if you can’t drive a conic by a spline, you should at least be able to drive a spline by a conic. Whether you can drive a conic by some other element’s curvature, it is undeniable that you can drive a spline by some other element’s curvature. But to say it is mathematically impossible to make something c2 to a conic is simply incorrect.Īlthough the items within sketches are not history based, I’m sure there is some sort of order to getting things done. I recognize all of this and understand the reason why. Making anything c2 to a straight line except a spline doesn’t make any sense. But you can make a spline c2 to a circle. It doesn’t make sense to make two arcs c2 to one another unless they are “co-radial”. I checked 2011, and 2011 does not allow c2 between a partial ellipse and a spline). (Ok, I wrote that about 2013 SP0, but in SP3 you are able to make the c2 relation between partial ellipse and a spline. When you investigate a little, it turns out that ellipses and parabolas are also unable to have anything c2 to them in SolidWorks. I’m not sure that you can drive a conic by the first derivative, although the derivative of second order stuff is easy enough, you might not be able to drive by it, although you’d have to show me why. There is a point of view from which that statement might be correct. There was a discussion on the Conic in the SW forums a while back, where Mark Biasotti, who is usually correct, and usually fair-minded got caught up in saying that it was mathematically impossible to give the conic c2 capabilities. Remember that when 2013 originally released, you were not able to make a spline c2 to a conic. There are two things I want to discuss about SolidWorks 2013.
