junehe Posted January 21, 2015 Posted January 21, 2015 Hey, I have one vertex not smooth on my drawing. How can I change its tangency? It also shows a "+" sign near it, which I don't know what it means. I attached the drawing here for your reference. Thank you so much!!! vertex problem.dwg Quote
Dana W Posted January 22, 2015 Posted January 22, 2015 There is a blue grip under the white cross. Click it (or any other of the grips) and slide it around until it looks good. You can also click the blue arrow, to change between "Fit" and "Control Vertices". Each type gives you a different kind of adjustment. Quote
nestly Posted January 22, 2015 Posted January 22, 2015 "Open" it with the Properties Palette, then "Close" it again. Quote
Bogbadbob658 Posted January 22, 2015 Posted January 22, 2015 When you created the spline it appears you snapped the last point to the first point therefore it's not a closed spline which is why it's not smooth. If you want it be smooth then use 'Close' at the end to close the spline. Use 'splinedit' to close and edit it. Quote
Dana W Posted January 22, 2015 Posted January 22, 2015 Both of those above methods result in there still being reverse curve bump, although a tangent bump. Based on the asymmetrical freehand appearance of the rest of the shape in the drawing, smooshing around the grips a little will get you to a point where it will "look" symmetrical within the parameters of its freehand nature. Of course, closing the spline does need to be done, unless there is a reason not to do it. Quote
nestly Posted January 22, 2015 Posted January 22, 2015 OP did not specify whether there should or should not be a "bump" but they did specify tangency. Since it's impossible to "free-hand" tangency, the solution is still to let AutoCAD "close" the spline even if additonal editing is required to obtain the intended result. (ie edit/delete vertices) Also, AFAIK, the "+" is just to indicate where the spline begins. Quote
Dana W Posted January 22, 2015 Posted January 22, 2015 Yeah, my intent was to cover that in the changing of the control display from control vert's to fit and back again, but I was not very clear in how I presented it. If one would slide the bad vertex a little closer to tangent, the bump almost goes away when changing the display to Fit, then back to Control Vert. If one does not care about the bump, then don't move anything. Tangency magically occurs in the "Fit". If one wants it closed, then do so, if not, leave it open. Quote
