Hi and thanks for looking. I am using Rhino 6 Windows 7 Pro. I am also quite new to Rhino. In the attached drawing, I would like to adjust the seam on the outer closed curve. It was created by joining two arcs into a close curve. I have verified it is a closed curve. In the attempt to use the “Adjust Closed Seam Command”, I am consistently unsuccessful. The center closed curve that is highlighted is a center radius circle. I can select it and adjust the seam on it. I have tried exploding the closed outer curve and re-joining it into a single closed curve. I have deleted it and rebuilt it. I have closed Rhino and re-opened it. I am unable to click “Adjust Closed Seam” command and select the closed curve in order to rebuild it. I am certain that this must be a simple problem to solve, but I can not find the answer. Any assistance would be greatly appreciated. Thanks!Celia Bombe Ring.3dm (40.0 KB)
Can you post a .3dm file with the curves? Files can be uploaded using the vertical arrow icon in the row of icons above where you type your post.
You can only adjust the seam for closed curves, not closed polycurves (made from multiple segments, eg. your two arcs). You’ll have to either re-do the circle from scratch, run SimplifyCrv or rebuild the curve in order to make your polycrv a single, closed curve.
I do not believe that is correct, you should be able to adjust closed polycurve seams as well… your curve looks funky to me though with those 3 red segments pointing to the center (if they are part of your “closed curve”). Do post a file with the curve in question.
Oh, sorry - I didn’t know that! I stand corrected. Well, then we need a file!
Thank you David. I have edited the post and attached the file. As a side note, since I originally posted, I created a completely new file and started over from scratch. This resulted in a curve with a seam I was able to adjust. It puzzles me as to what I must have done to render that curve incapable of this adjustment.
Not a puzzle at all - the curve is not closed. Select it and look in Properties, you will see. Here is a zoom on the open ends - about 0.016 mm apart…
I see! It appeared closed but was not. Thank you for this. Thank you so much. I see the value of using Analyze to root out the problem(s).
