Hey all! found this one in the old forums Rhino - Rhino - Search Results @pascal your script doesn’t work anymore in V5 64bit; tween curves works - any update to the script so far? would be very handy thanks H! [image]

Hi all, did anyone tested ExtractCenterline plugin on current Rhino 6 relase? I am a power user of this plugin on R5.0 ad i just upgraded to 6. On my experience works only on torus; on cilinder recognize the shape but dont draw any axis, and often crashes. Thanks for your support!

Hello - I’ll make another pass through this thing - I see that it does not make cls for cylinders, at least in V6. It does seem to work on ‘freeform’ and other pipes. If you can post a couple of examples, that will make it easier to troubleshoot. Thanks. -Pascal

Hi All, if anyone can help about running issue, here you can find a sample wich shows the plug-in works well on torus, cones, but non with cylinders. Thanks! extract_centerline_test.3dm (2.0 MB)

@f.corradini I’m checking this now - I see where the problem lies - thanks. @f.corradini fixed for cylinders: ExtractCenterline.py (5.4 KB) @hannesgrebin , @f.corradini the ExtractCenterline script and compiled plug-in (way above) are updated to work better with cylinders. -Pascal

HI Pascal I would like to embed ExtractCenterline.py script in to a toolbar but i am not able to get it to run when i click the icon. I embedded the script in a a new button , the script is closed between parentesis as shown below -_RunPythonScript ( …your script … ) when i click the button th…

In the script above change the last lines from this: if( __name__ == "__main__" ): ExtractCenterline() to this ExtractCenterline() (remove the if name==main line and out-dent the Extract…) This should make it work in a button.

Hi Karki -

The version of that script that is found in this thread doesn’t support Extrusion objects.
