    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi guys, in the past weeks I've further finalized the dimensions and performed some 3D measurements on actual KTM channels. I'm now drawing my own cylinder and modelling the channels so I think now is the right time to check with you guys whether I'm drawing it in the correct way. Currently I'm...

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi Toost, Thanks for the last example. The last weeks I have been busy implementing the tips you both gave and I think I'm getting the picture clear for myself on how to draw the channel exactly as I desire it. I have made silicone molds from a cylinder which is a good basis for my purpose...

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi Toost, John, The scandata is the ideal example for me but I can't implement it directly due to different strokes (54 for the scan, 40 for my application) and different bores (54 for the scan, 47.6 for my application). Therefore I have to scale the window heights on the bore and I can only...

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Yes I will, I'll come back to you tomorrow after I had a good look at it :).

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi John, Thanks for the quick response, I'm very grateful for the help you are providing! I accidently left my laptop at work today so I can't open your modified part this evening, but I can comment on your BTW; I didn't feel comfortable with the middle profile to define my swept but I saw no...

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi all, Today I looked through the help function and I tried my best (as shown in the attachment) to design a channel as good as possible. The result already looks more like my desired result but I still can't use the law function, due to the fact that "Angular Law is available only for sweeps...

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Thank you for the response John :). Is there perhaps an example in cast that you know of which explains using a law in sweep? I can't access cast from home right now so I can't check it but I'm really curious and I would love to be able to model this myself. Thanks, Peter

    How to draw a "twisted" spline in NX 9.0 or 8.5

    And hereby a second picture just to make it clear. These guys used solidworks but I think it should be possible with NX as well?http://files.engineering.com/getfile.aspx?folder=2b73c9d2-3149-47f3-8e5f-8e52f818cd82&file=speed3.jpg

    How to draw a "twisted" spline in NX 9.0 or 8.5

    Hi Guys, Let me introduce myself shortly first; I'm an Dutch mechanical engineer which loves to tinker on two-stroke engines in his spare time and recently I came up with the idea to develop my own cilinder. I've got all the tools / connections such as a lathe, mill, a foundry which is willing...
