Sweep object - ends have strange crimp

Recommended Posts

Howdy,

 

I'm sweeping a rectangle along a helix and the end and start of the sweep both have this odd kink/crimp occurring.  I've played around with a lot of the setting in both the helix and sweep object with no luck.  Does anyone have a suggestion on how I might fix this?  

 

Thanks for your time!

We need to see the file to be 100% sure what the problem is. Please upload it.

Just increase the subdivision parameter of the Helix to a large amount

  • Thanks for the responses!  Here is a file for you  to look at.  

     

    @Noseman, I tried your approach and it helped but the kink remained, just moved closer to the end so I feel like I'm still missing something.  I also found a cheat by reducing the end growth to 99%.  That seems to do the trick but just curious if that's the best solution.  

     

    Thanks again!

    Sometimes is better increase subdivisions instead of intermediate points of path spline.

    Segmentation is close enough with half of polycount and result looks better. (ofcourse, you could adjust higher segmentation if needed)

    (btw, using quick shading/lines/wireframe mode is easily to adjust everythink since you see directly every change...)

    And to be very fancy, you could even use the Formula Spline for the main spiral shape and a Rail spline, then pipe it through a MoSpline and finally in the Sweep... just saying.

    Just to make it clear, this helix problem is a known issue and not something wrong with your setup.
