Pattern based curtain family not aligning to grid

I have a problem getting the geometry in a pattern-based curtain panel to offset consistently from the edge of the adaptive points line. The UV grid is straight when applied to my surface.

When I add the panel family the lines are skewed at the top left corner.

I think there's a problem with the reference point hosted by point 6 in the panel family but I cannot work out what. I've attached the panel family to the post. 

 

The reason I need the panels to remain parallel to the grid is that I want this model to form the basis of a stone schedule for ordering purposes.

 

Any help would be much appreciated.

I am not sure what you are asking about, but I think you are referring to the overlap reported in this AKN Article.

Also, take a look at the attached RFA and see how the nested panel family in it is built differently from yours.

Here's another way: See Family 4 in attached HalfStep-2.rfa

Try this one.  I don't have 2021 so I use 2019 to recreate it.

AARGH!  Everything I just did for the OP was 2022!  I hate it when that happens. Oh well.  

 

BTW: the second one I did was using the void approach as well.  The first one I did was using hosted and offset Ref. Points to Spline through. .

Thanks to you both for your input. Is a void cut always the best way to do this? Will it work on curved panels?

@ToanDN that works great, thank you for this. @barthbradley  thank you too, I'll look at your versions once I install 2022.

When you do, you'll see that mine is much better.  I won't be sticking around for the solution credit though.   My work is done here. I'm off to save the planet now.

In a general sense, I wouldn't be claiming that using a void is the best way, or even a better way than other approaches.  In your particular family, it is faster to sweep a profile based on your parameters along the path defined in the template than adding more points, hosting and constraining them properly.

@ToanDN: Do you have 2022?  Just curious to know.

You got my hopes up there for a minute. But alas, the "two-inch overlap" is still with us in 2022.

Well not on my end look closer at the previous post

Well, at first blush, I must admit, it does look pretty good.  Post your file.

I'm not quite sure we are on the same page here, @ToanDN, but yours as the "two-inch overlap" as well.  Or, am I missing something?

No.  You are correct.
