Hi Rob,
Thanks for letting us know about the situation inside SideFX.
Though I can't believe since I've seen many same situation around me, but now I will try to make some scene file (maybe with python script) that can reproduce the problem in stable, constant time.

I use intel Mac Pro, and have same problem through H18~H19.
The program runs perfectly fine under a hour after launch, but soon becomes sluggish.
I was told this setting below when I asked for support once.
It made situation a little better in my case. (though mainly remained)
inside Houdini.env:
I'm using macOS 12.1, but I think situation hasn't changed since 11(BigSur).

I'm not sure if it's related, but feels just like the same here.
There are no specific errors, but it gets slower and slower over time.
Typically after using around 1 hours or so, I won't be able to drag the viewport smoothly.(or even inside the network view)
Only thing that helps is to restart Houdini.
Once when I asked for support about this, I was told to set this inside Houdini.env:
It got a little better than before, but the situation still remained.
It seems to solve some problem inside viewport, not around UI.
I hope SideFX could look into this someday seriously.

I gathered two ways of merging shapes in hip.
Method A is an idea from yone80 (https://twitter.com/yone80).
Thank you for all the help.

Thank you vusta! This is simple and solid.
I've recieved some advices on twitter when using boolean in this situation, so I will share it here later.

Thank you BabaJ for the great example, it teaches me a lot. (I love wrangling)
I didn't know a usage of functions like intersect_all().
Now I'll start dealing with about how to make these methods work in any shapes or numbers of curves…

Thank you ndickson for the great help.
I understood about Hole SOP and the bridge, not to get errors in inner boundary.
And thanks for the long try with NURBS.. didn't know about trim SOP yet, so I'll try dealing with it.
Also will try to avoid NURBS too. All I want is to keep the vector shape as it is.
It is fine using either bezier curves or polygons.

I'm trying to find a procedural way to combine multiple curves in Houdini.
And for the first step, I tried to combine multiple circles as below, but couldn't make it happen..
(image above is done by Adobe Illustrator)
–
Here's a process i've been through.
At firt, I made a simillar state in Houdini. Still not combining.(#01)
Next, I tested combining only two circles. And It worked well.(#02)
And I tried to merge two states above using for-loop. (#01 and #02)
It works like combining curves one by one. Seemed it worked, but after 5 times of iteration, whole curve broke. This is because curvesect SOP's Keep Even/Keep Odd settings need to be changed depending on curves' positions or shapes. And I couldn't control this in any ways…
After a while, I came up with another method.
Which is to convert and combine as polygons first, then convert them again as NURBS.
Even though curves have to be resampled, worked well than the previous way.
(Boolean SOP is used for self-intersections, so I used left input only)
But when iteration comes to the end, center area gets filled with polygon.I tried Hole SOP couldn't resolve this.
If possible, I want to avoid converting/resampling as polygons or VDBs, and keep them as curves during operation.
(so the shapes won't change and keep accuracy)
Curvesect SOP was really nice but couldn't determine EVEN/ODD settings…
Sorry I'm new to Houdini, and my English is poor.
It would be really appreciated if you could give me any advice. Thank you.
