I have put it into the attribute wrangle node and it works like a charm. Thank you very much.

Is it possible to group points based on incoming edges? I would like to delete points which have specifically only two incoming edges.
I did a boolean shatter operation with two spheres. Then deleted ainsideb and binsidea group. Now I would like to clean the mesh a little.
Thank you.

What does Cut Boundary Points in Edge Cusp node do? It isn't mentioned in documentation and it does not seem to do anything.

I tried to use the $N variable in the Group Create node (in Base Group section) to put the last point of a curve into a group but it seems to be ignored. Am I doing something wrong?

Awesome, it works now. Thank you.
One more question - the connection to the handle is broken. Which is probably logical, because as you stated the “Rotation” parameters are driving the Direction parameters which are connected to the handle parameters.
Is it possible to have the handle connected to the “Rotation” parameters?
So whenever I move the handle it updates the “Rotation” parameters and whenever I change the “Rotation” parameters it updates the handle as well?

Thank you guys for your response.

Thank you but I am clearly doing something wrong. My Houdini freezes when I add the second chunk of code and change expression language to python. Can you please debug with me?
1. Through the edit parameter interface I add a new parameter to the knife node - direction vector (I also tried duplicating the “Direction” parameter)
2. I change the name to “r” and change the label to “Rotation”
3. Click apply and accept
4. I copy and paste the first chunk of your code into the first field and press enter.
5. Right click -> expression -> change language to python
6. Copy and paste the second chunk of your code into the second field and press enter.

I would like to add a new parameter to the knife node. Let's call it rotation. It would be the same as direction parameter (which is a vector) but it would be displayed in rotation degrees. So vector (1,0,0) would be something like (90,0,0).
And also if I would change values in one parameter (for example direction) it would update the information in the second parameter (rotation). So I could use whichever one I want.
Something like this. Any way to do it?
Another option would be to have a set of two buttons - one would switch the display of direction values to vector units and the other one to degrees. Point is to be able to choose between these two units.

Thank you! Exactly what I was hoping for. Works perfectly.
arctor
Thank you, also tried this solution but the problem was once I pressed the button it somehow broke the connection to the handle.

Hello
I would like to add a button to knife tool which would set the direction to a specified vector let's say 1,0,0
Is there any way to do it?
Not being good at this I just tried to add “set dirx=1” as a callback script to set at least one component of this vector but with no succes

I absolutely got my answer for what I asked. Thank you for the tips guys. But I just realized I have phrased it all wrong. My bad. What I had in mind.
Can you select these polygons with one click?
You just click once on one primitive and the selection continues until it hits a certain angle treshold. In this example it could be anything from 0 up to 89.999.. I know I could do it manually and there are great valid ways to do it. But applications could get more complex, this is just to demonstrate what I am looking for.
This is the feature I am looking for.

Sadly, my programming skills are pretty low. Maybe in the future. But thanks for the tip!

OK, I made and RFE for this feature. So fingers crossed.

yes you are right, Spread Angle affects the selection. But as Konstantin Magnus says - I was thinking of something more like a contiguous selection which would stop whenever it encounters a certain treshold.

By Angle
When on, selecting a polygon also selects neighboring polygons based on the numeric Angle setting to the right of the checkbox. This value determines the maximum angle between neighboring polygons to select. Available only at the Polygon sub-object level.
For example, if you click a side of a box and the Angle value is less than 90.0, only that side is selected, because all sides are at 90-degree angles to each other. But if the Angle value is 90.0 or greater, all sides of the box are selected. This function speeds up selection of contiguous areas made up of polygons that are at similar angles to one another. You can select coplanar polygons with a single click at any Angle value.

Awesome, got it. Thank you.
But is there any change of getting something like 3Ds Max or Maya like select by angle?
This kind of works but not like I was hoping for. Trouble is:
1. you have to figure out the vector of the primitive (or whatever you are selecting)
2. it selects all primitives facing this vector and doesn't stop at angle treshold
I mean I see a way you could get around this but it starts to loose its efficiency.

In my case this grid bug seems to appear when bevel is so big that some vertices get merged
Benjamin Lemoine
Nice workaround for this case. Tried and worked for me too
bardia
Great news! Thank you.
