I need to know if posible to avoid certain numbers when defining the Range in a float expresion parameter.
The float Range goes from 0 to 1.

I need to avoid the following numbers:
0
0,25
0,5
0,75
1

In some expresions, using the symbols ^ or ! negates de selection.
¿Is there a way to use in Range selecction??
Thanks.

something like this, really stupid solution, i know.
Have a look at the translate expression…

Why would you avoid those numbers?

if (ch("testx")==0||ch("testx")==0.25||ch("testx")==0.5||ch("testx")==0.75||ch("testx")==1,ch("testx")+0.001,ch("testx"))
Thanks again Mathias,
after using Refine in a quad_grid + Copy to point , the corners breaks the simulation. I solved it using with the Resample node and deleting the corners (with Sort to point (0,0,0) + Delete 0,1,2,3 points).

The image below is for place a Door in a wall.
¿Is there any trick or best way to do??
Im very newbie.

in this case you can check corner angles and skip them.

Something like this?
You can maybe break it for each wall
and add some controls for “which wall”
then resample to half door width, delete each first/last point
and then use the carve to move the door…

The photo I uploaded? Yes of course you can.

Both examples you uploaded are fantastic.
For the first one is dificult to understand the relation between “Resample>segments” and “Marker>modulo” , changing those numbers alters the number and positions of the doors.. but dificult to control them.

The second one has the issue with the Bool, it breaks also the corners making dificult to place a door after in such place.

Yes, I know, that's what I said:
Use a Carve SOP with “Breakpoints” on the “Wall Curve”
Then put it in an HDA with a select slider for the “Wall”.
On the Segments add A: a resample with proper values, then delete
first/last point.

Simple example attached, yes I know, it needs some more love ;-)

easiest way is to add Measure>Curvature.
Then Delete, Points, Delete by Expression: @curvature>5 (or whatever you see fit)
Points in a straight line would naturally have curvature = 0 so won't be deleted

Thanks Matthias_k & Vusta.
The examples you both posted here solved my problem.
The example “simple_hole_in_the_wall-1.hip” posted by Mathias with the ability to place the door in one particular wall + position it, … priceless for me!. Thanks very much Matthias , I appreciate your help.
