Hello Houdini Community
I'm migrating from Cinema 4D to Houdini and I'm having some difficulties and need help.
I'm importing igs/IGES 3D geometry into Houdini.
I have two problems.

First problem
I am receiving the error message:

"Warning Use PolyDoctor (Topology Tab) for a more reliable
way of correcting the orientation (winding) of polygons."

I used node clean and PolyDoctor to solve the "widing".
But I don't know which setting is missing as I keep getting this error.
I also noticed that when exporting from Houdini in USD the normals seem to work in Unreal 5.
But if you export in FBX, the geometry is invisible in Unreal.


Second problem
In the viewport I cannot select parts of the geometry.
In "Name Attribute" the parts of the geometry with the name do not appear.
In "3D Connected Geometry" the names of the geometry parts appear.
When I export from Houdini to USD or FBX the geometry is combined into one.
But the correct thing would be for the geometry to be separated into parts like in Cinema 4D, with the names of each part.
I don't know how to solve this problem.

Thanks for helping me.

Houdini Round Decimal Size, Position and Rotation Geometries

Hello. I need help. I need to round geometry size, position and rotation values.

Before:

Example of 3D geometry with non-rounded size:
X 200,134 cm
Y 200,321 cm
Z 200,432 cm

After:

Example of 3D geometry with rounded size:
X 200 cm
Y 200cm
Z 200 cm

or

x 200.1cm
Y 200.3 cm
Z 200.4cm


I need to round the size by controlling the number of decimals, using VEX or Python in Houdini.
When exporting in FBX, USD or ABC, 3D geometry in CAD/3D software appears with rounded size, position and rotation.

The script should work for all geometries of various sizes, position and rotation. Not just the example.

Need help.

I need to round size, rotate and position values of FBX geometries imported into Houdini.

I tried using ChatGPT to create VEX and Python script, but nothing works.

(Center, Min, Max and Size.)

Example FBX geometry size Houdini:



Example FBX geometry size Houdini after export to Cinema 4D:
