change color surfaces

[MINIMO4]

hello
I need to change the tangent surfaces only selecting only one surface, I wrote this macro but doesn't work fine, it shows me all surfaces selected but doesen't change the color on the screen!!
someone can help me?
Thanks

Sub CATMain()

Dim InputObjectType(0)
Set Document = CATIA.ActiveDocument
Set Selection = Document.Selection
Dim prtPart As Part
Set prtPart = CATIA.ActiveDocument.Part
Dim oHSF As HybridShapeFactory
Set oHSF = prtPart.HybridShapeFactory

InputObjectType(0) = "Face"
Status = Selection.SelectElement2(InputObjectType, "Select a face", True)
If (Status = "cancel") Then Exit Sub
Set FirstFace = Selection.Item(1).Value
Selection.Clear

Dim newelement1 As HybridShapeExtract
Set newelement1 = oHSF.AddNewExtract(FirstFace)
newelement1.PropagationType = 2
newelement1.ComplementaryExtract = False
newelement1.IsFederated = False

prtPart.UpdateObject newelement1

Selection.Add newelement1


Set visPropertySet1 = Selection.VisProperties
visPropertySet1.SetRealColor 255, 0, 0, 0
Selection3 = Clear


End Sub

you script change the color of a new GSD element HybridShapeExtract. This does not change the solid in any way.

not sure what you want to achieve with

Selection3 = Clear

you need to look at your options to do what you want:

check the B-Rep definition of the extract to find the face of the solid (hard to code, not sure if possible)
or
sew the extract on the solid then color the new solid feature (easiest)
or
get area, Cog of each face (and any other valuable info to identify a face) from the extract and cycle thru the solid to find the same face, then select and change color (the one you really want but might be slow, try to run in batch and see if faster)
​

maybe someone does have a better idea?

I need to change color in a mould ( solid body) to differentiate the matching surfaces to part surfaces without manually select.
I'm not an expert in VB code!!! I'm trying to assemble part of code.

i know that in Core and Cavity you have Face Color Editor, a function that will just do what you need. you select one face, it does propagate in tangency then you pick a color. Check online doc.

Yes! I know that fuction, unfortunately I don't have Core and cavity in my catia!
