Thanks to the 3ds Max discord, someone (EricB_NY [D3V]) gave me the good idea to get around this problem.
The idea is to use the "select faces" option which can select all the faces or edges with problems.
You just have to get the selection with "getFaceSelection" or "getEdgeSelection" with your object in parameter.
Then you just check which faces or edges are selected and it's over.
In Pyhton it look like this (sorry MAXScript user) :
import pymxs
from pymxs import runtime as rt
#obj = the object you want to test
obj = rt.Teapot()
try:
rt.addModifier(obj, rt.STL_Check())
except:
print("Object is not usable with this modifier")
# obj.modifiers[0] -> get the first modifier of the modifier list (the upper one) of the object
# Activate the check
obj.modifiers[0].Check_Now = 1
# Define which check you want to use (here the open edges check)
obj.modifiers[0].Selection_Type = 0
# Define which part of the mesh you want to select (it depends on the check you're doing)
# Here I select the faces
# /!\ The documentation is wrong (for python at least) : "Select_Faces = 1" => select the faces of the mesh and "Select_Faces = 2" => select the edges of the mesh
obj.modifiers[0].Select_Faces = 2
# You might need a pause in your script here depending on the size of your object
# Get all the faces of your object (has boolean)
afterCheckOpenEdges = rt.getEdgeSelection(obj)
cptError = 0 # The number of double faces
for isSelectedEdge in afterCheckOpenEdges : # For each face of your object
if isSelectedEdge : # If the face is selected
cptError +=1 # We increment the number of double faces
if cptError > 0:
print("There are "+str(cptError) +" open edges in the object "+obj.name)
else :
print("No problem here !")
Hoping this will help someone.
If you have any question I'll be gald to answer
