Batch STL check - Output Status?

Anonymous — Fri, 15 Oct 2010 14:26:59 GMT

Hi World...

I want to run an STL check on a batch of objects at once and output the results to a txt file.

I am fairly competent with maxscript, but i am not sure how to access the output from the Status box of the STL check modifier... is it possible to interigate this vaulue?

I cant find a reference to it anywhere..Anyone know how?

I am using MAX2010

Sorry for digging up a very old post, but I'm having the same issue... 10 years later.

It's the only place where I find a reference to this problem.

Even the documentation of 3ds Max about modifiers gives no solution :

https://help.autodesk.com/view/3DSMAX/2020/ENU/?guid=GUID-C6B059C5-0A79-43BF-AD26-97305BF4B5D1

And I check different version of the documentation... No solution.

It's basicly the same each year.

I'm using python with MAXScript but if anybody has a solution with C++/MaxPlus I'll take it too

Please help me

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

# The STL_Check Documentation : https://help.autodesk.com/view/3DSMAX/2020/ENU/?guid=GUID-C6B059C5-0A79-43BF-AD26-97305BF4B5D1

#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

Glad to see you found your way!
Thanks for archiving the information.

is it not easier to get open mesh edges as:

(meshop.getOpenEdges obj.mesh).numberset

Yes it is but it's just an example. STL check provides other checks :

In my case, I use it for doubles faces and spikes.

// It was a light chat in Discord that didn't get specific past; STL and wanting to find faces.
I'm sure he could fine tune it.. in fact, I'd be surprised if Scriptspot didn't already have a similar tool.

Hello there 🙂

I bump on this one. I'd need to read the Status of the STL Check, the number of errors if any ... is there any chance for the devs to expose this to MXS, please ?

Thanks in advance !

Regards.
