Hi, 

Boolean is a feature provided by occ and it only work with objects created by occ (stl are "discrete" objects not occ objects). 
This is explained in the documentation in the part related to the API. 

Regards

BQ_BEGIN

I am a new user of Gmsh. I wanted to use the Julia API to compute the Boolean difference between two models given in two STL files. 

I wasn't able to figure out the commands from the documentation and the api demos. I also tried to use getMass and getCenterOfMass commands but I don't know what the tag of my model is. This is my code. I had to comment out the line with getCenterOfMass. I was wondering if someone can help me. 

Thank you! 

#!/usr/bin/julia 

include ( "/Apps/gmsh-4.3.0-MacOSX-sdk/lib/gmsh.jl" ) 

import .gmsh 

# nice shortcuts 
model = gmsh.model 
factory = model.geo 

# initialize Gmsh 
gmsh. initialize (ARGS) 

# Print messages in terminal 
gmsh.option. setNumber ( "General.Terminal" , 1 ) 

model. add ( "top" ) 

gmsh. merge ( "../models/top.stl" ) 

# model.occ.getCenterOfMass(3, 1) 

# export the mesh ; use explore.py to read and examine the mesh 
gmsh. write ( "test01.stl" ) 

gmsh. finalize ()
