stitch_surfs will create a shell body, not a volume body. When you use make_Lump, it makes a volume body if the surfaces are manifold.<br><br>Can you give an example of the failure case and the situation that you want to solve? I want to understand your request better before going further.<br>

<div>I notice CGM will create a volume no matter if the surfaces are manifold or
not.</div>
<div> </div>
<div>Does CGM have a function to separate this non-manifold volume to several
manifold volumes?</div>
<div> </div>
<div>BTW : stitch_surfs doesn’t work sometimes. Does CGM have a function to set
the tolerance for it?</div>

CGM doesn't have this function. However, if you provide manifold surfaces, CGM
can stitch them together to create a volume, stitch_surfs is the
function.<br><br>Jane<br><br>

<div>Hi Gurus,</div>
<div> </div>
<div>I’d like to know if CGM have a function which extract closed volumes (
closed faces, not contained each other ) from nonmanifold faces model.</div>
<div> </div>
<div>Thanks,</div>
