Why does my premesh look different to me boolean objects

[nzapegore]

Hi,
I'm rather new to GroBoto, but still after a few weeks have managed to create this speaker object, but I'm getting a very strange effect when I try to convert my boolean objects ( test_speaker001.jpg ) to a mesh preview ( test_speaker002.jpg ). Could someone help with advice, I thought I was progressing with a useable pipeline from GroBoto - Modo, now I'm not sure this is going to work.

nzapegore,

Could you e-mail the .gbr file with this object to info@braid.com ? We'll find out what's going on there.

Thanks boris, just emailed you the file, I'll look forward to any insights you can gleam from the file...

Just a thought, it looks like you are meshing the object with boolean editing deactivated, which would mesh both the primary and trim object. Keep the boolean editing active and see what you get. If not, then something might be wrong.

EDIT: That should read "toggle booleans". with that off, all of the objects are visible including trim objects

We exchanged private messages with nzapegore back then. I looked at the file and here's what I discovered:


Here I fixed the problem (I hope I left everything in the same state otherwise).

There must be a bug somewhere - what happened is the objects in one of
the boolean clusters, the one with many vertical slabs, lost their
Bool ID. If you right-click on any of these slabs in your old file, in
the info section at the top of the context menu it says Bool ID none,
but there is a boolean role (Primary). It means at some point they had
a valid Bool ID.

I Toggled Booleans off, selected and hid all the other clusters one by
one by choosing Hide Object in the right-click menu, lassoed all the
vertical slabs and the ellipsoid of this cluster with the Bool tool
(which created a new boolean cluster out of them), then right-clicked
on the ellipsoid and gave it the boolean role Inside Body (the Bool
tool gives every object the role of a Primary). And there was one
duplicate slab which I simply deleted.

Do you remember using either Boolean Clusters->Clear All Boolean
Properties or Boolean Roles->Clear Boolean Roles in the right click
menu? One thing these commands should not create is objects with
boolean roles but no Boolean ID. Yet it happened somehow...
