Hide only seams generator

Does it possible to hide only seams generator automatically? (Select?, script? )
Because if you hide edges, "edges of intersection" after boolean union are hidden too!
Or a special box on the browser?

Or have in the export Mesh options "edges of intersection" visible?

Of course I can select by hand then hide it, but it's painful when you have some numerous objects :)

Hi Pilou,

You could name the seams before you do the array, then hide them via the scene browser.

Cheers

Hi Pilou, it is possible to set up a script that will hide seam edges.

To do that, set up the following as the command on a keyboard shortcut:

script: /* Hide seam edges */ var breps = moi.geometryDatabase.getObjects().getBReps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getSeamEdges().setProperty( 'hidden', true );


> Or have in the export Mesh options "edges of intersection" visible?

Sorry I don't understand this part - what does this have to do with export meshes?

Before your script... (Thanks)
as I had not found a solution I wanted to use the screen export but...
this option is missing! Only edges but not all wires ;) (Hidden lines ?)

Hi Pilou - meshes do not have a single "seam edge" like a closed NURBS surface does.

A NURBS surface is like one larger sheet of paper, and a closed surface like a cylinder has a "seam edge" when the sheet of paper is rolled up like a tube and the opposite edges touch each other.

Polygons on the other hand are like a lot of little fragments, they are not like a big bendable sheet of paper and so they do not have a special seam edge, they only have a bunch of polygon edges.

So that's why there is no seam edge display option in that location, because when you are looking at a mesh there are no seam edges there.

Does that make sense?

Yes I am agree and anderstand, but that will be cool to have render "Hidden line" on the options of export mesh
despit the fact that see drawings polygons as result is the most important part of it :)
I can't have this in the mesh export viewport

Hi Pilou,

Well no, because that does not show you the polygon structure of the data.

The main purpose of the mesh export is to show you the mesh data, not to try and show you the NURBS edges...

When you do mesh export, the thing that you are seeing on the screen is not your NURBS object anymore, it is a polygon object.

Yes for seams from BaseObjects only.
Shortcut: H or ...........
script:var gd = moi.geometryDatabase; var breps = gd.getObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getSeamEdges().setProperty( 'hidden', true );

Bevor

After

see, not everything goes in hidden status (Front right)

that's because it's not a seam edge anymore. Looks like it was a seam edge but you trim away (via boolean) so the remaining part was two distinct pieces of the original sphere. So I think the display is correct...

Hi Eddi, yeah I think Jonah has it described well above.

If you use Edit/Separate on that object, you should see that there are 2 pieces there that you can drag away independent from one another.

A seam edge is when there is the same 1 surface on both sides of the edge.

It is possible for edges to change their configuration after things have been sliced up in booleans like in your case there.
