Hi rolnxyz, here are some scripts that might help.

First one - grow face selection to one neighboring face that is coplanar with the current face selection:

script: /* Grow face selection to neighboring coplanar faces */ var faces = moi.geometryDatabase.getSelectedObjects().getFaces(); for ( var i = 0; i < faces.length; ++i ) { var f = faces.item(i); var edges = f.getEdges(); for ( var j = 0; j < edges.length; ++j ) { var e = edges.item(j); var faces2 = e.getFacesOfEdge(); for ( var k = 0; k < faces2.length; ++k ) { var f2 = faces2.item(k); if ( f2.id != f.id && f2.isPlanar && f.isPlanar && f.isOnPlane( f2.planarFrame ) ) f2.selected = true; } } }

Second one - grow face selection to all neighboring faces that are coplanar with the current face selection:

script: /* Grow face selection to multiple neighboring coplanar faces */ while ( true ) { var did_one = false; var faces = moi.geometryDatabase.getSelectedObjects().getFaces(); for ( var i = 0; i < faces.length; ++i ) { var f = faces.item(i); var edges = f.getEdges(); for ( var j = 0; j < edges.length; ++j ) { var e = edges.item(j); var faces2 = e.getFacesOfEdge(); for ( var k = 0; k < faces2.length; ++k ) { var f2 = faces2.item(k); if ( f2.id != f.id && f2.isPlanar && f.isPlanar && f.isOnPlane( f2.planarFrame ) ) if ( !f2.selected ) { f2.selected = true; did_one = true; } } } } if ( !did_one ) break; }

That's awesome Michael, thanks for the scripts!

thx you for these !!

Increase selection

script: function es(edg){ var i,f; for (i=0; i<edg.length; i++) {f=edg.item(i).getFacesOfEdge(); f.setProperty('selected',1);}} var so = moi.geometryDatabase.getSelectedObjects(), sf=so.getFaces(), i; for ( i=0; i<sf.length;i++) es(sf.item(i).getEdges()); es(so.getEdges());

Decrease sélection
script: function es(edg){ var i,f; for (i=0; i<edg.length; i++) {f=edg.item(i).getFacesOfEdge(); f.setProperty('selected',0);}} var gd = moi.geometryDatabase; gd.invertSelection(); var so = gd.getSelectedObjects(), sf=so.getFaces(), i; gd.invertSelection(); for ( i=0; i<sf.length;i++) es(sf.item(i).getEdges());
