smooth curve - could be applied to any closed curve
select 2 points, select part that u wanna cut, adjust curvature

If you want a smooth curve it's kind of strange to start out with a rectangle instead of just drawing a smooth curve right from the start.

But you can do something similar in Moi if you want, draw in a line, use the Trim command cut away the part you don't want, then use Edit > Add pt to add a point to the middle of the line and turn on edit points and adjust the point.

Adding in a special tool to do that would not be good, that's exactly how bloat happens.

I do have some ideas for having different draw modes to make draw commands intersect and cut away pieces without needing to do a separate Trim step.

mb it was such a script made, polyline with offset, wanna combine in polyline option (pressing O)

PolyCut updated, solved random issues
select one curve/solid - run the script
will change perspective to isometric
1. for solids/breps -> works in all views
2. curves - only in orto (moi doesn't perform booleans of random plane/frame curves)
right click to close the curve, or u can close manually

select last created is not working after deleting any object

Hi Tudor,

re:
> select last created is not working after deleting any object

Yes that's normal. Select last created (by using moi.geometryDatabase.selectLastCreated();) selects whatever geometry was created by the last run command.

When you run the Delete command, that becomes the last run command and so then select last created will select whatever was created by the Delete command which will be nothing if you deleted an entire object, but other cases like the result of deleting only some faces or control points will be selected.

any tips how to use shrink trimmed surface, or where it can be used ?

Hi Tudor, if you start with a complex surface and then boolean or trim away a large portion of it:






the original full surface is still there as the "underlying surface":




If you apply ShrinkTrimmedSrf to this, it will shrink down the underlying surface and cut out areas outside of the trim curve boundaries:



This can reduce surface complexity in cases like this and sometimes there can be problematic things like self intersections in other areas of the underlying surface that could interfere with some kinds of calculations.

Usually it is good to keep the full original surfaces because it makes repair operations by untrimming easier but if it's a very complex surface it can carry a lot of data size.

problems with export as fbx/obj
fillets are not native

Hi Tudor, it looks like maybe the object is inside-out. Try selecting it, then run Edit > Separate followed by Edit > Join. That seems to get its orientation set up ok.

Also your object is at a very small scale of only 0.02 units across. Try scaling it up by 100 times before meshing it, that will avoid some points from getting merged together.

constant fillet fails on curves and not on surfaces, weird

Hi Tudor,

re:
> constant fillet fails on curves and not on surfaces, weird

Prior to v4, constant radius fillet was not available for curves at all, as of v4 it works on line segments:

could be implemented in next version ?

Hi Tudor,

re:

Sorry, no probably not, it's not supported by the geometry library currently.

can't find script for "select similar edge length"

Hi Tudor,

re:
> can't find script for "select similar edge length"

Is it one in this thread? :
http://moi3d.com/forum/lmessages.php?webtag=MOI&msg=8905.1

not quite that i'm searching for
there's a filter for curves biggest, smallest, or min/max , but I'm searching for edges
example - extrude taped, select one side edge of taped - run the script -> fillet/chamfer
or draw a rectangle, extrude by x amount, select 1 edge of height - run the script, or select the edge of original rectangle run the script

i've forgot lots of moi's scripting
select desired edge
moi.geometryDatabase.getSelectedObjects().getEdges().item(0).getLength(); get's edge selection length
get parent object(want only for current selection, in case there are duplicates of same object), get edges, loop through edges, if there's similar length - select

or if i Have a selected edge how can i get object numEdges count for the loop
by my understanding it should be ~ moi.geometryDatabase.getSelectedObjects().getTopLevelObjects().item(0).getEdges().numEdges
moi.geometryDatabase.getSelectedObjects() -> selected
.getTopLevelObjects() -> object itself
.item(0) - object nr
.getEdges() - all the edges
.numEdges - count edges
that doesn't work

Hi Tudor, the problem in your script there is this part:

> .getTopLevelObjects() -> object itself

All the " getXXXXX()" methods on an object list do are filtering mechanisms, they make a new list that only contains the given types that are already present in the current list.

So if you had an object list with 2 objects in it, an edge and a brep, when you call getTopLevelObjects() it would return a list with just the brep in it, that's the only top level object currently in the list.

If you have an object list with just one edge in it, calling getTopLevelObjects() on it will return an empty list because there are no top level objects directly in the list currently.

You need to instead do something like this:

var objs = moi.geometryDatabase.getSelectedObjects(); if ( objs.numEdges == 1 ) { var edge = objs.item(0); var edges = edge.getParentBRep().getEdges(); moi.ui.alert( edges.length); }

So get the edge object, call getParentBRep() on it to get the parent brep, then call getEdges() on that.

thanks !

/* select similar length edge*/
var edgeSelected = moi.geometryDatabase.getSelectedObjects().getEdges().item(0).getLength();
var objs = moi.geometryDatabase.getSelectedObjects();
var tollerance = 1000;
if ( objs.numEdges == 1 ) {
var edge = objs.item(0);
var edgeL = objs.item(0).getLength();
var min = edgeL - edgeL/tollerance;
var max = edgeL + edgeL/tollerance;
var edges = edge.getParentBRep().getEdges();
for ( var i = 0; i < edges.length; ++i ) {
var edgeLoopL = edges.item(i).getLength();
if ( edgeLoopL> min && edgeLoopL< max)
edges.item(i).selected = true;
}
}
