Hello,
I try to create a node for the node editor with the offset factory, but I can't figure out what I should put in input 2?
The code isn't finished and should work for curves in a first step (breps later).
Could someone explain the orientation and position of the frame?
// offset
function offset()
{
this.addInput("Object", "objectlist");
this.addInput("Frame", "pointarray");
this.addInput("Distance", "numarray");
this.addOutput("Object", "objectlist");
this.properties = {mode: ["Long", "Long", "Short"], dist:[1],dir:["Normal","Normal","Flipped","Both"]};
}

offset.title = " offset";
offset.desc = " offset";

offset.prototype.onExecute = function ()
{
var data = this.processInOut(this.properties.mode[0], this.multiProcess,null, null, this.properties.dist, this.properties.dir);
this.properties.dist = data.inputs[2];

this.setOutputData(0, data.outputs[0]);

}

offset.prototype.multiProcess = function (obj, frame, dist, dir)
{

var out = [];
//sharp
out[0] = factory('offset', obj, dist, frame ,'sharp',true, null,false,false);
/* var ofFac = moi.command.createFactory('offset');
ofFac.setInput(0, obj);
ofFac.setInput(1, dist);
ofFac.setInput(2, frame);
ofFac.setInput(3, 'sharp');
ofFac.setInput(4, true);
ofFac.setInput(6, false);
ofFac.setInput(7, false);
out[0]=ofFac.calculate();
ofFac.cancel();*/

return out;
}

LiteGraph.registerNodeType("Construct2/ offset", offset);


Thanks in advance!

The Offset.js file seems to use commonplane and pointpicker to get the Frame...
?

Hello Brian,
yep! I saw it also, but what is the meaning of that :-) I didn't find other docs. Maybe I should use a workaround with a sweep factory!?
I don't know ...
Have a nice day

Hello,
problem solved - everything works fine:-)

Hi Karsten, sounds like you're all set up but just in case the inputs to the offset factory are like this:

0: FactoryInput_ObjectList, "Objects" // Objects to offset.
1: FactoryInput_Double, "Distance" // Offset distance.
2: FactoryInput_CoordinateFrame, "Offset pt" // Offset through point or which-side point for curve offset.
3: FactoryInput_String, "Corner type" // Corner type "sharp" or "round", for curve offset.
4: FactoryInput_Bool, "Trim" // True = trim curve results.
5: FactoryInput_Bool, "Flip" // True = flip solid offset side.
6: FactoryInput_Bool, "Both sides" // True = offset curves to both sides.
7: FactoryInput_Bool, "Cap ends" // True = add line segment between ends of open offset curves.

Hello Michael.

thanks for the reply!
Important for me was this:
var pln=ofFac.getCurvePlane();
ofFac.setInput(1, dist);
ofFac.setInput(2, pln);

I've displayed the pln frame in the nodeeditor and now I know what to do, to filp the side of the offset (I don't have a pointpicker here!).

Have a nice day
Karsten
