Hi,

I found this discussion.

https://moi3d.com/forum/lmessages.php?webtag=MOI&msg=8786.1

I am having some issues with this. When i run the code below (in a script passed to the moi.exe in windows), it seems to block the gui and wait for me to do something next? what am i missing?

var factory = moi.command.createFactory( 'circle' );
factory.setInput( 1, moi.vectorMath.createFrontFrame() );
factory.setInput( 3, 10 );
factory.commit();

var linefactory = moi.command.createFactory( 'line' );
linefactory.setInput( 0, moi.vectorMath.createPoint(0,0,0) );
linefactory.setInput( 1, moi.vectorMath.createPoint(10,0,0) );
var linelist = linefactory.calculate();

var pointfactory = moi.command.createFactory( 'point' );
pointfactory.setInput( 0, moi.vectorMath.createPoint(8,0,0) );
var pointlist = pointfactory.calculate();

var trimfactory = moi.command.createFactory( 'trim' );

trimfactory.setInput( 0, linelist );
trimfactory.setInput( 1, pointlist );
trimfactory.setInput( 2, moi.geometryDatabase.createObjectList() );

trimfactory.generateFragments();
trimfactory.finishedPickingFragments();

trimfactory.update();

var objs = trimfactory.getCreatedObjects();
moi.ui.alert( objs.length + ' objects created' );

trimfactory.commit();

Hi Mike,

re:

The gui will be blocked because the call to moi.ui.alert() will show a modal dialog box.

You'll need to dismiss the alert dialog box for it to progress to the end of the script.

cool,

but i did dismiss the alert and the gui is still blocked. its like it is asking for me to select a section of the line to remove with the mouse. But how do i programmatically select line segments to keep or remove?

Hi Mike,

When I run your code on Windows in the latest v5 beta it works just fine. The GUI is responsive after I click through the alert.

Re:

Setting input 2 with an empty objectList like you're doing means that all fragments will be kept.

Re:

What's kept and removed is determined by the contents of the objectList passed to input 2 and whether the factory is running in "keep" mode or "remove" mode.

can you test it in v4? i wonder if i am doing something wrong? see the image? i cant click on the circle, but i can click ui buttons and/or either of the 2 line segments

Hi Mike,

I can click on the circle fine in v4 and in v5.

Is the code that you posted the entirety of your script, or is there other code too? Is there anything going on in the companion .htm file?

It sounds like selection lock is getting set on the circle. That's the typical reason for not being able to click on something.

interesting

that is the whole script i dont have a html file

i am running it with this command

"C:\Program Files\MoI 4.0\MoI.exe" C:\Users\Administrator\Desktop\trimtest.js

excellent,

thanks for your help :)

i needed to add

var objects = gd.getObjects();
objects.unlockSelection();

Hi Mike, clearing selection lock is something that normally happens when a command ends.

When you run a startup script it's not using the "command" mechanism and so you'll have to do some things manually like that.
