I'm using OS X and I copy the script from my text editor, press TAB in MoI, paste the script and hit ENTER without problems. I just tried it and copied and pasted directly from the browser window and it also worked fine. Maybe there's a clipboard setting in Windows to copy rich formatted text or something like this.

Unfortunatetly I don't know how to put scripts into a code box but here they are again with all line breaks removed. I chose the formated versions because it's easier to read.

script: /*draw box*/ var factory = moi.command.createFactory( 'box' ); factory.setInput( 0, moi.vectorMath.createFrame() ); factory.setInput( 2, 20 ); factory.setInput( 3, 20 ); factory.setInput( 4, 20 ); factory.commit();

script: /*draw cylinder*/ var factory = moi.command.createFactory( 'cylinder' ); factory.setInput( 1, moi.vectorMath.createFrame() ); factory.setInput( 3, 10 ); factory.setInput( 5, 40 ); factory.commit();


The first one draws a 20x20x20 box at the worlds origin axis the second one just a circle.

Thanks Martin. I'll try again later, after work. (Windows 7)

Okay, I managed to get a cylinder:

script: /*draw cylinder*/ var factory = moi.command.createFactory( 'cylinder' ); factory.setInput( 1, moi.vectorMath.createFrame() ); factory.setInput( 2, moi.vectorMath.createPoint( 0, 10, 0 ) ); factory.setInput( 4, moi.vectorMath.createPoint( 0, 0, 40 ) ); factory.commit();

Other than the box script creating x,y,z points is required to get it to work. Radius and height values obviously don't work.
I'm looking forward to your feedback bemfarmer.

Update:
Setting only the height value as x,y,z point also works:

script: /*draw cylinder*/ var factory = moi.command.createFactory( 'cylinder' ); factory.setInput( 1, moi.vectorMath.createFrame() ); factory.setInput( 3, 10 ); factory.setInput( 4, moi.vectorMath.createPoint( 0, 0, 40 ) ); factory.commit();

Hi Martin, it sounds like you've got it all figured out now?

Basically these factories are set up to work with the draw commands, so their input behavior will generally work the same as how the drawing command works.

For a cylinder there are 6 inputs:

0 = boolean value true = distance input is radius, false = distance input is diameter
1 = frame for cylinder bottom base point and axis directions
2 = point that defines the radius, this can be left out if a numeric radius is supplied instead
3 = numeric radius (or diameter) value.
4 = top point of the cylinder, this is required and also the orientation of the cylinder will be modified to point towards this point
5 = optional numeric height input, if this is supplied the cylinder will point towards the top point but will be this specific height instead of touching the top point


These map to the different possible options and steps in the drawing command.

A few little details makes a big difference.

I suppose if a person had the time, they could go through the forum, wiki, documentation, and create a tutorial or book about scripting.
Probably still a lot more to learn though.

Hi Brian,

> Probably still a lot more to learn though.

There's also a lot more to be done in MoI itself to make things more friendly for scripting - right now all the methods for creating geometry are all set up just specifically for how the regular drawing commands use them. I do want to add various other methods that would be easier for people doing automated scripts where they already know all the parameters instead of gathering them interactively like the drawing commands do.

But right now though more sort of regular feature work is still taking precedence over scripting related work. At some point in the future I do expect to focus some effort on scripting improvements though.

>4 = top point of the cylinder, this is required and also the orientation of the cylinder will be modified to point towards this point

Hi Michael, thank you. Yes now everything makes sense.

Thanks Michael.

Well, for what it is worth, none of these scripts work (for me) in MoI, in Windows 7 64 bit.
Neither in Tab entry, nor in Shortcut key.
Keep getting data type mismatch. Spent a couple of hours experimenting, no success.
Maybe something very simple, Mac vs WindowsPC ?


Also, copy/paste, Ctrl+C and Ctrl+V, only copy up to the first invisible CR/LF, when entering in MoI shortcut keys, but
the entire text is pasted in Notepad, or Notepad++.










Maybe I can blame it on .Net 4.5 (Joke)

Hi Brian, things may get confused when you're pasting in a long multi-line script into a keyboard shortcut, the keyboard shortcut is going to expect to have just one line of text.

It can be better to put the script into its own file (with .js file extension) in some folder like c:\scripts and then in the keyboard shortcut put the full path to the script file in there instead of pasting in inline script text.

If you're still having problems with doing it that way please post the script files here and I can test them.

- Michael

Thanks Michael,
I'll try some more, tomorrow. :-)

I just tried what Michael suggested, used notepad++ , created a line.js file in c:\scripts,
In MoI tab-> full path to script , worked ok for me... Win 7 64 bit, MoI 2.0. Don't have ver3 here at work


Cheers, steve

correction, create line works, but circle and box don't, type mismatch error... this could be a moi version 2.0 error?

Hi Brian, its time to get a Mac (just kidding).
I'm sorry to hear it's not working for you. Please try this one:

script: var factory = moi.command.createFactory( 'box' ); factory.setInput( 0, moi.vectorMath.createFrame() ); factory.setInput( 2, 20.0 ); factory.setInput( 3, 20.0 ); factory.setInput( 4, 20.0 ); factory.commit(); moi.view.resetAll;

The inputs require floating point numbers and that's the only "Type mismatch" I see. Maybe Windows is more picky than Mac.
Another thing to try is to put standard quotes around box like so: "box"


Also if you put the script into a .js file you should leave out the word script: at the beginning (I think).

I used the scripts successfully in version 2.5 and the newest 3 Beta.

>correction, create line works, but circle and box don't, type mismatch error...

The line script above is the only one with standard quotes. Maybe this is it.

It appears to be the call to moi.vectorMath.createFrame() - that function takes 3 optional arguments for an origin point and x and y axis directions, but those optional parameters are not behaving the same way between Windows and Mac at the moment, it's not working on Windows to omit those arguments right now.

If you switch that to call moi.vectorMath.createTopFrame() instead then it should probably work everywhere, like this:

script: var factory = moi.command.createFactory( 'box' ); factory.setInput( 0, moi.vectorMath.createTopFrame() ); factory.setInput( 2, 20.0 ); factory.setInput( 3, 20.0 ); factory.setInput( 4, 20.0 ); factory.commit(); moi.view.resetAll;

- Michael

Thanks for figuring this out Michael! And again I learned something new.
Instead of

Draw circle on xz (Front) plane

script:
var frame = moi.vectorMath.createFrame(
		moi.vectorMath.createPoint( 0, 0, 0 ),
		moi.vectorMath.createPoint( 1, 0, 0 ),
		moi.vectorMath.createPoint( 0, 0, 1 ) );
var factory = moi.command.createFactory( 'circle' );
factory.setInput( 1, frame );
factory.setInput( 3, 10 );
factory.commit();

I'll now use the much simpler

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

Edit: The former script is still required if the center of the circle has to be elsewhere.
The line moi.vectorMath.createPoint( 0, 0, 0 ) determines the center.

Hi Martin, you can also createFrontFrame() and then set just the origin of the frame by setting the .origin property on the frame.

So something like:

var frame = moi.vectorMath.createFrontFrame();
frame.origin = moi.vectorMath.createPoint( 5, 10, 2 );


Also for the next v3 beta I've tweaked moi.vectorMath.createFrame() so that the optional arguments there will work ok on Windows too when they are left out, there seems to be a little difference in behavior with how optional arguments are handled between the regular Windows OLE automation mechanism and the one in Wine, but it only takes a minor modification for me to make it work ok on both.

- Michael

That looks right. I replaced the line "factory.setInput( 1, moi.vectorMath.createFrame() );"
with the code used in Mirror script. The following script works in either of a shortcut key to c:\Script\DrawCircle.js
or with the whole script in a shortcut key line pasted from Notepad++ DrawCircle.js.

I forgot, (again), how to do \code or whatever it was.

The following is for Right view, and it works in Windows7:

script:/*DrawCircle*/var factory = moi.command.createFactory( 'circle' );var FrameOrigin = moi.vectorMath.createPoint( 0, 0, 0 );var FrameXAxis = moi.vectorMath.createPoint(0, 1, 0 );var FrameYAxis = moi.vectorMath.createPoint( 0, 0, 1 );var Frame = moi.vectorMath.createFrame( FrameOrigin, FrameXAxis, FrameYAxis );factory.setInput( 1, Frame );factory.setInput( 3, 10 );factory.commit();

It has been a good learning experience. :-)
That Dave Morrill documentation could use some upgrade, with lots of examples...

Okay, it is "less than sign" code "greater than sign,
and to end 'less than sign" /code "greater than sign.

>frame.origin = moi.vectorMath.createPoint( 5, 10, 2 );

Excellent, thank you again Michael.

This Dave Morill documentation helps a lot! What a huge effort! But I agree what's missing are the simple "Hello World"-type examples. On the other hand I fully understand that scripting or it's documentation can't have priority in the MoI development at this time.

Nevertheless one more question if it's okay:
I found moi.ui.propertiesPanel.editName() which brings up a dialog to edit the name of the selected object but I can't find out how to give an object a name directly without dialog.

Code looks good. Can you use it with copy and paste formated like this Brian? :-)

Boolean Union of selected objects:

script: /*boolean union*/
var factory = moi.command.createFactory( 'booleanunion' );
factory.setInput( 0, moi.geometryDatabase.getSelectedObjects() );
factory.commit();
