Trying to run the SavePointFile script on V5. Has something changed in the API that would prevent it from running? It just quietly dies after done or cancel. It appears that ObjectPicker is not collecting anything.

Hi probotix, the very original one made for MoI v2 I think used ActiveX controls for file I/O which won't work on v4 or v5.

But there's an updated one here using the cross platform file streams, it should work on v5:

Yes, that's the one I am using.

Also, I can get _SavePointNetwork to work, (it uses ObjectPicker.allowStandaloneCurves), but the point data is not correct. Yet, _PointCoord works fine and gives displays the expected data, but its quite different because it uses createPointPicker instead of createObjectPicker.

Okay, maybe I dont understand how SavePointFile works. If I create just raw points, it works fine. But what I want to do is find the points of a polyline or curve and export those points.

Not exactly the same ... i have not the original ...only in French...

Okay, I have the basic functionality of what I'm trying to accomplish:

function arcCAM()
{
var ObjectPicker = moi.ui.createObjectPicker();
ObjectPicker.allowCurves();
if ( !GetObjects( ObjectPicker, true ) )
return;

var curves = ObjectPicker.objects;

//alert(Object.keys(curves.item(0).getSubObjects()));

for ( var i = 0; i < curves.length; i++ )
{
var segments = curves.item(i).getSubObjects();
for ( var j = 0; j < segments.length; j++ )
{
var segment = segments.item(j);
var type = "Line";
var arcCenterX = 0;
var arcCenterY = 0;
var arcRadius = 0;
if ( curves.item(i).getSubObjects().item(j).isCircle || curves.item(i).getSubObjects().item(j).isArc )
{
type = "Arc"
arcCenterX = round(curves.item(i).getSubObjects().item(j).conicFrame.origin.X, 3);
arcCenterY = round(curves.item(i).getSubObjects().item(j).conicFrame.origin.Y, 3);
arcRadius = round(curves.item(i).getSubObjects().item(j).conicRadius, 3);
}

alert( "Curve " + i + "\n" +
type + " " + j + " start: " + segment.getStartPt().x + ", " + segment.getStartPt().y + "\n" +
type + " " + j + " end: " + segment.getEndPt().x + ", " + segment.getEndPt().y + "\n" +
"arcCenter X " + arcCenterX + "\n" + "arcCenter Y " + arcCenterY + "\n" + "arcRadius " + arcRadius + "\n");
}
}

}



Now how can I find out the properties and methods of getSubObjects().items? I cannot find it documented anywhere and it appears to be hidden in the binary code. Object.keys() doesnt work at the segment level.

Hi Probotix,

Re:

That's called a CurveSegment and all the methods and and properties are listed in the API:

Re:

There's a dump function in the Hints section near the top of the API to do that.

Yes SavePointFile will only export point objects, not "edit points".

To export those you can convert selected curve edit points to point objects by copy/paste (ctrl+c/ctrl+v).

In v5 it's also possible to access the edit points by script, that would go like this:

var numpoints = crv.numEditPoints;
for ( var i = 0; i < numpoints; i++ )
{
    var pt = crv.getEditPoint( i );
    // use pt.x, pt.y, pt.z
}

Can you be more specific about how to use the dump function?

Hi probotix,

re:
> Can you be more specific about how to use the dump function?

Get the file MoI_v5_API_Documentation.htm from here:
https://moi3d.com/forum/index.php?webtag=MOI&msg=10857.36

That has the code for a dump function, copy the dump function into your script and then you can call dump( obj ); which will list properties of that object.

Thanks Michael!

Is there a way to launch Moi from a console and print debug info from my scripts?

Hi probotix,

re:
> Is there a way to launch Moi from a console and print debug info from my scripts?

Sorry no there isn't a way to print debug info to a system console.

A script can show a dialog box message using moi.ui.alert( 'text' ); or it can also write to MoI's log using moi.log( 'text' ); .

You can show the log using:
moi.ui.createDialog( 'ShowLog.htm' );
