Hi Frederick,

re:
> But what is generating the prompt?

It's the call to GetObjects().

The object picker will only target preselected objects if the selection happened before the command started.

Since you want to automatically select stuff instead of having the user pick them you probably don't want to use the object picker there at all.

Instead of calling GetObjects() you could call moi.geometryDatabase.getSelectedObjects(); and to wait at the prompt you could call WaitForDialogDone() instead of GetObjects().


> The .HTM file - that provides a user interface if needed?

Yes the .htm file has the UI for the command which will be loaded into the command options area in the upper right of the main window.


> Is it required?

No, if the command doesn't want to show any UI there the .htm file can be omitted.


> What invokes that file?

It's part of the "command" infrastructure. When you run a command if there is an .htm file present it will get loaded into the command options area before the .js code is run.


> Can you use that file to collect input and feed it into the script?

Yes you can put controls in the .htm and the script can access them.

Hi Michael,

Thanks very much for the feedback.

Since you can collect user input from the .HTM file, and I gather there is no real documentation, do you know of a good example, that is simple enough to learn the basics from?

I think I'm getting the hang of this stuff.

Hi Frederick, I've attached an example here.

Hi Michael,

Thank you.

Going back a post or two to where you mentioned this:

-The object picker will only target preselected objects if the selection happened before the command started.

-Since you want to automatically select stuff instead of having the user pick them you probably don't want to use the object picker there at all.

-Instead of calling GetObjects() you could call moi.geometryDatabase.getSelectedObjects(); and to wait at the prompt you could call WaitForDialogDone() instead of GetObjects().

I could not get it to work.

See attached.

Thanks.

Hi Frederick, almost - so what I meant was get rid of all the objectpicker stuff and you can get the selected objects by the return value of moi.geometryDatabase.getSelectedObjects(), like:

var objs = moi.geometryDatabase.getSelectedObjects();

And now that it's selecting objects by name there won't be any unnamed objects selected so I think you can skip the deselectUnnamedParts part as well.

So maybe just this (untested):

function ExportByPrefix() {
mgd.deselectAll();
mgd.selectNamed(pfix);

WaitForDialogDone();

DoExportParts( mgd.getSelectedObjects() );
}


re:
// what are these 4 lines below supposed to do

Those were updating the prompt (the top line in the command options area) by hiding one line of text and showing the next one.

Hi Michael,

That seems simple enough.

I will give it a try shortly.

Thanks.

Frederick
