Show messages:  1-7  8-27  28-42

ok, commands folder, I did made in in the ui folder, ok, sorry ... but I was a long abstinent ;) and I use first time scripts in moi

---

new version of the script.

The zip file appears to be empty. ?

Brian, thank you. Reuploaded. :)

Max,
That is Banner! Thanks for taking the time to do that, and also share it....

I see you made a "copy to clipboard" for the labels which is very slick.....

I suppose there would need to be one more tweak to the labeling? I didn't think about how they would stack up on various curves/situations and MoI's texts are not "blocks", so they can become kindof unmanageable.

I was trying to imagine how that would/could be handled. It may get too complex/unwieldy to give each text block an "object name" of it's value, as it's created? Or it would have to be a vertically constrained list. The only real option would be to have them orient off the positions normal, and have a "distance away from point" value for closer sets, to remain separated.

It may just remain a great option for points that aren't too close....... It can provide some quick communication in the viewport.....

Anyway, thanks again. Nice.

Somptuous!

Max, thats it, thats exactly what I need. Especially the skip straight lines option is a huge timesaver. Great work! Thanks for sharing.

Hi Max,

Thanks for the script. It will be a time saver for me.

Any chance of the new points made a new curve, above the reference curve and with an option (tick box) of deleting the reference curve?

Or placing the new points on the same curve and deleting the old ones.

Don't now if its possible, easy to do, or usefull for anybody else but me. Have a similar script on Illustrator.

The option 'skip straight lines' is fantastic.

try this who connect some selected Points ;)

"""""""""Any chance of the new points made a new curve, above the reference curve and with an option (tick box) of deleting the reference curve?""""""""

I've fooled a bit with this to help with reverse engineering some things. I can test various tolerance inputs with this.

So if the script is not made more robust with these types of requests, here's an option for what you want.

You can use the script to generate the points you want, then use "SavePointFile" on those points. You can then "ImportPointFile" and choose the option to create a throughpoints curve from the import.

Anyway...... Thanks again to Max for sharing his scripting work.

Hi BurrMan,

Make some attempts with your sugestions but couldn't get it to work. Will keep trying.

Anyway, thanks for your help.

Hey Carlos,
Not sure whats happening for you. It could be the point structure is not good for a "full through points" import?

Here's a video of a workflow:



Notice I have to break out anywhere where the points are the "straight lines". The through points tool wont know how to do that.

So anyway, maybe this helps. You can always revisit with questions of you need.

Hi BurrMan,

Its working now, before i was saving as .3dm file and not as a .txt (never heard about this scripts before you mention).

Thanks for help and taking the time to make the video. Fantastic.

This is an amazing community!

Cheers

Hi Michael,


I tested that with todays beta, two selected polylines and the code below. It works fine. Thanks a lot for adding this!

script:
var curves = moi.geometryDatabase.getSelectedObjects().getCurves();
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);
		moi.ui.alert( "Curve " + i + "\n" + 
		"Segment " + j + " start: " + segment.getStartPt().x + ", " + segment.getStartPt().y + "\n" +
		"Segment " + j + " end: " + segment.getEndPt().x + ", " + segment.getEndPt().y );
	}
}

You're welcome Martin, I'm glad that worked!

Also another new thing related to polyline handling in the new beta - for the Rebuild command there's a new "Endpoints" mode which builds a new smooth curve that goes through the endpoints of the current curve's segments rather than sampling points at percentages along the curve's length. This can be useful for building a smooth curve through imported polylines like you sometimes get with PDF or DXF imports. It's basically the same as doing a "Through points" curve snapping each point onto polyline segment endpoints, but doing it all in one go.
