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.
