Create Points along Element location curve @ specified Distance

[zrodgersTSSSU]

Hey Everyone, Im trying to put points along a location curve @ a set distance. I need the points to place a family. Can anyone help me with this??

                                        LocationCurve eleCurve = elem.Location as LocationCurve;
                                        

                                        //start and end points of pipe
                                        XYZ startPoint = eleCurve.Curve.GetEndPoint(0);
                                        XYZ endPoint = eleCurve.Curve.GetEndPoint(1);

                                        //get length of curve
                                        double pipeLength = startPoint.DistanceTo(endPoint);

                                        //new points list
                                        List<XYZ> pts = new List<XYZ>(1);

                                        //place points along curve (need help here)





                                        //sets family @ points
                                        FamilyInstance placedInst = doc.Create.NewFamilyInstance(startPoint, hangerFamily, Autodesk.Revit.DB.Structure.StructuralType.NonStructural);

Hello @zrodgersTSSSU,

The Curve.Evaluate() method will return a point at a specific location, location being a number between 0 and 1, on your curve.  For instance this will return an XYZ point 1/3rd the length of a bound curve from the start point.  

var oneThird = 1.0 / 3.0;
var pointOnCurve = eleCurve.Curve.Evaluate(oneThird , true);

thank you that worked!!

You are welcome.  Glad this one didn't throw you too much of a curve!

OK, I'll go sit in my corner now.
