Combine multible Modellines

[Anonymous]

Hi,

i am new to Revit API programming and was wondering if there is a possibility to combine multible modellines.
Via uiApp.ActiveUIDocument.Selection i have the option to pick modellines and get access to the geometry of each element (with LocationCurve) as shown below:

var pickedRefs = selLine.PickObjects(ObjectType.Element, new ModellineFilter(), "Pick Modellines.");

foreach (var refer in pickedRefs)
{
   var elementCurve = doc.GetElement(refer);
   var locationCurve = elementCurve.Location as LocationCurve;
   Curve curve = locationCurve.Curve;
   // ?  
}

Now i want to combine those curves to one single curve element, so that i can access the complete geometry and be able to use curve methods like curve.length. It should also be possible to set referencepoints according to the entire curve via PointLocationOnCurve.

I hope there is an opportunity to realize this kind of conversion via the Revit-API.

Can you be more specific and tell what is the state of model lines?

Are they straight, curve or there is space between them?

There is no space between the model lines and there are both straight lines and curved lines.

For instance like those modellines

Hi,

A Bit late,

Total length can be done by sum all of the curve.length's??

I've never used PointLocationOnCurve myself , but  can't you create a wrapper or separate class which takes multiple lines and returns the correct results (loop each line and evaluate what the app needs....)

Thanks for your answer.

Yes sure i can add all curve.lengths together, to get the total length.
 
But this is not my main problem. I need one geometry reference of the whole curve object to place a reference point on a certain station and do other things with it.
If i would use a wrapper i'd have to calculate all geometry data & references of each curve segment by myself, which is in some cases impossible.
