Hi all, I have a question: How can I join line and arcs to a polycurve? I’m trying to create rebar by calculating the start and endpoint of the lines. The lines are connected via an arc and then joined as a polycurve. So far I can only join 2 lines and a curve to a polycurve (see line lightup bl…

FRIKKING H*L!!! I found my problem! My approach was correct. It was the startingpoint of the top line that wasn’t the same as the endpoint of the arc. My calculation was off. @Ewan_Opie : in your great example you make use of horizontal en vertical lines. But in my case the top line is sloped and …

Even if the start and end points of the curves and arcs are sequential, the node is still only expecting a single curve as the first input. With some list management this should be an easy fix. You can the Polycurve.ByJoinedCurves node instead if all the curves do join, as this ignores ‘start / en…

Thanks for your replay Ewan! I was just looking through older dynamo files of mine and found out I already made this work. So I copyed what I did before… but it didn’t work! Sadly. So I tweak it here and there and got rid of the error but stil got 10 polylines instead of 2 polylines that are made…

If possible, upload your script and I can take a look.

Just looked at a design script alternative (DS +1 :+1:), based on what i can see of your script / background. This may help… but if not, should be a good reference for others. [image] //design script only :slight_smile: //control points a=Autodesk.Point.ByCoordinates(0,0); b=Autodesk.Point.B…

Archilab’s group curves node may be worth a look here… The polycurve by joined curves node fails as soon as it finds a curve which doesn’t connect with another…

I have problem with joining curves also. I exploded 3 sweep elements and found their section profile which is generated by multiple lines. Now I want take all the lines and create 3 polylines to corespond with the shape. I used 2 nodes, one made by @Vikram_Subbaiah (GroupCurves) which generates 28 p…

Group curves works only if there aren’t any branching curves. In other words - They might not be in the proper sequence, but there should be no ambiguity as to which curves form a closed loop. While it might not always work, you could refer to code from here to group branching curves.
