I have an irregular curtain wall in Revit. It has angled edges. I am pulling the non-rectangular edge panels into Dynamo, tracing them and using the corner points to place adaptive components. When I create the polycurves from the panels, I get a list that has some with 4 points, and some with 6 poi…

Spring nodes has a node called “CurveLoop.Simplify” that might help. Tho you’ll need to make a small revision to make it work with Dynamo 1.0. I haven’t had a chance to update the package to 1.0 yet. [image] The problem is that the node uses a script and unlike the OOTB nodes, script does not get…

[image] sp1=pn1.Curves().StartPoint; ep1=pn1.Curves().EndPoint; dr1=List.DropItems(Vector.ByTwoPoints(ep1,sp1),-1); dr2=List.DropItems(Vector.ByTwoPoints(sp1,ep1),1); msk=dr1.IsParallel(dr2); pn2=List.FilterByBoolMask(List.RestOfItems(sp1),msk)["out"]; pn3=Flatten({sp1[0],pn2});

Another way … This is what I first thought of. Not the most efficient, but will do the job. [image]

Thanks for the replies. I will try these suggestions later today and report back. Much appreciated.

I downloaded Spring Nodes and made the change indicated. However, I am ending up with 5 points on two of my shapes. The other two came in with 4 points. So I am thinking maybe there is a precision issue? These shapes come from curtain panels in Revit. So maybe they are off just a little? [image]

Hi Vikram: I tried this graph and at first was having trouble, but when I added a List.Map it worked. Now the trouble is, I am getting five points instead of 4. Maybe the same issue I noted above with the Spring Nodes option? A visual scan of the points seems to be four-sided, but maybe along the d…

@Paul_Aubin Instead of a list of panels, to see if it works, try it on one panel.

Sadly that does not seem to help. I still get five points [image] Thanks

Hi Paul, Is it possible to drop here 6 points panel family and dyn file so that we can have closer look at it. Thanks :slight_smile:

Certainly. Thank you for taking a look! Sample Facade_C.rvt (1.7 MB) Edge Panels_C.dyn (21.7 KB)

Hi Vikram:
This also works great! Thanks.
