Polycurve from DWG file

[robertobatista]

I’ve imported a DWG file using BIMmorp’s CAD.CurvesfromCADLayers. The DWG files consists of polycurves yet when I import the DWG file, the curves are converted into flattened dynamo lines. If all DWG polycurves consisted of 4 lines, then I would have been able to simply create sublists of 4 and join these curves into polycurves. However many polycurves consists of more than just 4 lines. Is there a way to create joined polycurves based on DWG polycurve?

es.

P.S. I also tried tracing the DWG curves using model lines in Revit and then importing them, but Models lines also come in as a flattened list and not grouped.

Have you tried Grouping the Curves?

Grouping Curves with Design Script

Design script definition that groups a list of shuffled curves into loops… [GroupCurves] On the package manager search for tstngwtrs-GroupCurves However the node doesn’t need to be downloaded, paste the below code in a code block and call grpCrvs(crv) def grpCrvs(crv:var[]..[]) { dis1 = (crv.StartPoint)<1>.DistanceTo(crv<2>)==0 ||(crv.EndPoint)<1>.DistanceTo(crv<2>)==0; ind1 = List.AllIndicesOf(dis1<1>,true); bln1 = true; ind2 = [Imperative] { …

I tried using that method, but i didn’t work. The list returns null.

@robertobatista I did a similar on the Graphical package, GroupCurves node.
It does work quite fast. A similar approach is used at the beginning of the video below to group lines from a dxf file as polygons.

GroupCurves node worked. Thanks!!

great

@robertobatista I suppose you’re using ver 2.
Please try the updated code for grouping curves with Design Script
