I am quite new to dynamo so please forgive my node structure which might be a little bit rough. I know there are multiple topics both here on this forum and elsewhere regarding this issue however I encountered an error message that I couldn’t yet resolve.
I am trying to extract contour lines from a toposurface via dynamo beacuse the basic export to .dwg renders very unnatural and jiggly lines. I have found a soution here (Retrieve topo contour lines and smooth curves - #3 by BIMadmin) and tried applying it, however it doesn’t work for some reason. The Element.Geometry node throws this error: “Warning: One or more geometries have failed to convert due to this error: PolyCurve objects may be branching.”, and the PolyCurve.Fillet node: “Warning: PolyCurve.Fillet operation failed. The PolyCurve object could not be rounded. : DEGENERATE_OFFSET – The offset wire is degenerate.”.
Could You please help? Either by modifying or completely overwriting my nodes? Thank You very much in advance!
