Linetype & color by Object

Civil3D
1

I want to achieve the exact opposite mentioned in this thread, namely getting first the Layer styles for Color and Linetype, then transfer these settings to the objects as Object styles. Reason for this is using CAD Links in Revit and maintaining Object styles after Layer Merge in Civil 3D. Revit has a known problem with CAD Links containing many DWG Layers and Linetypes.

This doesn’t seem to hard to do, there is a SetColor node with Object input but I didn’t find any SetLinetype node with Object input, only Layer.

Anyone know how to do this?

This isn’t great, but it works. I didn’t get the Python script to handle sublists in the time that I had - that’s why you have to flatten everything first. Maybe you can make it better.

Thanks @mzjensen, will have a look at your script. Hope we will get a standard Object.SetLinetype added someday. I managed the lists already in my script and was able to do the colors which is working nicely.

I’m noticing an error in the code above. It should be:

i.Linetype = linetype[count]

I’ve edited the post.
