This is the error I am seeing.
The script tries to get the length ālen()ā of the list of views āIn[1]ā to iterate for all views.
This means that your input is not a list. Looks like you have connected the wrong node.
IN[0] = List of dwg file paths
IN[1] = List of Drafting views
If both lists are the same length it will import all dwgs on the views.
If for some reason you want to put all the dwgs on one view, use ālist of repeated itemā to make a list the same length with the single view.
Should be connected something like this;
So I got it working. I canāt take credit though. An associate Jason Boehning from our training content provider Cad learning pointed out a case error between āLinkedElemā and ālinkedElemā. Once that was corrected it works.
Hey Gui,
Sorry to resurrect an old post here, but Iāve been working for hours and feel like Iām so so close here. If I could get a little assistance I think Iād be there. Iām trying to take the code to import in CAD files and have the output be the linked file (either the elementID or the element itself). As you explained in your post above, the clr.Reference as I understand it acts as a function reference, so you canāt pull values out of it by itself.
Iām following the posts you linked above and feel like Iām close, but I canāt quite get it. Iām getting the boolean to fall out, but I canāt get it āTrueā, much less get a value from it. Iām very new to python so Iām trying to figure all this out. Any assistance or advice would be greatly appreciated.
@Konrad_K_Sobon thanks for your code,
Itās possible ton add in your python script, a out parameter with instance of dwg ?
i would like attribute a workset in a dwg file after link.
thanks for all
Best,
Hi RĆ©my,
One possible way is to change the output to provide Filepath.
And with a string contain and a boolean mask you will obtain the ImportInstance.
Drafting View.dyn (13.5 KB)

Ok thanks @Alban_de_Chasteigner Alban, I thought there would be a more direct solution.
What is the package for a node Passtrough ?
Passthrough is from Clockwork.
ImportInstance is not a commun Revit Categorie so itās no easy to manipulate in python but more skilled users should have a better solution.

Ok thanks, clockwork is a great package !
Hi
I have tried running your script but canāt work out why the visibility isnāt showing ? Do I perhaps need to redefine the options.x in the python script? Iām trying to run this in Revit 2018 so not sure if the API has much differences in these settings?
It appears in my manage links - in my VG settings though it doesnāt, I checked under the Imports in Families and it isnāt displaying any layers relating to the CAD link either ? itās only showing the already imported not the import from the script
Once I look at my view I also canāt see the CAD link appearing in my view? but Revit is telling me it has been linked - I have already done everything I can think of in that regard of making sure the setting view range etc are correct. I tried manually linking to make sure it wasnāt the dwg file and it came in fine.
If you know why this may be happening please donāt hesitate to let me know! Iāve been investigating for hours and I havenāt been able to identify the issue - need another perception
Hi Jade,
It is not my script but that of Konrad Sobon.
I donāt see any change in the API :
http://www.revitapidocs.com/2018.1/19f4cadb-53eb-5e85-5289-022d24c076b0.htm
It may have something to do with the units or the placement
You could add the lines :
options.Unit = ImportUnit.Default
options.Placement= ImportPlacement.Centered
And change the values āDefaultā with your unit and āCenteredā with Shared or Origin or Site.

Thanks for responding Alban.
I found the DWG it had come in on the sheet for some reason instead of the Level view. Will work a way around that.
Actually would you happen to know how I specify the level of placement in the script? Iām not sure of the argument arrangement.
Hopefully, folks are still watching this feed itās been awhile since any one posted to it. I have a a script that used the python code from here to link in a DWG to a drafting view and everything works, except for the issue that the line styles are coming in as solid lines in Revit but are dashed or hidden within AutoCAD. It looks like the linking process is not bringing in the actual line pattern since all the line patterns for the linked line styles are blanks.
Here are some screenshots of the results vs AutoCAD.
Any thoughts or suggestions would be greatly appreciated.
Thank you in advanced!

Can you share the link of solution here please, I canāt find it 
Thank you!!
Please start a new topic. This thread is 2 years old.
If you want to import DWGs, there are some existing custom nodes in packages for this purpose.
