Wrong Layer while importing PDF

Hey there. While importing a PDF file in Rhino with lots of layers rhino imports most of the objects correctly. But some of the objects are set on layer “0”. Had the problem now with many different pdf files. What can I do about it? I need the layers as the are…

Hi - please post a file that is not behaving as it should so that we can take a closer look.

dear @hauptsachetiny
my recommendation / best practice for file-import, that efforts correct layer-setting:
import the file to an empty rhino-document - make sure / correct the layers in this “helper” document - copy paste from rhino helper document to rhino big work document …
kind regards - tom

Thanks @Tom_ . That doesnt work neither. Some items will be placed on layer “0”.
Please see the file attached @wim

Btw got similar problems when opening a DWG / DXF File. Some (but other items) will be placed on a different layer…

Hello - layer 0 is an autocad thing for handling blocks. Do the pdfs originate in Autocad?


Yes they do

Hi Aurèle -

As Pascal wrote, AutoCAD will place things on a layer called “0”. When you open your PDF file in Adobe Acrobat Reader, you will see that the “0” layer contains the same objects as when you import it in Rhino. So that part is correct.

On the other hand, I see that some objects are placed on the current layer in Rhino when importing the PDF and there appears to be a layer without a name. That is different from the result in Acrobat Reader and we’ll take a closer look at that.
