Hello everyone,

this is my first time posting here a question in the forum=) I recently started working on RhinoCommon and RhinoCompute. I have been facing issues when converting our RhinoCommon PlugIn.  
I hope this is the right place to discuss the problem I ran into:

Till now we are using Open() and we don’t have any issue opening and generating reports from it.

Apparently, I am running into an issue when using the RhinoDoc Methods:

- [OpenHeadless()](https://developer.rhino3d.com/wip/api/RhinoCommon/html/M_Rhino_RhinoDoc_OpenHeadless.htm)

When I open **.3dm** file using OpenHeadless() method, it’s unable to load layout properties properly. I can view all the layouts in **doc.Views** but the **layouts are not loaded properly**. Views like Top, Bottom, Right, Left… are loading fine.

**doc = RhinoDoc.OpenHeadless(@“C:\Sample.3dm”);**  
Works fine when i use  
**doc = RhinoDoc.Open(@“C:\Sample.3dm”);**

Regards.

Hey @Rama_Shashank ,

Have you tried File3dm?

> **[File3dm.Read Method (String, File3dm.TableTypeFilter, File3dm.ObjectTypeFilter)](https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_FileIO_File3dm_Read_1.htm)**

> Reads a 3dm file from a specified location.

I tested this by creating a file with a layout and one detail. I use RhinoDoc.OpenHeadless() and in doc.Views I see 4 RhinoView and 1 RhinoPageView.

What I do see is that the loaded RhinoPageView has bounds of {X=0,Y=0,Width=0,Height=0} where as if I open the file directly, the bounds are {X=0,Y=0,Width=283,Height=200}

Yes, that’s the issue.  
I can’t read RhinoPageView which stores layout details. All the properties are set to default.  
But when I open Rhino I can see all the details.

Till i get the proper fix, I will try to use **File3dm.Read()** method to read the file.

Yes,  
When I use File3dm.Read() method can see the info I needed.  
Thank you.

Need to check if there is anything that’s missing.
