OpenDocument twice

[jacknotreally]

maybe this is very stupid.
I am not able to open the same file twice inside FreeCAD with App.OpenDocument().
The second one should behave like a separate file.
Creating a new document and import the "second" file from disk would also be ok.

Or do i have to make a workaround and have to copy of the file on disk.

An easy way is to create an empty document and then go to File > Merge projects.

More detailed:

Im using FreeCAD without GUI and having a drawing that consists on several FreeCAD documents.
Each FreeCAD document is imagined as an "assembly" inside my drawing.
So its is very easy to handle these "assemblies", because they are still separate FreeCAD documents.
The user is able to open a FreeCad file as a document (assembly) and to change some parts.
If he opens the document a second time (as an additional "assembly") this should be the latest file version,
not the one being loaded before and may be changed.

OK, you can achieve this with a little trick. But be careful it's up to you to not override the file with another document.

Code: Select all

App.openDocument("C:/project.FCStd")
d=App.newDocument()
d.FileName="C:/project.FCStd"
d.restore()

Hi Werner,

nice trick!

Thanks

What you probably want to do is planed for the Assembly workbench. Its a document link object.
You have one document with links to other (open or not) documents. There you can link the same document twice with different
positions. Thats the classical way Catia does it.

It makes no sense in the long run to have two documents in memory with the same data....

In FreeCAD 0.14 Doucment.FileName is read only.
Is there another way to open a Document twice?

Thanks

No, not at the moment. Maybe in the restore() method we can allow an optional string parameter to make this working again.
However, it must not collide with the points listed here: viewtopic.php?f=8&t=4000&p=31509&sid=28 ... 7c8#p31509

Please notice that we have a new forum section dedicated to help with python scripting. Accordingly, I moved this topic here from the "Help about using FreeCAD" forum, which is about using FreeCAD's GUI.

There is now a method load() in the Python Document class where you can open a project in another document instance.
