AC25 IFC export with warning

George_H

I have a serious problem. When I want to save the model into IFC format, the program gives me a warning that is the following message: "The output file cannot be written!"

With other model files it works, but with this only one it doesn't. Is Anybody familiar with this issue?

You can also try "Find & Select" elements (walls, columns, etc.) with zero or inverted height.

Thank You All for the quick help. I think I have found the source of the problem. There are several unclear wall joint which can affect the export procedure. we are to modify these elements.

Sounds like a permission issue - do you have write permission enabled for the drive/folder you are saving into?

Please put some information about your OS, hardware and AC version into your signature, this way everybody will have better understanding of what might be wrong.

OS and HW info given. I have permission for my own computer secondary hard disk folder.

And if it is not a permission problem, then check the file name and path you are trying to save for strange characters that may not be acceptable.

Path is short, and no special character written into file name or folder name, or even path name.

I would like to share some new piece of information: I put down a new 3D column separatly, and IFC export for this column worked, to same folder and file name. There is something in the model - some kind of element, somewhere - which make errors. So next step to find this model element. But how? Our model is huge.

Divide and conquer maybe?

When you save the IFC, does it save just what is on the screen?

If so turn half the layers off and save IFC.

If there is no error, then you know the problem is in the other layers, so turn them on.

 

Which ever set of layers has the problem, turn half of those layers off.

Save again.

 

Repeat until you can narrow it down to a specific layer.

 

If there are many elements in that layer and you can't figure out what might be the cause, you can do the same by temporarily deleting half of them.

May be best working on a copy of the file so it doesn't matter if you destroy it.
