Autodesk Forge-Automation- IFC Export

Question

I am trying to do the IFC Export through Autodesk Forge. I am using Automation API. The code was working fine earlier when I used to just have the conversion to Revit from my model. I extended the same code with flag based approach ( by passing the parameter in the command line parameters to Forge App).

The code is working fine on Local but when I am trying this on Cloud, it is somehow returning the same IFC file every time irrespective of the input model passed . I tried to have the debuggers to see if the model I am passing is getting transported to Forge corrected or not . They are ok. Till the last step , the inputs values are ok, but not sure where it is going wrong after the Export or during the export. I am using

Document.Export

method from Autodesk API to convert to IFC.

The status of the Work Item is Success as can be seen by the report that is downloaded from the reportUrl.

It is hard to tell without a sample, would you mind copying the content of the result.txt file, and the input/output parameters you are using? That will help to understand what's wrong. — cyrille

Hi Cyrille , Thanks for reverting. I have added the contents of the result.txt in the post . This will also give you the idea about input and output parameters. — rnilay81
– rnilay81, Commented Jul 6, 2021 at 1:11
Hi Cyrille , one thing I wanted to clarify --- Can this problem be related to some issue in calling the Export function ? I am calling this as below Boolean retValue = doc.Export(@".\", "results1.ifc", opt); =================================== so in this case , I was not sure how to use the directory when it is on Cloud ? Just asking if this has got something to do with the problem. — rnilay81
– rnilay81, Commented Jul 6, 2021 at 4:59
The code to export IFC file looks good, usually, we use Directory.GetCurrentDirectory() as currently folder path in Revit cloud engine, but your code should also work good. Since you mentioned you always get the same IFC output file, I suspect the input file is not respected, can you make sure the input file is correct? — Zhong Wu
– Zhong Wu, Commented Jul 6, 2021 at 10:53
@ZhongWu Thanks. I have checked. I added console writes in the program to print properties from the input to make sure it is the correct one ( I have not pasted the contents of those in the question above for brevity ) . I couldn't however find the way to check if the resultant results1.ifc is the correct one. Is there a way we can open the IFC and read some properties from it programmatically like the way we open it in normal Text Editor. Or secondly is there a way to see if the different files are getting created at the Forge end at least and some problem at the download time at our end ? — rnilay81

The problem was with respect to the reference of the Document object being passed while calling the Export method. Once I fixed that, the IFC models started generating successfully depending on the input.
