Exporting ViewSheet element through ExportContext2D

Hello,

 

I am trying the use the ExportContext2D to export a ViewSheet type element.

 

I am receiving the following error:

pmeigneux_0-1605200654000.png

 

Here is a sample of code that I use:

            FilteredElementCollector colS = new FilteredElementCollector(Doc).OfClass(typeof(ViewSheet));

            foreach (ViewSheet sheet in colS)

            {

                            try

                            {

                                ExporterAdnMeshDS_UPS.ExportContext2D context = new ExporterAdnMeshDS_UPS.ExportContext2D(Doc);

                                CustomExporter exporter = new CustomExporter(Doc, context);

                                exporter.Export(vs);

                                exporter.Dispose();

                            }

                            catch (ArgumentNullException e)

                            {

                            }

                            catch (ArgumentException e)

                            {

                            }

                            catch (InvalidOperationException e)

                            {

                            }

}

 

Do you know an alternate way to realize the export of a ViewSheet? I was maybe thinking to convert it into another view type. Any best recommendation on it?

 

Thanks

You are looping over all the ViewSheet elements that you encounter, without checking anything further.

 

I believe you should always check for and eliminate template views, for instance.

 

I would suggest that you export the view sheets one by one and determine exactly which one causes a problem.

 

Maybe it is one that you should be skipping anyway.

is it possible to export by CustomExporter2D viewsheets other than templates?

the viewsheets that I want to export, exort correctly with Doc.Export in dwg.

I tried to implement a test and encountered no problem whatsoever.

   

Here is the result of exporting the Level 1 view with a trivial 2D custom exporter implementation:

   

Sample view:

Sure.

   

I tried using the custom exporter that I implemented above (attached) on your sample model and see that you are trying to export a sheet view.

 

I can reproduce the behaviour you describe:

  

custom_export_2d_view_not_exportable.png

 

Please read the documentation on the IExportContext2D interface; it clearly states: An interface that is used in custom export to export 2D views of a Revit model. I am sorry to have to point out that a sheet is not a 2D view of the model. That is presumably the reason why this exception is triggered: the view is not exportable, indeed.
