No warning while Unfolding sheet metal with API

[darryl.menezes]

Hi,

   I am trying to create Flat pattern of a geometry using Inventor API. But when the flat pattern is created, I can see that the plates are interfering. But yet, I get no warning which says that there is an interference after unfolding. However, when I use the 'Create Flat Pattern' command on Inventor, it shows the warning. Below is the c# code. Is there anything missing? Thanks.

                oDoc.SubType = "{9C464203-9BAE-11D3-8BAD-0060B0CE6BB4}";

                SheetMetalComponentDefinition oSheetMetalDef = default(SheetMetalComponentDefinition);
                oSheetMetalDef = (SheetMetalComponentDefinition)oDoc.ComponentDefinition;                          
                SheetMetalFeatures oSheetMetalFeatures = (SheetMetalFeatures)oSheetMetalDef.Features;
                oSheetMetalDef.UseSheetMetalStyleThickness = false;

                oSheetMetalDef.Thickness.Value = 3;

                oSheetMetalDef.UseSheetMetalStyleMaterial = true;

                oSheetMetalDef.Unfold();

Any joy with this? I'm experiencing the same issue

Hi,

    You can use the error manager object to detect any warnings. For example, for the above code, we can detect any warnings during unfold as follows:

           

            SheetMetalComponentDefinition oSheetMetalDefinition = default(SheetMetalComponentDefinition);
            oSheetMetalDefinition = (SheetMetalComponentDefinition)oDoc.ComponentDefinition;                          
            SheetMetalFeatures oSheetMetalFeatures = (SheetMetalFeatures)oSheetMetalDefinition.Features;
            oSheetMetalDefinition.UseSheetMetalStyleThickness = false;

            oSheetMetalDefinition.Thickness.Value = 3;

           
            
            ErrorManager oErrorManager = ThisApplication.ErrorManager;
            MessageSection oMessageSection = oErrorManager.StartMessageSection();

            Transaction oTransaction = ThisApplication.TransactionManager.StartTransaction((_Document)oPartDoc, "Unfold");

         
            oSheetMetalDefinition.Unfold();
           
            
            if ((oMessageSection.HasErrors) || (oMessageSection.HasWarnings))
            {
                    oMessageSection.AdoptMessages(oErrorManager.LastMessage, true);

                    oTransaction.End();
                    oTransaction.Abort();                   
            }
