CheckIfSheetMetal Activity

Purpose: This activity checks if the specified part or assembly contains Sheet Metal features. Sheet Metal parts have specific characteristics and require special handling for operations like flattening, bending, and exporting to DXF format.

Input Properties

DocumentId

The SolidWorks document ID. This should be the document ID returned by activities like OpenSolidWorksFile or GetActiveDoc.

Type: string

Required: Yes

Example: "doc-12345"

Output Properties

IsSheetMetal

True if the document contains Sheet Metal features, otherwise false.

Type: bool

Note: Returns false if the document does not contain Sheet Metal features, if the document is invalid, or if an error occurs during the check.

Usage Example

Scenario: Check if a SolidWorks part is a Sheet Metal part

Configuration:
- DocumentId: "doc-12345"

Result:
- IsSheetMetal: true (if the part contains Sheet Metal features)
- IsSheetMetal: false (if the part does not contain Sheet Metal features or if an error occurs)

Error Handling

Important: The activity handles errors gracefully:

  • If InvalidOperationException occurs (e.g., document not found or invalid document type), IsSheetMetal will be set to false
  • If any other exception occurs, IsSheetMetal will be set to false
  • The activity does not throw exceptions - it always returns a boolean result

Note: A false result may indicate either a non-Sheet Metal part or an error condition. Ensure the document is valid and open before using this activity.

Important Notes

  • The document must be open in SolidWorks and accessible via the DocumentId
  • This activity checks for the presence of Sheet Metal features in the document
  • Sheet Metal parts can be converted from regular parts using CheckAndConvertToSheetMetal activity
  • Use this activity before performing Sheet Metal-specific operations like exporting to DXF
  • The activity does not register or capture document IDs - it only checks the existing document
