How to fix merged SOLIDWORKS macro errors

Symptoms

SOLIDWORKS macros work correctly independently but failed to work when merged to one. Possibly, the error is displayed: Run-time error '424': Object required

Cause

• Merged macros might not be compatible
• There might be required initialization from the source macro which was not copied to the destination macro
• Variable naming might be different between source and target macros

Resolution

• Identify which line fails
• Check the state of variables. Hover the mouse and see if it is not shown as *Nothing *in the tooltip.
• Make sure that the correct portion of the macro is copied
• Make sure that required initialization is copied as well (if applicable)
• Make sure that the variables naming is consistent
