Hi guys.

I'm working on an extrude cut on the surface using a variable pattern in solidworks, and an error occurred during this process.

I checked that the extract cut job was completed by fetching the Excel file that recorded the feature and the start point of the job.

However, the VarPattern tab encountered an error such as the following picture, 

and for some instances

Cut-Extrude2:Seed feature,
Cut-Extrude2,
