Whilst on support the other day I came across a question which I come across at least once a week, Why is the flat pattern not coming through to the drawing even though the view is set to flat pattern ?
Usually the reason for the flat pattern not coming through to the drawing sheet is not completely understanding what SOLIDWORKS completes in the background. So here goes- I will explain what is happening in the background and give a few best practices to ensure the setup is correct.
The first step in which SOLIDWORKS goes through when a flat pattern is inserted in to a drawing is actually down at the part level. It creates an additional derived configuration named – "DefaultSM-FLAT-PATTERN".
This configuration holds the flat pattern information and should remain in the flattened state so that the drawing has the flattened part to reference. If this configuration is changed to the folded state it will also update in the drawing giving the folded view.
Another common reason for the flat pattern failing is that the part is not saved when the drawing saved. This causes the newly created derived configuration to no longer exist as the part has changed but not been saved. Ensure you are completing save all within the drawing environment to ensure the part is up to date.
Take a look yourself next time you add the flat pattern into a drawing you may see something that you never knew occurred.
