How to Setup and Import ECO changes with 3DQPress inside SolidWorks


Welcome to Setup and Import ECO changes inside unfolded 3DQPress model.

After the model has been imported SOLIDWORKS assigns a different ID code to every model. In this blog, I will explain the 3DQPress process on how to use the original model, import the ECO changes, and then update the unfolded model.


1. Import the model, and then save the file name as needed then close the file.

2. Using SolidWorks open a new part file.

3. From the top ribbon select Insert\Part.

11. 3DQPress imports the top and bottom surfaces from the ECO Rev B model at the same Origin as the reference model.

12. Now the Referencing model can be updated to the new ECO Rev B change, and because the ref. is still locked it will not affect the unfolded model until you unlock the referencing updating the model when you decide limiting the affects of the SolidWorks ID.

13. Reorder the surfaces in the tree above the Imported1 feature.

14. Make the changes to the model referencing the surfaces using SolidWorks modeling techniques, and then hide all reference surfaces.
