It is explained that Merge entities means merge faces with the same underlying geometry.
Face has been created with the base of the underlying geometry. What is the purpose of merging it?
It will often create a more continuous join when you are stitching 2 surfaces together, to give you a better model. This does of course depend on the surfaces you are stitching.
Merging allows for two or more surfaces or surface bodies to become one. This is one situation where more is not better.
Seems to me merging surfaces into a single quilt would be a desirable thing when knitting them... so why is this not the SolidWorks default?? and can I change that default somewhere? Pro/E (CREO) handles this better. What a pain to have to select/change this setting every single time... especially when knitting many surfaces... (and yes I know you can do many surfaces in a single knit but only if they are all joined). I hear users say that SolidWorks is "easier to use" than Pro/E CREO... but at times like this I have to disagree. Ok, end of rant.
In this model whether it is possible to see any differences when merge entities is checked or unchecked. Because I couldn't see any differences.
Check the surface Bodies folder
Result is same.
