I'm working with several plastic parts imported from NX (Parasolid) and my job now is to modify them with Solidworks, so I have to find the best way to transform the part in order to make it parametric but taking advantage of the geometry already existing.
I guess that Feature Recogniser should be my very best friend in this kind of situations, but I'm not taking a good advantage from it because the pieces are a bit complex and I'm not using it as deeply as possible I think...
Anyway, I'm posting a typical example and my particular solution explained.
It would be great if you take a look and suggest alternatives and feature combinations that can improve my current approach. Specially into the 4th step, where I tried different features that didn't work and I don't know why...
The point here is to transform this part...
Into this one... But with parametrical thicken and fillets and everything possible, not just deleting and moving faces.
Here a picture of the most conflictive step (Add low surface):
My feature tree has been the next, divided in 5 main steps:
1 - Prepare and place geometry (Move, Offset 0mm, Delete face)
2 - Make thickenable (Delete faces, Untrim, Surfaces, Knit) -Knit step can be avoided by merge option into Surface fill and Untrim-
3 - Kill fillets (Delete faces, Untrim, Heal edges, Surfaces, Mutual trimming, Knit and Fillet)
4 - Thicken (Cap and Shell)
5 - Add low surface (Extrude Cut, Delete faces, Knit already prepared faces) -Before the Extrude Cut option I tried Parting line, Project line and extrude surface up to body... even running 1mm through the faces to cut, all with the same Sketch.)-
6 - Offset low surface (Delete face, Offset, Untrim, Filled Surface)
As I said, I'm just looking for suggestions and alternatives in order to make a better use in the future, so all you can contribute will be very welcome.
