dual extrusion merge using SolidWorks

Recommended Posts

Hi, I can't get the dual extrusion merge feature to work. I started from a solid model in SW, cut half of it off and saved it as 1.STL. Then I cut the opposite half from the exact same SW file, and saved it as 2.STL.

When I import them and select 'dual extrusion merge', the two models merge in the wrong orientation. I've tried it with a few different models, and there doesn't seem to be a consistent offset, it seems random.

Any help would be greatly appreciated.

Just had the same problem and tried using defined reference systems but did not work.

Finally discovered that you need to tick the following box in the STL output options window.:

'Do not translate STL output data to positive space'

I also had a defined coordinate system selected, but think it should work with the default.
