Exporting a surface model as an stl
(OP)
Anyone know the trick to export a surfaces only model to stl file format in Solidworks?

RE: Exporting a surface model as an stl
As for getting your surfaces to a solid file you will will need to knit/close the surfaces and tell SWX to make it into a solid body, then you can save it out as a dumb solid.

RE: Exporting a surface model as an stl
Thank you for taking the time to reply. I am well aware of the difference between a solid model and a surface model. However, for what I need to do I must have an STL file with open geometry, think of a cup where the cylinder and the bottom are just surfaces i.e. zero thickness. It can be done, we have a file. I just don't know how it was done. I need to create updated versions and the guy that did the 1st one is no longer here.
RE: Exporting a surface model as an stl
I just made a simple open box out of surfaces and then selected Save As -> STL and created a file. I then opened that file in SWX to verify that it worked. I don't do much with surfaces so that explains the perspective in my first reply, but, due to your challenge, I learned something new today.
As to your original question - have you tried Save As -> STL? It just worked for me.

What version of SWX are you running? Which surface feature did you use to create the surfaces?
RE: Exporting a surface model as an stl
Could you post the file? You are likely to get faster, better help.

Solidworks will only take dimensions .00000394in (0.1micron) and larger. I did try using a very small thickness and it still creates seperate surfaces for the inside and outside of the cylinder. This causes problems with software that this is imported into.
Kevin:
I have tried knitting the surfaces, the same error. I don't think solidworks can do what I want and as I have learned more about STL files I understand why. An STL file is simply a list of triangles with the xyz coordinates of the corners and an xyz normal vector which designates which side of the surface was external to the model and which side was internal(solid). When a model has no thickness, the software cannot know which direction to assign to the normal vector.
RE: Exporting a surface model as an stl
Two questions:
1. What is the application that it requires an STL file?
2. Can you or can you not post the file?

I think closed VOLUME describes it better. The stl file is then a list of triangles that make up the surfaces of the closed volume.
Thanks for your input.
