stl verify issue

[Guest]

I have a part that I have been saving as an stl along the way a different OPS. I get to this one opm I save the stl, I go into the next op2 and rotate the stl to be in proper cutting position and it will not render. If I tell it to use the stl as save it will render that but I rotate it so it is standing up and it will not render.

 

 

 

Any way around this one that antone is aware of?

I rotate/translate my stl files all the time without any problems. Are you using x-form stl?

[Mike Whitten CAD/CAM Contractors]

I haven't heard of that one yet. I imagine you have tried all of these but here are the only work arounds that I could think of.

 

1) Try different tolerances when exporting STL

2) Rotate it in a different cad package or older version of MC.

3) Don't rotate it. Just use the WCS to progam the parts with the stock view always being TOP ( system)

we don't move the model between operations, we use named wcs for each operation. In verify you will never have to worry about xforming the stl model everything stays in world coordinates. Also if customer changes the model it is very easy to adjust what ever operation needs to be fixed.

I have had good luck moving this through the several operations, I am just wondering if I hit a point where the finished surfaces were just creating too large a file.

 

I have had several crashes just trying to load it. The stl file is nearly 60 megs in size by itself

What I might try in that case is to change my original solid model (in Keycreator in my case) to reflect what has been machined to that point, then export that as an STL and use it.

+1

Yes +1 on the WCS. John you are a genious with MC and Post's. What are you doing up there buddy? I started using WCS about 2 years ago and never went back. No more watertight errors. John come back to the light!

I ever tell you that overwhelming stress can sometimes make me stupid?

 

 

Grrrrrrrrrrrr

 

Though some people would say it doesn't take stress to make me stupid

[SaltyAcres]

john, I myself had that same error or stl, maybe the size, my supplier had no comments on , but would send it in to mc quality

By rights you should be able to move your .stl where ever you want. I used to do it that way all the time until I got sick of the errors and learned how to use wcs. Now I'm going back to the old .mc9's and converting them to wcs when I get the time. So much less data to store and back up too!
