Surface Normals

[cadcam]

Ok how can you change all the normals in one shot, so say they all point out from the model.

When i do set in top veiw they all point up even the surface on the bottom of the model,so i have to flip the bottom ones out away from the model.

What veiw do i need to be in or some thing.

This would be vary helpful folks for me.

 

thank you guys for your time.

If we knew which way was in, you'd essentially have a solid, not a set of surfaces.

You'll still have to rely on your brain for this one. Damn, eh? The bottom surface is just a single surface out somewhere in space as far as the database is concerned.

that is what i thought thanks.

So my best bet is to change it to a solid then create the surface from there for a fast thought.

Does this sound right by your thoughts?

Thanks dave.

I would agree with that especially when using flowline toolpath's from V8 & older. Funny how most things always revert back to that "brain" thing.

Thanks for the patches the other day Jay. I have not tried them yet, but I will before Friday.

Trevor,

I have question for you how many meals do you eat a day.

Do you do the 5 to 6 meals a day plan?

And do you do splits routines or singles per a day.

Man do i miss the the days of iron.

LOL!!!!

No matter how good the software gets, it still requires you to have a brain. Except for Pro/E. They, of course have the "Magic Machine" button. ROTFLOL!!!!!!!!

Jay,

You doin' a flowline toolpath or offsetting Surfaces? That's really the only places it matters ya know? Eh? (I love that, I'm surprised more of our Canadian friends dont "say" that in here. My sister in-law is from Kitchener, Ontario and she says "Eh" often and she's been here for like 10 years.

James what is happen is that i am makeing STL files to bring into Predator VCNC so i can use this as stock.

for it to come in clean from a STL i make in mastercam it wants to see the Normals pointing out or in.

On all surfaces then it brings them in clean and i can do forgings like this.

So i was looking for a really simple click and the normals all out or all in.

James - A good number of the In-House people live in Kitchener, right next door to Cambridge, where our head office located.

'Eh?' let's us change a statement into a question at the last second. Brilliant. I think we hold back here for fear of ridicule.

When doinf fillet surfaces the orientation of the normal vector is also important.

Very important also for all 5 axis toolpath machining. That's a few more occassions, eh!

You'll get none from me, you "guys " are A-1.

All vary inportent when offsetting surface too.

Many good resions for surface normals.

just trying make my customers life easer.

Thanks guys.
