Tranform STL

[maestro]

I have done this many times but have now incountered a problem. I verify my 1st op and save as STL. If I run verify on this STL without tranforming it, the STL file comes into verify without any problems. If I go to file-converters-stl-transform and transform this file to a new location on my fixture for verification, I get he following error, LW has found the STL file not to be closed and watertight. An approximation will be used as stock. This approximation is not very good and doesn't work very well for verification of my 2nd op. Has anyone out there run into this problem and if so, did you find a solution for it?

Hey Maestro

 

There was a thread a couple of months ago covering this problem.Look here or do a search using water tight.

Hi maestro,

 

Ongoing problem here as well.

I did find that the default tolerance of .001 is part of my problem here. I tried smaller all the way down to .0002 with no luck. But when I went up to .002 it worked just fine. This was for transformed and original MC solid converted to STL. Good Luck

Where are you finding this default tolerance?

Hi maestro,

 

When you do File,Converters,Stl,Write File.

At the bottom of the screen on the left it asks you what tolerance. It comes up with .001 and thats where you change it to another value.

maestro,

I'm having this very same problem, I've tried all of the suggestions here on the board and none of them seem to work in v9.1 sp2. Ready to pull my hair out!

You can't do this from verify can you?

[maestro]

Kevin, you are correct. You don't have this option creating an stl from verify. I am using

Ver 9.1SP2 also. I only get htis error after tranforming the stl file. It doesn't happen on all of my files. I have tranformed other stl files that were created from verify. I too have tried all of these suggestions without any success. Thanks you every for your suggestions.

Maestro,

Perhaps using the WCS feature will remedy your problem. Use this to move you work view without actually changing part orientation. Since I started using WCS extensively, I haven't had to transform an stl yet. Works great for verifying multiple OPs.

[maestro]

Rick, I use the WCS function also and this works great. This particular job involves running 4 parts on a 4th axis setup on a vertical mill. We run 2 parts complete of opposite hand parts, 1st & 2nd op all on the same fixture. The parts are modeled up in MC the way they sit on 4 sides of the fixture. I verify the first op from the raw material, but then I ned to save this as an STL, tranform this to the opposite side of the fixture to verify the toolpaths for that side. If I don't transform it I don't get any errors, but then its not in the correct position on the fixture. The error occurs after transforming it to the other side of the fixture.

[kccadcam]

When you xform your stl around and then go to save,

it asks you to save it as binary or ASCII.

What's the difference and which one is better for this type of operation?

[maestro]

I always save as binary. I don't know what the difference is. I tried saving this one as ascii but I still got the same error.
