Need Help!- Could someone please help me with this?

Hey guys,

I'm in dire need of help here, I am quite new to CAD and have a pretty major problem.

I have a file that i have asked a local machinie shop to laser for me, but they said there is problems with the file.

First of all it was duplicate line issues, so i did LOTS of googling to research the 'overkill' tool

This worked for the most part, but there seemed to be some lines it could not remove, i could not manually find these.

So after more infestigation i THINK I found them and removed them, however now i am having issues with the machine not seeing lines.

The company thinks its somthing to do with layers and lines being hidden, i honestly have no idea whats wrong

Could someone please help me if i upload my file?

(also how can i upload my file?

Thank you in advance for help, i really need this!

Maybe they can't work with surfaces. I extracted the profile from the surfaces and saved it as a 2D dwg file.

This may do what's require. I have rotated to the XY plane and moved to Z0.

Check before machining!

Edit. OK. I've omitted the cutouts......NOW corrected

Thank you guys.

I have uploaded & emailed this to the company i REALLY hope that this works.

I have been really struggling with this, again i appreciate your help guys!

ok a couple of things, and based on what we do .

The cut will be in the "z" axis ( your view is in the Y so the laser only sees a layered line)

Cut line are polylines to 2 dec places. ( this is more to do with "kerfing" of the corner radii but just plain good house keepin')

Each cut is an individual "item" ( yours is a "block" ) This makes it easier to set the cut path, lead ins - out etc.

Now the cut width is also an issue with laser, thicker material will not have a straight cut because of the focal point of the cut. might not apply to you in this job, but always ask what is the cut width ( say 1.6 mm rule of thumb)

I run in to this often with dxf files for our waterjet.
lines must be in the same plane
lines must be continous
you can't have any blocks
hope this helps
