Why are some lines in my Fusion-360-drawing not in the dxf-file?

[Anonymous]

Hi all,

Yesterday i had my first experience with an lasercutter in an basic course.

Really excited, great fun!

In this course, the participants were asked to make some quick drawing on the laptop which was connected to the lasercutter (in the program Lasercut)

Fortunately i was able to upload the dxf which i saved from a design i had made in fusion 360 before,

On the laptop, some lines appeared to be missing (like the end of the tail and the bottom of the paws) but i was able to recreate them.

Afterwards I was able to lasercut my first work in progress, which made me really happy.

Now i realise that i wasn't just missing the parts of the paws, but the entire block around the dog ('the dog house')

In Fusion 360 these lines are present, but somehow they don't seem to be exported to the dxf.

Does anyone have an idea what i have been doing wrong (i'm new at Fusion-360 and learning a lot but i'm not sure where to look now)?

(what could cause these line not to be present?)

I hope someone can help,

thanks in advance!

Fred.

Hi,

Check your line weights and colors and layers if your sending a dxf file to a laser instead of a g-code file.

Could be some of your drawing was on different layer.

Hope this helps.

Hi John,

thanks for your support!

Not sure if i did something with thickness, layers or colors,

I'm new with Fusion and not even sure how to do that,

but maybe that's even a better reason to check, maybe i did that without knowing.

Thanks

@Anonymous could you post your model, it could be a bug with selection this sort of thing has come up from time to time, and no fusion does not have layers, line weight or colors in the sketch environment.

Hi Daniel,

thanks to you too for replying!

I've found where to save my model, and have attached it (hopefully, this is the right filetype).

For now i will call it a day (23:17 overhere), but tomorrow i will continue,

thanks for all the help!

Fred.

@Anonymous it must be a bug with fusion or what the laser needs to see, the file looks fine in a program that uses dxf that I have after export the dxf out and it inserts back into fusion fine.

Do you have a program you can look at the dxf with before they are sent to the laser.

I have seen some problems where Fusion exports some profiles as polylines and some programs can't read them. In your file the rectangle and the house are exported as polylines, it looks like the rectangle was read OK though. Try the file attached, I've exploded the polylines in Rhino. If you need a program to explode the polylines try QCad.

Thank you both very much!

I have to go to work but couldn't help to see if there was an answer,

thanks, really good to know that there doesn't seem to be anything wrong with the way i made the drawing,

i will take a look at the file and the programs mentioned!
