WTH?

[David]

Was going to print this bracket.

But it looks like this in the slicer.

@jcdammeyer I drew this in Atom which has never given me a moment's trouble exporting as STL till today.
Any ideas what might be going on here?

That is a crazy glitch. Kind of neat tho. No idea how to fix it.

I'm also of no help which explains why you've asked for John or maybe Paul.

That reminds of one of the out takes from Shrek where they show donkey turning into a big fuzz ball, totally not what the programmers were expecting.

I exported from Alibre Atom to Fusion where I then exported as an STL.
Opened in Sovol Cura slicer and it looks perfectly normal so it has to be something in Alibre Atom that is not set correctly.

So now the test print or are you cutting aluminium?

Send me the Alibre part file. Let's see what mine does.

Just a test print so I can see if my motor mount design will work.

BTW, I think there is likely an export parameter that deals with curves and how they are generated. If drawings curves is switched off or resolution is set with the decimal point in the wrong place then kaboom! Straight lines.

I'm definitely thinking it's an export parameter.
This is what set now.

First of all no problem bringing in the part file and exporting it as an STL. Nice roundy bits.

Mine is set to millimetres rather than design units and 1 degree. I'll change it to 5 and see what happens.

No difference.

 

[David]

The only difference would be the units then

 

[jcdammeyer]

Might be worthwhile asking that question on the Alibre Forum. I switched to use design units and that worked too. What did you draw it in? Inches or mm?

Edit: BTW, I measure the inside hole as 95mm

MM always.
I am noticing something odd. After I export to STL, Alibre sits and writes files to disk for ages. No idea what's happening.

 

[David]

I literally have no idea what was going on but I closed Alibre, closed Chrome, restarted my laptop, fired up Alibre, re-exported and boom, no problem.

I'm going to guess that Chrome or some other program modified a PC parameter that was used by Alibre Atom. Does it take a long time to write it out now?

Nano seconds now, just like it used to be
Appreciate you double checking my file!
