Hey all,

I've run into this aa couple of times in the past, and never been able to figure out why.

I'm modeling a blower fan for my 3D printer based off of a STL file downloaded from Thingiverse.

I've done this a gazillion times, so it's all good.

I'm near the end and it looks like this:
I insert a couple of through holes for a M3 screw and the thing disappears:
If I turn on the wirebody display it's all there:
Any idea as to why it's doing this?

Thanks

LOL.

If I delete the through holes and then recreate them the issue goes away....

See if anything at viewtopic.php?f=17&t=98&p=883#p883 will help. I'd start with the first thing mentioned there.

Try hiding and then showing the body.

Has happened to me a couple of times (assuming it is the same thing).

Just Hide, then re-show resets it.

Control-Q

I beat my head against this all day today.

It's an artifact of an oldish video card and trying to reverse engineer a STL file in a part.

Once I deleted the imported STL object from the part, it all was fine.

Henceforth I'll probably do this as an assembly using the STL reference. I found it all works much better that way.

I did turn off enhanced graphics. Thanks for that tip.

Cheers
