Exporting to STL for 3D printing

Postby gryffin13 » Mon Jul 20, 2015 1:33 am

I am really struggling being able to print anything I design in freecad. The exported file does not match the design. It leaves out feature, typically cuts and I have no idea how to fix this. For example, this is what my model looks like. This is the STL when imported to print. I'm afraid there isn't a simple fix to this, but I'm hoping someone with more experience might be able to help me?

you have to take into account, that FreeCAD exports only selected parts.
So look at your object browser and select all parts, that make up your solid - selected parts show up in light green.
When your whole part is green, you probably have all relevant parts selected.
But be careful, not to select subparts too.

So for your cut, you'll find a "cut" entry in object browser, which has 2 subparts. "cut" should be selected, the subparts should not be selected.
Ctrl + mouseclick is your friend :)

Thank you for the answer. I am not totally understanding what the important subparts are. But I did mess around with unselecting some parts and was able to get it. In the future I'll try to learn exactly what is happening, but I have my part. Thanks so much!

I figured there was already something, but truthfully, I found the forum very difficult to search/browse. I knew somebody knew the answer - and they did. I appreciate the help.

And sorry I took so long, sadly this is only something I can work on on the weekends and finally got back to it. Thanks again!
