Slicr vs Freecad Where has my hole in the YZ plane gone? I am new to freecad and 3D printing, but not CNC and mechanical design. I have successfully created some fairly complex objects, but there seems to be a rule that I am not allowed to violate. I seem banned from creating holes in the Z plane. The attached image shows my very simple object: 20x20x3mm plane with 10mm hole in the center oriented in the YZ plane. You see both its representation in Freecad (0.16 r5754) and in slicr (1.2.9). What have I failed to understand?

Thanks to all for the help, and Happy New Year.]]> snblitz Slic3r Wed, 30 Dec 2015 16:09:39 -0500 https://reprap.org/forum/read.php?263,601529,601896#msg-601896 Re: Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601896#msg-601896
I recommend OnShape.com -- this is a free full-featured cloud-based CAD system. I was surprised to find it is about as fast as FreeCAD. In its free mode, OnShape limits you to a total of 100MB of private files, and 5GB total. In my view, this is saying that they'll give you their work (OnShape) for free if you'll share your work (CAD projects) for free, which seems a very reasonable proposition.]]> frankvdh Slic3r Mon, 28 Dec 2015 20:56:27 -0500 https://reprap.org/forum/read.php?263,601529,601890#msg-601890 Re: Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601890#msg-601890
FreeCad Basic Part Design
one ends up with a part that exhibits the same failure. The pocketed material is not removed from the design.

I create the L bracket in the XZ plane via a sketch and pad it into the Y plane.
I then select the upright surface and use a sketch to create the holes via pocket.
I use the same process for the upright holes, and the hole in the base.
In the end, the holes in the upright portion do no appear.]]> snblitz Slic3r Mon, 28 Dec 2015 18:34:42 -0500 https://reprap.org/forum/read.php?263,601529,601874#msg-601874 Re: Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601874#msg-601874 I just tried the workflow you suggested and indeed the circle appears in the YZ plane as expected. Thank you for the solution.
My original work flow works fine in the XY plane, but not in YZ for reasons unknown.

To answer your second question I reduced my problem to the simpliest manifestation of the problem so as to simplify the question in my original posting.]]> snblitz Slic3r Mon, 28 Dec 2015 18:19:15 -0500 https://reprap.org/forum/read.php?263,601529,601570#msg-601570 Re: Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601570#msg-601570
How do you create your part in FreeCAD? What I did was to create a sketch, draw the square, then draw the circle inside it. Pad that to create the object. Export the Pad to an STL file.

Is there any particular reason this has to be in the YZ plane? If not, do it in XY and then rotate (either in FreeCAD or Slic3r) to the YZ.]]> frankvdh Slic3r Mon, 28 Dec 2015 03:37:43 -0500 https://reprap.org/forum/read.php?263,601529,601531#msg-601531 Re: Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601531#msg-601531
If not, look at the stl export settings in FreeCAD.]]> the_digital_dentist Slic3r Mon, 28 Dec 2015 01:33:29 -0500 https://reprap.org/forum/read.php?263,601529,601529#msg-601529 Slicr vs Freecad Where has my hole in the YZ plane gone? https://reprap.org/forum/read.php?263,601529,601529#msg-601529 I have successfully created some fairly complex objects, but there seems to be a rule that I am not allowed to violate.
