I'm trying to use cuboid from bosl2 to round off a cube. It works fine except that, as the help says, cuboid centers by default, and in my object my cube is not centered. What it doesn't say or give any examples of (that I could find) is the syntax for center = false. I have tried every combination I can think of, but have not yet found the magic one. The first line is the line I have- it works fine. Below it is the cuboid line- it just gives me the error "variable center not specified as parameter". cube ([curve_diameter*3,curve_diameter*2.5,curve_diameter*1.5]); cuboid ([curve_diameter*3,curve_diameter*2.5,curve_diameter*1.5], center = false, rounding=2); Can someone put me out of my misery and tell me where "center = true" goes in a cuboid statement? -- Cheers, Ken bats059@gmail.com https://vk7krj.com https://vk7krj.com/running.html ---------------------------------------- A baby can be defined as an ego with a noise at one end and a smell at the other.

Hello Ken, center is not a parameter cuboid has defined in it's parameter list.  See shapes3D.scad where Cuboid is defined which parameters are available. Alternative solution: EDGES_SIDES=[[0,0,0,0], [0,0,0,0], [1,1,1,1]]; my own parameter cubSize=[100,100,80];   translate([0,0,cubSize[2]/2])     cuboid(     size=cubSize,     // p1, p2, // if not defined, Cuboid checks on it     //chamfer=10, // Use chamfer or rounding, not both     rounding=5,     edges=EDGES_ALL, // If you want to round e.g. the sides only you replace EDGES_ALL by EDGES_SIDES here     except=[],     //except_edges,     trimcorners=true,     teardrop=false,     anchor=CENTER,     spin=0,     orient=UP ) ; Hope this helps.

BOSL2 objects are positioned using the anchor= argument. It sounds like you may want anchor=[-1,-1,-1] or alternatively anchor=FWD+LEFT+BOT You might want to read the tutorial: https://github.com/BelfrySCAD/BOSL2/wiki/Tutorial-Attachments On Fri, May 24, 2024 at 6:12 AM Hilbrand Klaver Gmail via Discuss < discuss@lists.openscad.org> wrote: > Hello Ken, > > center is not a parameter cuboid has defined in it's parameter list. > > See shapes3D.scad where Cuboid is defined which parameters are available. > > Alternative solution: > > EDGES_SIDES=[[0,0,0,0], [0,0,0,0], [1,1,1,1]]; my own parameter > > cubSize=[100,100,80]; > > translate([0,0,cubSize[2]/2]) > cuboid( > size=cubSize, > // p1, p2, // if not defined, Cuboid checks on it > //chamfer=10, // Use chamfer or rounding, not both > rounding=5, > edges=EDGES_ALL, // If you want to round e.g. the sides only you > replace EDGES_ALL by EDGES_SIDES here > except=[], > //except_edges, > trimcorners=true, > teardrop=false, > anchor=CENTER, > spin=0, > orient=UP > ) ; > > Hope this helps. > > Regards > > Hilbrand > On 24-May-24 11:03 AM, Ken via Discuss wrote: > > I'm trying to use cuboid from bosl2 to round off a cube.

 Hello Ken,

 center is not a parameter cuboid has defined in it's parameter list.

  See shapes3D.scad where Cuboid is defined which parameters are
 available.

 Alternative solution:

 EDGES_SIDES=[[0,0,0,0], [0,0,0,0], [1,1,1,1]]; my own parameter

 cubSize=[100,100,80];

   translate([0,0,cubSize[2]/2])
     cuboid(
     size=cubSize,
     // p1, p2, // if not defined, Cuboid checks on it
     //chamfer=10, // Use chamfer or rounding, not both
     rounding=5,
     edges=EDGES_ALL, // If you want to round e.g. the sides only
 you replace EDGES_ALL by EDGES_SIDES here
     except=[],
     //except_edges,
     trimcorners=true,
     teardrop=false,
     anchor=CENTER,
     spin=0,
     orient=UP
 ) ;

 Hope this helps.

 Regards

 Hilbrand

 The first line is the line I have- it works fine. Below it is the
 cuboid line- it just gives me the error "variable center not
 specified as parameter".

 cube ([curve_diameter*3,curve_diameter*2.5,curve_diameter*1.5]);
 cuboid ([curve_diameter*3,curve_diameter*2.5,curve_diameter*1.5],
 center = false, rounding=2);

 Can someone put me out of my misery and tell me where "center =
 true" goes in a cuboid statement?

Many thanks Adrian- you not only fixed the problem, you also gave me a good laugh at myself. I was an electronics tech for 30 years before I retired, and many many times would have to write on the fault report "RTFM"-  which translates as "read the flippin' manual"!! Your solution worked a treat- and I now have yet another manual to read. On 2024-05-24 22:37, Adrian Mariano via Discuss wrote: > BOSL2 objects are positioned using the anchor=  argument.
