Hi @lishiqi,

Your boxes are invalid Rhino geometry, because their Z coordinates are decreasing: https://developer.rhino3d.com/api/rhinocommon/rhino.geometry.box/isvalid. Thus the brep = rg.Brep.CreateFromBox(geo[k]) line returns empty geometry.

If you change the line where the box is created to:

geo.append(rg.Box(plane, rg.Interval(spaceX / 2 * -gap, spaceX / 2 * gap), rg.Interval(spaceY / 2 * -gap, spaceY / 2 * gap), rg.Interval(dist / 2, spaceZ / 2 * -1)))

the boxes get added to the document.
