====== Overlapping boxes ====== > **Summary:** //One of the rules when using FilletEdge is that three surfaces must meet at a point. In this example, there are four surfaces to deal with.// ---- \\ | {{:legacy:en:OverlapBoxesStart.png}} | Original overlapped boxes. | \\ | {{:legacy:en:OverlapBoxes2.png}} | Use FilletEdge, radius .25, to get most of the work done. | \\ | {{:legacy:en:OverlapBoxes3.png}} | Extract the four fillet surfaces from one corner and untrim one crossing pair. | \\ | {{:legacy:en:OverlapBoxes4.png}} | Use FilletSrf with a radius of 0.25, to create a fillet between the untrimmed pair. | \\ | {{:legacy:en:OverlapBoxes5.png}} | Trim and delete the extra surface pieces. | \\ | {{:legacy:en:OverlapBoxesEnd.png}} | Join into a closed polysurface. | \\
