FYI,

When working with the Extruded parts portion of the solid modeling tools, If the construction path is longer than the material length, a "joint" is added to the part this makes perfect sense, But if the 2D profile that is used for the extrusion happens to be "deeper" than the width of the material, No joint is added. Example might be a 32inch deep solid surface countertop where the material is only 30 inches wide.

Just happened to run across this occurance trying to quickly show someone how to use the tool.

It might be possible that this could actually cause a problem for someone, so I thought I would throw it out there.
