You may have created mutibodies by cutting extrusion.
Check whether you see "Solid Bodies" on the tree.
You may, by accident, "hide" those bodies. Then, it behaves like the way described.
Hi
I'm not familiar with glass industry. Is there a straightforward way of estimating glass cost?
Let's say current 2 ft X 3 ft X 3/16" thick glass costs me $10. Then, what would be the estimated cost of 1/4" thick glass if all the other edge/finish/qty etc conditions are identical.
I'm coming...
Anna already gave you a hint.
SolidWorks is capable but probably not the way you expect it to behave. You should not expect two different products look and feel exactly the same.
