Hi everyone, new to the forum and this is my first post so im hoping that you guys can help me. I have solidworks 2013 professional and i am experiencing problems with the toolbox feature. I have an assembly of a part with some bolts taken from the toolbox and placed in the assembly. These features are not rebuilding properly and end up as looking out of diemnsion. The toolbox parts have rebuild errors and when i open them seperatley each one has some problem with the sketches or features. What can i do to solve this problem.

Cheers
