rebuild errors

hello all,

im working on a base model in solidworks 2015 sp0. from this model i do save bodies into other parts.

yesterday when i wanted to make changes to the base model, i opened it and when i wanted to edit a feature, it automaticlly did the whole rebuild to all the features and found a ton of errors that where never there.

so i took an hour and fixed all the errors.

today i opened the file to make more changes- and again it shows a ton of errors that where never there.

btw, it doesent matter if i change the "verification on rebuild" option...

its driving me crazy....

can anyone help me?

with thanks in advance,

joel
