when i create a constraint it turns red and I don't know why. in the pic the "green pipe" is constrained to the grape colored box. it has an axis on the box and the axis on the pipe. this way I can rotate the pipe to where I want it. If I suppress the "green pipe", the the constraints turn black., if i un-supress the "green pipe" then the constraints go back red. what am i doing wrong? I can't see how there is a conflict with this, i guess that is what that means. I do have a "package" file of this, it is 3.7mb also i have shut off the error messages and don't remember how to turn on.
