Klog:

Sorry to be late in answering your question. I've been raising a frame the past 2 weeks (just a few days left).

I'll need more specific information to give you a specific answer. I can only give you this general advice:

- Your timbers must be components, and they must not be part of any other component or group.

- Your joints (tennons) must be sub components of a timber component.

- When you create a joint, you must set it to cut an opening, and you must set the cutting plane to be the plane where it will intersect with the mortised timber.

- After you have created a joint component, you must right click on it, and select "TF Create Joint".

Hope that helps. CB.
