I'm not sure how to attach a mpc to a quick responce so here is the mpc.

Perry the pattern you made can only be used by those with the 3d suite. To make it so anyone can use it do the following:
1) open the mpc
2) remove one of the boards and select all by pressing CRTL+A
3) click on GROUP
4) above the items is the word group, click this
5) click on make pattern icon
6) choose location to save and name

Now do the same for the other board. This will give you two patterns, one the tongue the other the groove. place them on a new board save as mpc and upload it to the forum if you want others to be able to use your pattern.
Thanks for your work on this.
