=IF(Right_Num_Plate=1,"MITER 3 5",1) 

This seems to  be making my mitre a 1 or 0. 

I would like to set a condition that if the Mitre is a 0 and off it doesnt draw the parts after it in sequence. 

Its a product for suite surrounds and some are just a Casing, some have returns, when  they dont have the return id like to turn the mitre off. 

Can i put an IF statement in to the DRAW3DBOX field and just turn all the parts off and not draw them.  

I also notice a triangle adjacent to the panels when im turning panels off, whats that about?  I can turn the check button off for that part, make sure it isnt drawing the part but deleting the DRAW3DBOX, make its value a 0 and i still see the left over mitre sitting next to my part. 

I asked my rep but havnt heard back, and im a little stuck, i havnt been able to make the formula calcuator work yet, it doesnt allow me to input what function im trying to work with so im taking bits of code from other products and trying to frankenstien it together and its really not working well at all.
