JUST CURIOUS, I POSTED TWO PREVIOUS QUESTIONS THE OTHER DAY FOR HELP AND HAVE GOTTEN NO RESPONSE YET, ANY REASON WHY?..........I DO HAVE ANOTHER QUESTION THOUGH...I AM USING A TRIAL VERSION TILL IT RUNS OUT, THE COMPANY HAS PURCHASED THE PROGRAM AND I WILL BE INSTALLING IT IN A FEW DAYS BUT I AM TRYING TO DRAW SOME 6" PIPE AND LOOKING FOR A 6X3 RED TEE. IT IS NOT IN THE FITTING DIALOG BOX, CAN I ADD THIS FITTING AND IF SO, HOW DO I DO IT? OR IS IT BECAUSE ITS A TRIAL VERSION AND IT ONLY GOES UP TO 4"?
