ANYONE KNOW OF A GOOD AUTOCAD PIPE FITTING ADD ON?

I am looking for a autocad add on program that will allow me to insert pipe fittings, flanges, ect. ect. I prefer the pull down menus those are really nice. The thing is, is I don't know much about piping so a program that takes the guess work out would be nice. one example is i don't know how much to trim off of a pipe in order to connect a welded 90 to the end of it. one major problem is it would have to be compatible with 2009 LT. But any suggestions would be helpful i may be able to convince my boss to purchase the full version of acad.

Answer:

Unions are fittings that allow local disconnections without having to cut pipe. Most traps do have 'union' fittings - but that is not the proper term. Those are properly slip-nut fittings. Both are linked below. A hard-connected PVC trap is also linked below - such a fitting will not leak if snaked (unless broken, of course). Now, it is quite unlikely that a trap such as you describe would have removable fittings - it is far more likely that the connections are solid - especially as fitted traps are more costly than solid traps and from what you describe your house was done 'on the cheap'. Note also - if you do have to get into the ceiling it would be much better were that trap to be removed and replaced in the proper location directly under the sink. If you can avoid the expense, great. But if not, you will only have to do it once.
A smoke alarm is typically a self-contained smoke sensor and alarm-sounding unit. A fire alarm may be nothing more than an electric bell with a manual switch to turn on the bell when there is a reason to evacuate the building. Or a fire alarm may have smoke and heat sensors, in addition to manual pull stations, and distributed sounders that include the ability to broadcast recorded messages about evacuation, or to broadcast specific instructions, like a public address system.
