Duct Take-offs

[CarrieHoffman02]

I am new to MEP 2009. I have opened a 2008 drawing and my fittings are messed up. I use the beveled takeoff and now it shows something that I don't want to see. (I have uploaded this) I realize that this is there because it isn't "connected." Please look at my drawing I have more questions there.

Thanks in advance
Carrie

The diameter of the round branch shoe exceeds the depth of the rectangular duct. At no point should the depth of the shoe be greater than the duct diameter. The shoe should be more like flat oval at the interface with the square duct. Top down plan looks OK in MEP2008 but in 3D SW isometric view it looks bad.

I would be using multi-shape rectangular to round duct shoe branches and am not familiar with 'beveled takeoff'.

I am not running imperial libraries and not upgraded to MEP2009 so I am not sure how relevant my comments. If it was originally OK in MEP2008 then it has not survived the round trip to MEP2009.

To one of your questions: how to make disconnect makers go away
Disconnect maker is just a maker that display some objects disconnected. If you would not like to show those makers, you can find the Show Solution Tips option on View menu tab and uncheck it, it could help you out.
To your question: how to get rid of something that I don't want to see on takeoff
It looks like that the diameter of that round takeoff is bigger than size of rectangular duct. I think you can change the takeoff to anther types such as Conical takeoff and Bellmouth takeoff.

A 14 inch diameter duct should come off a 26x16 duct just fine. It should go straight into the side of the duct like a rectangular tap and then flare out to a round duct. It worked in 2008 just fine.

I'm not sure why it displayed correctly in 2008. It should have had a
similar display as what you are seeing in 2009. The takeoff fitting used
has a larger depth than the main duct. I have a low loss takeoff that
will accomplish what you want. It'll correctly display a round duct
takeoff equal to or smaller than the depth of the main duct (16 dia
takeoff from a 26x16 duct). I'll upload it if you are interested.

Please upload it. What do I do with it after I load it? Can I add it to the library or do I have to place it manually every time?

Thanks

It can be loaded and set as a default. Here is a screen shot.

Thats perfect. Can you walk me through the steps to load it please?

I'll upload the content for two fittings. One for round takeoffs from a
round duct and the other for round takeoffs from a rectangular duct.
Attached is a zip file containing 6 files. A .dwg, .xml and a .bmp for
each takeoff. Unzip these files into the directory defined in Options
on the MEP Catalogs tab for Duct. The first part of the path may be
unique to your company setup but the last part will be:
\Aecb Catalogs\US Imperial\Duct\Round\Takeoffs

The Duct catalog now needs to be regenerated. The command is
_AecbCatalogRegen or it can be selected from the CAD Managers pulldown
menu. The part is now ready for use. Set is the same as any other takeoffs.

The takeoffs are set for Slip Joint and Undefined Connection Types. If
you need others such as Banded, let me know and I can step you through
the process.

Glad to help.

Can you please repost the takeoffs file, for somereason when I click on it, it gives me an error. This problem with the beveled takeoffs is due to Autodesck not creating the parts accuratley or correctly, it is very frustrating. Thank you

I should mention this part was originally created by someone working for
Autodesk in the UK. It would be nice if it were added to the standard
library of parts shipped with MEP.

Just what I needed. Thanks.

Andrew, Hopefully you are still watching this thread. I downloaded your duct takeoffs a while back and they worked just fine in MEP 2009 and 2010, but in 2011 I am having a problem with them. It has started leaving gaps where there should be a solid line. I am uploading a picture of the problem. It seems to do it no matter what size I am using. I know I could probably just modify the top view of the block, but I am not sure how to find that or where to look for it. Do you have any suggestions?

Thanks

Carrie

Thank you, I have been looking for something like this.  I can't imagine why Autodesk would't have this in the default library.
