Step Down Connector not drawing accurately

425 Views, 7 Replies

We are using CADMep on AutoCAD 2013.  We are having a problem drawing the Step Down Connectors for ductwork properly.  We encountered this problem in CADDuct Solids as well, the 2002 version of CADDuct drew it correctly.

 

-We have our material for ductwork come in at 1500 wide rolls.

-When we add flanges to our ductwork we take off the amount required to form the flange

-When we use step down connectors it does not take off the required amount, creating length discrepencies.

 

For our Step Down 25 TDF35 Connection we need to take of 80mm from the sheet, 25 for the step down and 55 for the flange, This should leave a piece of duct 1420 Long, with no connection on other end.  When we draw it in CADMep, it draws the length from the case, not the step down.  Is there a way around this?  We enter the length at 1420, but draws it at 1460.

 

We have encountered this problem before, with CADDuct Solids and were wondering if it has been addressed?

Could you post that DWG file so we can see how your connector is defined.

Thanks

You cannot add the extension to the connector as this gets added to the length.Take that off and it will be good other than the graphics.This has been this way for the 12yrs I've been using the program

Just to show I'm not an expert (I know very little about everything), to understand this post correctly, would a stepdown connector be like a flush bushing in plumbing? Hi Bob, happy retirement.

ok I just noticed the pix and see its for transitioning from lined duct to unlined. You learn something new every day. I have always used a taper/transition in my former life. Ah metric, those were the days.....but then I was hand drafting and graphics were no problemo

Alright, we will take  the extension off, and just change the way we show our step down connectors.  If this is the way its been done for 12 years, should work for us.

Have not retired yet,just took some months off((deserving I believe after 30 years)I have some unfinished business before I think about retirement.Back to the original post,If you delete the ext and look at the developments and the x or y you will see that it is correct.

 Just have to deal with the graphics.
