The resulting angle between the segments is too great.

[danhaga917743]

I am getting this error when trying to connect 2 pipes using the "Trim/Extend To Corner (TR)" command in Revit MEP 2012 and 2013.


Error: The resulting angle between the segments is too great.


Is there a way to change the angle that triggers this error?


I am creating as-built models of MEP spaces so my pipe runs aren't all straight and perfect like Revit wants them to be and I need to be able to connect pipes that are at off angles. Take a 110 degree bend for example. I know the generic elbow can handle this but how can I get Revit to insert it that way and bypass that error.


If I try and drag the pipe ends together I get the same error or this one "No auto-route solution was found".


Anyone have any suggestions or workarounds for this error other than manually placing elbows? I would really like it to work with the Trim/Extend command.


Thanks

First, you'll want to use the align command to make sure both pipes are on the same plane and/or are lined up. Also, the elbows will not permit angles less than 90 degrees. You mentioned 110 degrees so maybe things aren't quite lined up. The other thing that might cause issues is if the pipe type you're using doesn't have the routing preferences set to use the correct fittings. If you've already routed some pipes and they all worked fine then that last point would be moot.

I am 100% sure everything is aligned and even tried again after using the align command and got the same results. I am using the default generic/standard pipe/fittings that ships with Revit.

I am not worried about this being able to be built because it is already built. I am laser scanning existing MEP spaces and trying to recreate them accurately in Revit.

I have links for sample files files.

JPG: Lets call this the as-built. This is what i want the Revit model to look like.
PCG: As-built scan data/pointcloud. Insert into Revit Center-to-Center.
RVT: This is a revit file with standard pipes fit to the scan data. All pipes are aligned and meet at the end points. From this point I would like to be able to go in and simply use the TR command to connect the segments for a result that looks like the attached JPG.

Make sense?

try creating it with Place Holder pipes, then convert to full pipes. i've had better luck with place holders connecting at funky angles, then once it's connected, revit seems to be able to convert to real pipes much easier... worth a shot anyway...

It appears from the jpg. that the angles will be too tight for the standard elbow fittings in the front two runs, and too shallow for the run in the back. The angles that the elbow family works with are between 10 and 90. Meaning the angle between the pipes can't be less than 90 degrees (as is the case with the runs in the front) and can't be greater than 170 degrees (the case in the back). I'm not sure why elbows behave this way since those same angles work just fine when you open the family itself and flex the angle parameter.

A possible solution would be to model with 2 elbows connected back to back. I included a screenshot of that example. One elbow is 45 degrees and the other I show selected is 55 degrees to get a 110 degree bend. For the shallow angle you can use two 45 degree pipes with one slightly rotated in order to get the desired angle. It will cause your pipes to be slightly out of alignment though.

Hope it helps!

That was fun.... I played around with the model you posted. I got them to connect but aint no way possible your going to get the with just "trim" command. Look at the image i attached. pipe on the right is yours and the one on the left is mine. I would recommend just doing a straight pipe down rather than having it at an angle. (the down angle pipe is your problem)
